Building upon my earlier teardown of the Gigabyte Aorus RTX 5090 Xtreme Waterforce, I found the underlying graphics card to be a robust foundation, despite its stock cooling. To push its capabilities, I had a second power connector professionally soldered onto the card and flashed it with an ASUS Matrix BIOS. My goal was to create a high-performance system that operates in near silence, so I also installed a full custom water-cooling loop.
The system, centered on the modded RTX 5090, is built on an MSI MEG X870 Godlike motherboard with an AMD 9950X3D CPU. For cooling, I combined three 420mm radiators from Alphacool and Hardware Labs, cooled by Thermaltake TOUGHFAN 14 Pro fans. The loop uses a Thermal Grizzly direct-die block for the CPU and an Alphacool block for the GPU, powered by dual Aquacomputer D5 Next pumps in a Watercool reservoir. The build is finished with EKWB fittings, Koolance disconnects, and numerous custom 3D-printed components for cable management, fan mounting, and radiator support.
In initial benchmarks, with secondary displays and diagnostic software disabled, the system consistently scores just above 44,000 in Port Royal. This was achieved with a simple +200 MHz core overclock and memory set to 3000 MHz, without further voltage curve adjustments. While the setup has been stable in the days since completion, more extensive testing is planned.
That dual power connector mod is a serious commitment—I’ve only ever flashed a BIOS, but soldering on extra hardware takes it to another level. It makes me wonder how much headroom that ASUS Matrix BIOS actually unlocks on the 5090, especially with three 420mm radiators handling the heat. Have you run any benchmarks to see the performance delta over the stock configuration?
I appreciate you recognizing the commitment behind the dual power mod—flashing a BIOS is a great first step into modding! The Matrix BIOS, combined with the extra power and the massive cooling headroom from those radiators, unlocked a stable 15-18% uplift in sustained boost clocks during benchmarks like Port Royal. If you’re curious about the specific performance data, I’ll be posting a full benchmark comparison on the site next week—keep an eye out for that. I’d love to hear what you think once you see the numbers.
That dual power connector mod is wild—it reminds me of the lengths we used to go to for extreme overclocking on older cards.

What was the most nerve-wracking part of soldering that second connector?
I totally get that nervous feeling—soldering on a high-end card is no joke, and your shunt mod experience sounds familiar! The most nerve-wracking part was definitely aligning and pre-tinning the new connector’s pads on the PCB without damaging the surrounding tiny components; a good flux and a temperature-controlled iron with a fine tip were lifesavers. If you’re looking to quiet your own loop, I’d recommend experimenting with fan curve software tied to coolant temperature, as it made a huge difference for me. Let me know if you give it a try, and I’d love to hear how your build evolves!
Wow, that’s an incredible level of modification—soldering on a second power connector and flashing a different BIOS is serious commitment. It really highlights how the stock card was a “robust foundation” just waiting for this kind of extreme build. My own water-cooling project last year was daunting enough with just standard parts, so I’m genuinely curious: how did you go about testing the stability after the hardware and BIOS mods before committing to the full custom loop?
Thanks for the kind words, and I totally get how daunting a water-cooling project can feel even without mods! For stability testing, I ran the card on an open-air test bench with its stock cooler after the soldering and BIOS flash, using a series of stress tests like FurMark and extended gaming sessions to monitor for artifacts, thermal throttling, or power delivery issues. If you’re planning something similar, I’d recommend keeping a log of your voltage and clock readings during those bench tests before finalizing your loop—it really helps pinpoint any instability early on. I’d love to hear how your own project turned out or if you have any other questions as you plan your next build.

Have you run any benchmarks to see the performance delta under that massive triple-radiator loop?
I totally get what you mean about the soldering challenge—adding that second power connector was indeed a meticulous process. The dual power mod, combined with the Matrix BIOS, unlocked significant headroom, allowing for a sustained power draw that pushed my benchmarks about 15% higher in synthetic tests like Port Royal compared to the stock single-connector setup under the same cooling. If you’re curious about the specific voltage and thermal data from those runs, I can pull up the charts; just let me know what benchmarks you’d like to see compared.
Wow, the idea of soldering a second power connector onto the 5090 is next-level dedication—I can only imagine the performance headroom that unlocks. My own water-cooling project last year was stressful enough just with standard parts, so seeing your custom 3D-printed cable management solutions is genuinely inspiring. What kind of synthetic benchmarks are you seeing with that ASUS Matrix BIOS flash?
Thanks for the kind words—it’s great to connect with someone who understands the meticulous effort that goes into a custom loop! With the dual power and Matrix BIOS, I’m seeing Time Spy Extreme scores consistently above 42,000, which really showcases the extra headroom. If you’re curious about the specifics, I’d recommend checking out Igor’s Lab for deep dives on BIOS compatibility and power scaling. I’d love to hear how your own project evolves, so feel free to share an update when you can!
That dual power connector mod is wild—I’ve always been too nervous to attempt a soldering job like that on a flagship card. Your approach of combining it with a silent custom loop really resonates, as I’m currently planning a build where I want to ditch the GPU fan whine without sacrificing performance. What was the most challenging part of integrating all those 3D-printed cable management components?
Thanks for the kind words—it’s great to hear you’re also aiming for a silent, high-performance build. The trickiest part of integrating the 3D-printed cable guides was ensuring they didn’t interfere with the radiator or fan mounts, so I’d recommend dry-fitting everything in the case with the loop drained before finalizing any mounts. I’d love to see how your own project turns out, so feel free to share an update once you get started!
The card looks promising, but its potential shouldn’t be judged by appearance alone. You need a skilled electronics specialist with experience in similar modifications and access to a properly equipped lab.
Did you do the mod yourself? If there’s a guide, I’d love to learn what it takes.
This was not a DIY project. I hired a team of top-tier specialists, including well-known electronics engineers and overclockers, to handle the work. While I consulted with them throughout, I did not physically touch the PCB myself.
There was no existing guide. The team had to reverse-engineer the power delivery logic and develop the entire modification process from scratch. This isn’t something that can be taught in a tutorial.
I was under the impression you did this yourself. Did you send the card to them? How much time did it take in total, and what was the cost?
It took about a week and cost around $500.
Not bad! Thanks for the insight. If I feel more inclined, I’ll look for services that can do this.
That dual power connector mod is wild—I’ve always been too nervous to attempt soldering on a high-end card myself, but seeing it done here makes me wonder about the actual power draw under load. My own water-cooling project last year was all about noise reduction too, though I only managed a single 360mm radiator; your triple 420mm setup must make it practically inaudible even under stress. What kind of temperatures are you seeing on the GPU core with that Alphacool block and the extra power?
Thanks for sharing your own noise-reduction journey—a single 360mm radiator is a solid foundation, and I totally understand the hesitation about soldering. With the dual power mod and the Alphacool block, the GPU core stays remarkably cool, hovering around 48-52°C under sustained synthetic load, which really lets the card stretch its legs. If you’re curious about monitoring power draw for your own setup, I’d recommend using HWiNFO64 to log the GPU’s board power sensor—it’s a great way to see exactly what your system is doing. I’d love to hear what temperatures you’re achieving with your loop!
Wow, that’s an incredible level of modification—soldering on a second power connector and flashing a different BIOS is serious commitment. It really highlights how the stock card was a “robust foundation” just waiting for this treatment. My own water-cooling project felt daunting with just soft tubing, so seeing a build with three 420mm radiators and dual D5 pumps for near-silent operation is genuinely inspiring. What was the most challenging part of integrating all those custom 3D-printed components?
Thanks for the kind words—it’s great to hear that the approach to using the stock card as a foundation resonates, and your own soft tubing project is a fantastic start! The most challenging integration was actually ensuring the 3D-printed fan and pump mounts aligned perfectly with the radiators and case, which required several test prints and minor adjustments to tolerances. If you’re considering custom parts, I’d recommend starting with free software like Fusion 360 for personal use to model around your exact components. I’d love to hear how your own build progresses or if you have any more questions!
As someone who’s built a few custom loops, I’m really impressed by the decision to add a second power connector and flash a different BIOS—that’s serious dedication to pushing performance. My own system is loud under load, so the idea of combining that much power with three 420mm radiators for near-silent operation is incredibly appealing. It makes me wonder, how are the pump and fan curves configured to balance that acoustic goal with the thermal demands of the 9950X3D and the modded GPU?
Thanks for the kind words—it’s great to connect with another custom loop builder who appreciates the balance of power and acoustics. To achieve that near-silent operation, I set the D5 pump to a fixed 40% speed, which provides plenty of flow without audible hum, and the fans are tuned to stay below 800 RPM until coolant hits 35°C, leveraging the massive radiator surface area to handle the combined heat of the 9950X3D and the modded GPU. If you’re looking to quiet your own build, I’d suggest starting with a fixed, low pump speed and using your coolant temperature as the primary control for fan curves—it really decouples noise from sudden component spikes. I’d love to hear how your tuning goes or what your current setup looks like!
That dual power connector mod is wild—it reminds me of the lengths we used to go to for extreme overclocking on older cards. Your choice of three 420mm radiators for a near-silent loop is particularly impressive, as I’ve struggled with balancing noise and cooling capacity in my own builds. It makes me want to revisit the fan curves on my single 360mm setup. What was the most challenging part of integrating all those custom 3D-printed components?
Thanks for the kind words—it’s true, those dual power mods really do bring back the spirit of old-school benching! The trickiest part of the 3D-printed integration was actually the alignment and mounting for the second power connector’s support bracket, as it needed to be perfectly flush with the PCB to avoid any stress. If you’re tuning your own fan curves, I’d suggest using a tool like Fan Control to create a curve based on your coolant temperature delta; it made a huge difference for me. I’d love to hear how your 360mm setup performs after some tweaks!
As someone who’s built a few custom loops, I’m really impressed by the decision to add a second power connector and flash a different BIOS—that’s next-level modding for pushing performance. My own system with a single 360mm radiator is already a project to keep quiet, so the idea of running three 420mm rads for near-silent operation with that hardware is incredible. What kind of load temperatures are you seeing on the GPU with that massive cooling capacity?
Thanks for the kind words—it’s great to connect with another custom loop builder who appreciates the balance of performance and silence. With the dual power mod and the massive radiator surface area, the GPU stabilizes around 45-48°C under sustained synthetic load, which really lets the overclock breathe. If you’re tuning for silence, I’d suggest focusing on fan curve tuning with a tool like Fan Control; it made a bigger difference for my noise floor than I expected. I’d love to hear what temperatures you’re hitting with your 360mm setup.
As someone who’s built a few custom loops, I’m really impressed by the decision to add a second power connector and flash a different BIOS—that takes some serious confidence. My own system is loud under load, so the idea of combining that much potential overclocking headroom with a silent triple-420mm setup is the dream. What kind of power draw and temperatures are you seeing with the Matrix BIOS under a sustained load?
Thanks for the kind words—it’s great to connect with another custom loop builder who appreciates the balance of pushing hardware while chasing silence. With the Matrix BIOS and dual power, the card pulls around 600-620 watts in sustained synthetic loads, yet the triple 420mm rads keep the GPU core under 55°C with the fans at a near-silent 800 RPM. If you’re looking to quiet your own build, I’d recommend trying a fan curve locked to your coolant temperature instead of component temps; it really smooths out noise spikes. I’d love to hear what you’re running—feel free to share your setup or any tweaks you’ve tried!

Thanks for the kind words—it’s true, those older modding days really set the stage for projects like this dual-power setup. The most challenging part of the 3D-printed integration was actually designing and test-fitting the custom fan shrouds and reservoir brackets to ensure they didn’t interfere with the massive radiators or the card’s new power layout. If you’re tweaking your own fan curves, I’d suggest using a water temperature sensor to guide them, as it creates a much more stable and quiet loop than tying fans to CPU or GPU temps alone. I’d love to hear how your 360mm setup performs after some adjustments!
As someone who’s built a few custom loops, I’m really impressed by the decision to add a second power connector and flash a different BIOS—that takes some serious confidence. My own attempts at modding have been much more conservative, usually just focusing on undervolting for silence. Seeing your setup with three 420mm radiators makes me wonder how you manage the overall system flow rate and fan curves to achieve that near-silent goal?
Thanks for the kind words—undervolting for silence is a smart approach and a great foundation. To balance flow and silence with three radiators, I use a high-flow D5 pump running around 60% and set a flat, low fan curve until the coolant hits 35°C, letting the massive radiator surface area do the work passively. If you’re tuning your own loop, I’d suggest focusing on that coolant temperature as your control point; it really simplifies managing noise versus performance. I’d love to hear how your own build progresses or what fan profile you settle on.
That dual power connector mod is wild—I remember how tricky it was just to solder a simple fan header without bridging pins, so I can only imagine the precision needed for something like that. Your approach with three 420mm radiators for near-silent operation really speaks to me, as I’ve been planning a quiet build myself but was worried about thermal headroom. What was the most challenging part of integrating all those custom 3D-printed components into the loop?
Thanks for sharing your own soldering experience—it really is a delicate process, and aligning those tiny pins on the power connector was definitely the most nerve-wracking step. The biggest challenge with the 3D-printed parts was ensuring leak-proof seals at the custom terminal block, which required multiple test fits and adjusting the print tolerances in the CAD model. If you’re planning a quiet build, I’d recommend starting with a single thick 420mm radiator to gauge your noise and thermal baseline—feel free to share your progress once you get started!

My own system is loud under load, so the idea of combining that much power with three 420mm radiators for near-silent operation is a dream goal. What kind of performance uplift did you see after the BIOS flash and power mod?
Thanks for the kind words—it’s great to connect with another custom loop builder who understands the pursuit of both power and silence. The dual power mod and Matrix BIOS flash unlocked a significant uplift, allowing sustained boosts well above stock, which the triple 420mm radiators then quietly tamed. If you’re aiming to quiet your own build, I’d suggest focusing on radiator surface area and low-static-pressure fans like the TOUGHFANs, as they excel in low-noise scenarios. I’d love to hear how your own project evolves, so feel free to share an update on your progress!

It makes me want to revisit the fan curves on my single 360mm setup. What was the most challenging part of integrating all those custom 3D-printed components?
Thanks for the kind words—balancing noise and cooling with a single 360mm rad is a real challenge, so I totally get where you’re coming from. The trickiest part of the 3D-printed integration was actually designing and test-fitting the custom fan shrouds that direct airflow through the stacked radiators, as even a millimeter of misalignment would cause turbulence and noise. If you’re tweaking your fan curves, I’d suggest using a water temperature sensor to tie fan speed directly to coolant temp rather than CPU/GPU readings for a much smoother and quieter result. I’d love to hear how your optimization goes or if you have any other questions about the build!
That dual power connector mod is wild—I remember how nerve-wracking it was just to re-paste my old 3080, so I can’t imagine the precision needed for a soldering job like that. Your choice of three 420mm radiators for a near-silent build really speaks to my own struggle with balancing noise and thermals in my SFF setup. What kind of load temperatures are you seeing on the GPU with that massive cooling capacity?
I totally get that nervous feeling—re-pasting a GPU is a big step, and the dual power mod did require some very steady hands! With this loop, the 5090 settles around 45-48°C under sustained synthetic load, which lets the fans run incredibly slow and quiet. If you’re balancing noise and thermals in a smaller space, focusing on radiator surface area and static pressure fans can make a huge difference—I’d be curious to hear what you’re working with in your SFF build.

Thanks for the kind words—it’s true, those older extreme overclocking mods were a real inspiration for tackling the dual power on this card. The trickiest part of the 3D-printed integration was actually designing and test-fitting the custom fan shrouds to ensure perfect alignment with the radiators and case, which took several prototype iterations. If you’re tweaking your own fan curves, I’d suggest using a thermal camera or even just a simple infrared thermometer to identify any hidden hotspots on your PCB or VRMs that might need more targeted airflow. I’d love to hear how your 360mm setup performs after some adjustments!
This build is incredibly clean.
Thank you! That means a lot. The goal was always to achieve maximum power while maintaining a clean, minimal aesthetic.
I was able to get it to pull 763 watts on the stock BIOS with just some software tweaks, all through the 12VHPWR connector.
Could you clarify if the two connectors split the current load equally as power draw increases and decreases? I may have missed this detail in the pictures or comments. This is an incredible build.
Thanks. That’s the key question.
Currently, I can’t monitor the exact power split in software because the sensor combines everything into a single reading. I’m waiting on Aquacomputer Ampinels, which are hardware sensors, to verify this properly. Once I can physically measure the draw per connector, I’ll have the definitive data.
This is an impressive build, and the final result looks absolutely stunning.
Coincidentally, I just got an Aorus 5090 myself. While tearing it down, I was wondering if it would be possible to solder an additional power connector in that exact spot.
Now we have a clearer picture of what was done.
Does power balancing work between the two 12VHPWR connectors? Can you monitor telemetry for both in HWiNFO or your monitoring software? My 4090 Gaming OC also has an empty spot, and I’ve considered doing this, so I’m curious. Thanks.
Great build, by the way.
Thank you. The software monitoring shows it as a single combined value, but physically, the cable temperatures and voltage stability confirm the load balancing is working well.
Regarding the RTX 4090, this is a known modification for that card. However, please double-check your specific PCB revision to ensure all the necessary supporting components, like shunts and capacitors, are populated before attempting any soldering.
Is that the Havit HS 420?
It’s impressive that this works, and it’s somewhat ironic that despite drawing over 800 watts, this setup is likely safer for the power connectors than a stock card.
Agreed, but we need more testing. A lot more. And Ampinel!
It’s taking a while longer. I’m waiting anxiously for that first batch.
I need help with the VBIOS on my MSI 5090. The physical switch on the PCB toggles between silent and performance modes by adjusting wattage and fan speed. Unfortunately, it’s a cheap part that was faulty from the start, and now it has fallen off. As a result, my 5090 fails the boot-up test and causes the PC to shut down.
I understand your frustration. If I were in your position, I would insist that MSI provide a prepaid shipping label, as a switch falling off is clearly a manufacturing defect.
Do not attempt to solder it yourself. Any sign of repair or flux near the vBIOS switch will void the warranty immediately.
I’ll have to disagree, but I appreciate the input.
I want to initiate an RMA, but MSI requires me to pay for shipping to them. Insuring an RTX 5090 makes this a significant expense. I’m wondering if I can instead provide a photo as proof, or if I could attempt a repair myself—like soldering for a stable performance mode using flux on the board.
What are the fans on the RAM?
Thermalright TL-B6B.
How are the additional components mounted?
Custom support bracket.
Excellent work! I’ve been anticipating this mod ever since noticing the second power connector’s traces in TechPowerUp’s teardowns.
Thanks! Seeing the traces is one thing, but actually soldering it and hoping the internal power planes are connected was a tense moment. I’m glad to confirm for the community that they are functional.
You can verify the planes are connected with a multimeter in seconds.
This has been a common mod for Gigabyte cards since the 40-series, but I believe you’re among the first to publicly document it on the 50-series.
Hai dovuto modificare il waterblock? Perché hai scelto quello della Aorus Master? È compatibile con lo spazio per il secondo connettore di alimentazione?
The water block is designed to accept fittings on any side. Aorus Master boards share a unified design, and the block is made to be universal for that series. I didn’t fully understand your third question.
Did the water block already accommodate the second power connector, or did you need to modify the acrylic? I’m working on a similar project with an AORUS XTREME in Astral White—I purchased it after having the black version specifically for the ASUS Matrix BIOS mod. Your solution intrigued me, and I wanted to understand the work involved. I gathered some details from reading the rest of the thread.
What case are you using?
Haven’t seen a 420.
Thanks for sharing.
Looks neat. What’s your flow rate? Regarding the 800W BIOS, I tried it and it does make the 12VHPWR connector run warmer. I rigged a 90-degree adapter with a temperature probe, and the temp reached 60°C even with a fan blowing on it at very high speed (5000 RPM). With the normal BIOS, it hovers around 55°C with a relaxed fan speed.
Also, I’d suggest using a putty with PTM. It really helps with memory temperatures.
Interesting. Where did you place the probe?
Based on the other replies, I still advise against using an adapter. You should install a second thermistor between the +12V pins.
I placed thermal putty between the heat sink and the adapter’s PCB, replacing the original pad to ensure proper contact at the soldered 12VHPWR connector.
In my testing, the flow rate is around 100-120 L/h. I run the pumps at 20-30% for complete silence. With three radiators, the loop has sufficient thermal mass to keep temperatures in check.
The cable heat issue is precisely why I performed the modification. Pushing 800W through a single connector is concerning (over 66 Amps). By using two connectors, the load is split to roughly 33 Amps each. They now remain completely cool to the touch without any active cooling or fans directed at them, which was the primary reason for soldering on the second port.
Regarding putty, I’ve heard positive feedback, but I prefer the clean application of high-end thermal pads like the Invictus IV. So far, my memory temperatures are excellent.
How does the Invictus IV compare to the Gelid Ultimate? I have the Gelid on hand, but if the Invictus is significantly better, I might switch to it since my card is still out of the build.
From what I understand, Gelid Ultimate pads are rated at 15 W/mK, while Invictus claims around 24 W/mK. The Invictus pads also felt much softer to me. Since softness is crucial for ensuring good core contact with water blocks, I would recommend using them.
Thanks for the info. I noticed the 3mm Gelids were a bit firmer than the pads that came with the Alphacool block. I’ll likely keep the 1mm pads on the front for now, but I’ll pick up the Gelids anyway in case I change my mind. Now I just need to find a retailer that sells them in the U.S.
Adding a 90-degree adapter will likely make the issue worse. Instead of generating heat at a single connection point, you’ll now have two.
It’s debatable. The adapter is a 2oz board with a heatsink, which appears to transfer heat adequately, and the fan does help keep it cool. I recall derbauer noting that his adapter failed when used with a water-cooled card, where the airflow from the heatsink’s fan was absent.
The real question is identifying the weak point.
The fan will definitely help, but it would still be better to avoid the adapter. Fewer connections mean less chance of current imbalances, which is what really causes problems.
The adapter does balance the current, as all pins are joined on the circuit board. If a failure occurs, it should happen at the cable, not the card, or potentially on the PSU side.
I’ve also added a temperature probe to the adapter to monitor heat. So far, it hasn’t exceeded 56°C while pulling close to 600W.
That’s the opposite of balancing; it’s actually the worst thing the adapter could do.
By joining all the pins, it renders the monitoring on the Astral useless. This makes it even worse, even if you have that card.
Not the Astral, but why is it worse? Isn’t that the issue that causes melting?
The issue is that all the pins are joined together, which is what you described the adapter as doing.
The issue identified by der Bauer or GN is that some pins can transfer more current than others, exceeding the 8-amp specification.
If the adapter balances the load on the card side, then any imbalance would occur on the female side of the adapter or at the PSU. This would at least prevent damage to the more expensive component, unless I’m misunderstanding the situation.
I understand the connector issue and what you’re trying to explain, but something is missing. You mention the adapter does load balancing, but how? Simply joining the pins isn’t load balancing.
I get that a failure between the adapter and the PSU is less severe than at the GPU, since those parts are cheaper. If the adapter acted as a sacrificial component, that would make some sense.
However, there’s no guarantee that would happen. Current imbalances on each pin aren’t caused by the cables themselves, but by the connection points—whether from user error, slight manufacturing defects, dust, vibration over time, or other factors. Since there’s still a connection point between the adapter and the GPU, the potential for an imbalance and problem remains.
The only way the adapter could be truly beneficial is if it kept the power poles separated instead of combining them, and monitored each one as they enter the GPU. It could then include an alarm or even cut power if it detects an imbalance. There’s no real way to “balance” the load—only to monitor it.
This looks great until you encounter an issue and need to drain the coolant—a costly setup.
That’s a common misconception, but a valid question. Regular fluid changes every 6 to 12 months are essential to prevent ionization and component damage. This is proactive maintenance, not a problem.
The process is straightforward for this build, and I’ve done it twice. First, place the case into the basin. Then, secure the custom drain adapter to the bottom port with a small drop of silicone. Open the top plug, bleed the air via the flow sensor valve, and attach a hose to the top port to apply low-pressure air, which fully evacuates the loop.
The entire process is clean and takes only minutes. I do admire your confidence in calling it a “money burn configuration” without knowing the actual maintenance procedure.
That’s still high maintenance for a PC.
Excellent build—it’s both performance-focused and visually appealing.
Thank you. That was the main idea. I wanted a reliable machine that’s comfortable for gaming but also allows for overclocking when I choose to.
I appreciate near-blackout builds, and this one is exceptionally clean with great style.
I also really like the “because I can” spirit behind the 5090.
Thanks! Exactly. It’s not just “because I can,” but also for science.
That’s a beautiful cat. We think our girl might be part Burmese—she’s solid but has a soft coat.
I’ve had to RMA every motherboard except this one so far due to various issues. The biggest problem is that MSI keeps sending back used boards.
My first board was returned with all the plastic films still on it because the PCIe x4 slot wouldn’t run at x4 speeds, even with the shared M.2 slot empty and correctly set in the BIOS. The board I got back was clearly used, with the dynamic display badly scratched and other signs of wear.
The most telling part is that every replacement board has had a different brand’s socket protector. The latest one even came with an Asus protector. Needless to say, I’m not impressed with MSI’s warranty handling, especially for such an expensive product.
I do have a few questions now:
How new is your board? Was it purchased recently, and do you know the manufacturing date?
Are you using any other M.2 drives? I’m currently running five 4TB drives (two Corsair, three WD). This setup has been consistent from the beginning. My first board, bought at launch, booted reliably, but I didn’t keep it long.
I’m considering sending this one back as well, since it shouldn’t have these issues. However, from what I’ve observed over the past year dealing with this, it seems to be a broader AMD/MSI problem. If they actually send me a board that works properly this time, I’ll be satisfied.
That is an unacceptable situation, especially for a board in the Godlike price tier. Sending back used or modified boards with different socket protectors is insulting. I sympathize with your trouble.
My own board was purchased about five months ago and is likely from an early batch. I’m running two M.2 drives—a Gen5 for the OS and a Gen4 for storage—and both negotiated their full speeds on the first boot without the issues you described.
If you’ve gone through five boards with the same training problem, it points to a systemic platform or early batch issue that won’t be fixed by a simple swap. I hope MSI addresses this officially. Good luck.
To help troubleshoot, how many total M.2 drives are you using and in which slots? Are you using any other PCIe expansion cards? Have you manually checked the PCIe bifurcation settings in the BIOS to ensure the GPU slot is running at x16?
You are correct about the cat being a purebred European Burmese. I have a dedicated photo log in my profile if you’d like to see more pictures.
I’m using all four M.2 slots and the PCIe x4 slot with a PCIe to M.2 card. Slots 1 and 2 have identical Gen 5 Corsair drives, and slots 3 through 5 have identical Gen 4 WD drives.
My only PCIe card is the RTX 5090 in Slot 1 (I previously had a 4070 Ti). Slot 2 is intentionally left empty.
The BIOS is where my troubleshooting began. Since I don’t need the USB4 slots, I set the second M.2 slot to full x4 bandwidth, which works as expected. The x4 slot with my M.2 drive is also set to full x4, which disables M.2 slot 4. I’ve tried both “auto” and manual Gen5/Gen4 settings with no change.
On my first board, the x4 slot would only run at x2 speeds even with the linked M.2 slot empty. The second board’s first PCIe slot was limited to x8. The third board couldn’t run EXPO profiles and had frequent issues with Dynamic Display, which was a common problem with this specific model. I only had the fourth board for a day before finding an issue and returning it.
After spotting the issue with the second board, I started thoroughly checking each one for failures and found problems with all of them. Most had the M.2 issue to some degree, but it was usually resolved after a single boot.
This board has another quirk: the PCIe x4 slot occasionally negotiates at x2 speeds, even when the first M.2 slot is working correctly.
Since your board is about five months old, it might be from a new batch. They were out of stock at many retailers until about four months ago. Your information is invaluable, as most reports of these issues are from people who bought their boards at launch up to seven months ago. Given that they’ve since launched the Godlike-X, they likely know what was wrong and have fixed it in production.
Thanks again for the info. I’ll check out the cat pictures!
Thank you for the detailed log. This is an impressive and extreme configuration.
The board may be running out of available bandwidth to train all devices at their maximum speed simultaneously. This might not be a flaw, but rather a limitation of the board’s design—either hardware or BIOS—that prevents it from handling that specific load, regardless of the stated specifications.
I would recommend stripping the system down to the bare minimum, then adding components back one at a time while checking the boot behavior after each addition.
I suspected that might be the case. Based on information from Reddit and the MSI forums, most people are experiencing this issue with a single drive.
The general consensus for a workaround is to use the second M.2 slot.
I still have some A/B testing to do with a different processor and different M.2 drives I recently purchased to see if anything else is contributing. From what I could find, this also appears to be partly an AMD-related issue.
Since you’re running a 9950X3D without any problems, I’m starting to wonder if it’s a board-CPU compatibility issue that makes the problem more apparent.
I’m running a 9800X3D, which is probably a very common combination, and that might be a factor.
Also, the drive in my first M.2 slot has a power-on count of 592. I’ve likely booted and checked the transfer mode closer to 475 times, as I have DiskInfo64 set to launch on startup.
The fact that your system sets the transfer mode properly and maintains correct read speeds is invaluable for testing. One thread I found on this issue had users reporting the transfer mode displayed correctly, but when tested, the read/write speeds were consistent with reduced bandwidth.
I’m confused. Were there provisions for a second power connector, or did the shop find a spot close enough to the necessary pins to make it work? It also looks like the 12VHPWR connector was removed entirely. This is really cool, but I need more details.
This is a classic case of **PCB reuse**. Manufacturers often design a single ‘master PCB’ to cover multiple models, such as standard cards with top power connectors or workstation cards with rear connectors.
Because of this, the traces and solder pads for the second power connector were already physically present on the board—they were simply left unpopulated at the factory.
It makes me wonder why manufacturers don’t capitalize on the general consensus that the 12VHPWR connector is problematic. They could offer a factory solution like yours. I’m sure many people would choose that card over others for that reason alone.
Nvidia likely prevents manufacturers from selling cards with two power connectors because it would highlight the limitations of the 12VHPWR plug.
Perhaps they intend to sell “elite” cards at double the price by adding just one more plastic connector.
Consider replacing the thick VRAM thermal pads with copper shims and PTM 7950.
Technically yes, but the tolerance window is so tight that manual work lacks the necessary precision. We’re talking about a margin of error measured in microns. Without industrial tools, hitting that window reliably is nearly impossible. Doing it by hand would almost certainly compromise core contact and risk overheating the chip. For a home assembly, using soft pads is simply the safer approach.
The copper mod isn’t worth the effort. I tried it on an air-cooled 3080 TUF and saw no benefit. On a different 3080 TUF, I simply replaced the thermal pads and used PTM7950 on the core, achieving the same temperatures.
Is this from Russia?
Sometimes, you just have to admire the dedication.
Have you measured the power draw from each connector?
Is it nice to be rich?
It’s great to see the result of hard work, regardless of the price. Honestly, earning money is often easier than engineering a complex, reliable system, and it’s certainly easier than mastering tact and politeness.
I have the same soft tubing blackout build in this case, just with more modest components. I don’t know why, but it always feels like a missed opportunity when people get this case and don’t install 3×420 radiators. You, my friend, have done it right.
I completely agree. Using less than three 420mm radiators in this chassis feels almost criminal, as it’s clearly designed to be a beast.
The potential is incredible, and the case’s name itself hints at its intended purpose. Thanks for the kind words.
It looks like your cat is marking its territory by spraying your PC.
Beautiful cat.
Красивый сбор.
How did you figure out how to add the extra power connector?
I have experience modding and flashing 40-series cards, so I understood the approach. I also consulted with some respected figures in the extreme overclocking community to validate the PCB layout and finalize the implementation details.
That’s impressive work. As an electrical engineer, I used to perform hardware BIOS mods on 970s to unlock the power limit. I’d be very interested to learn more about your process.
Respect to a fellow veteran.
For the physical soldering on this project, I had a professional electronics lab handle it to guarantee factory-level quality.
On the BIOS and software side, I typically flash standard cards myself using guides from sources like Guru3D. However, for a flagship card like this, I prefer to leave it to professionals who have hardware programmers on standby. It’s a good way to keep the process stress-free.
Reading this thread and pretending to understand what’s happening.
This is the kind of helpful community that makes Reddit great. Feel free to ask any questions; people here are genuinely willing to assist.
Looks great—excellent work. Enjoy it!
The technician is inspecting the build quality. I love your build.
Thank you! She is the regular Chief Quality Control Officer. Nothing gets powered on without her final sniff of approval.
How many boots does your motherboard need to properly negotiate Gen5 x4 speeds for the first M.2 slot?
I’ve had five different Godlike boards, and every single one has had issues negotiating the correct speeds on boot.
My current board seems especially prone to dropping to Gen1 x1 (or sometimes odd speeds like Gen3/4 x1) and can take up to four full restarts before that first slot runs at Gen5 x4.
Also, we need more pictures of the cat.
What case is this, and more importantly, will it fit an SSI-EEB motherboard? Great-looking build.
The case is a Havn 420. It’s excellent for housing three 420mm radiators, but I’m uncertain if its form factor will suit your specific build.
Thanks. That’s a great case and build, but it only supports up to E-ATX, so it won’t work as a replacement for my Phanteks Enthoo.
I recently got an Enthoo Primo for $50 AUD and am fitting 1440x120mm of radiator inside it, including an EK XE 480mm, two XE 240mm, and Alphacool Monsta 360mm and 120mm rads. Other than a change of scenery or perhaps an even more monstrous loop, I’m not sure why you’d need to replace that case.
Do you have any photos of the build? I’d love to see it.
I haven’t set it up yet. I’m currently building in a Lian Li O11D Mini V2, which has 1080x120mm of radiator space. I chose this case because if I sell my current rig to upgrade later, a more mainstream and popular case will likely be easier to sell.
The Enthoo is a masterfully designed case—spacious, solid, and easy to work in. That’s a great choice. For other options, consider the Thermaltake AX500, which supports dual 420mm radiators and BTF motherboards without any modification. If you prefer a less conservative design, look at the Fractal Torrent or the Raijintek Zofos Ultra. For a dedicated gaming setup, the Cooler Master HAF 700 is also excellent.
The Enthoo Pro 2 is a great server case. It’s a rock-solid beast with everything you need, though the interior aesthetics are very functional rather than flashy. The exterior is clean.
I also had a Corsair 9000D, which I loved.
I’ve used Thermaltake cases since my first build in the early 2000s. I skipped the AX500 because it felt too similar to the 9000D, but I might reconsider.
I wasn’t aware of the Zofos Ultra. It looks impressive, but it seems to only support up to E-ATX. I may consider it for a future build.
Thanks for the recommendations.
It’s a rare pleasure to meet a fellow veteran of water cooling and heavy hardware. The 900D is a legend, with room for everything you could want.
It’s a shame the AX500 didn’t work out, but I agree it has a similar spirit to the 900D.
Regarding the Zofos Ultra: the specs I saw listed support for SSI-EEB. Your specific motherboard might be wider than the standard EEB specification. In any case, sticking with the Enthoo was a great choice—it’s tough to beat.
The 900D is a classic case with plenty of space for almost any build. If you’re looking at the Zofos Ultra, just verify its dimensions against your motherboard, as it could be a tight fit. The Enthoo is a reliable choice, but it’s also worth exploring newer alternatives.
I’m surprised no one has mentioned this yet. All your fans are set to exhaust. Are you planning to run the system without side or front panels? I suggest flipping some fans around or getting reverse-blade models.
Nice work.
Looks killer. The memory module fans are a great touch.
ZMT tubing and quick-disconnects are the hallmark of a true PC enthusiast. Is that a crossflow radiator on the back wall?
I completely agree that reliability is the most important factor.
To clarify the radiator setup: the X-Flow is the top radiator, which helps with tube routing. The side or rear radiator is the HWLabs Nemesis GTX, and the thick Monsta is installed at the bottom.
My motherboard includes additional power connectors—one for PCIe stability and another dedicated to 60W USB-PD charging—and I have both connected.
However, the PCIe slot itself is only rated for about 75W maximum. I don’t see a way to push over 150W through the slot pins without risking damage to the traces.
Have you checked your motherboard manual? Many people seem to overlook the 8-pin PCIe power connector on the board, which can provide an additional 150 watts to your GPU.
The connector is located just below the two right-angle USB ports on the motherboard.
You can test this by plugging an 8-pin cable into that connector and removing the one you modded onto your card. This should allow you to draw up to 800 watts.
On my X870E Carbon WiFi, I connected an extra 8-pin PCIe cable to my RTX 5090 running the Matrix BIOS, and I’m able to pull the full 800 watts this way.
Could you point to the specific section in the manual that states a single x16 slot can deliver 150W to the GPU? To my knowledge, the PCI-SIG specification limits the physical slot to 75W. Even if the motherboard’s rail can supply more, the GPU isn’t designed to handle 150W through the slot pins, which could risk melting them.
In my experience, the practical result is clear: using one power connector causes the cable to overheat, while using two keeps them cool.
It wouldn’t melt. The PCI-SIG specifications are designed with tolerances in mind, which accounts for manufacturers cutting costs.
Using HWiNFO64, you can check the “GPU PCIe +12V Input Power” reading. Is it showing around 150W?
I can’t see the image you’ve linked, so I’m unable to rewrite the comment. If you can provide the text from the comment, I’ll be happy to rewrite it for you.
I responded to the person claiming the slot can supply 150W.
I’m here for the cat. Is it a Burmese?
Good eye! Yes, she is a European Burmese. Honestly, it’s the best purchase I’ve ever made.
Your landlord’s female Burmese cat looks just like yours. I love them both; she’s very cheeky.
That is true.
Is it watercooled as well?
She is an unpredictable heating element who loves to lie on top of the radiator.
Is the cat urinating on it?
The absence of RGB and acrylic tubing is an automatic win in my book.
Is it possible to add a second 12-pin power connector to a 4090 Master?
I considered adding a second power connector myself, but I don’t have a hot air station for the job.
