I’d love to hear what kind of cooling setup you’re considering if you decide to upgrade.

  22. I’m already thinking about how far I can push my home circuit beyond its spec. An 800w draw is intense. I love this; please give us more products like the ROG Matrix GeForce RTX 5090.

  23. If your budget allows for it, spending on your hobby is reasonable. My wife enjoys travel, and I enjoy gaming. We reached a fair compromise: I invested in a $20,000 PC setup, and she took a three-week vacation to Jamaica.

  24. I’m not sure if this is aimed at me, but it’s true that some people can’t afford or choose not to spend on things others will. I personally spend on cosmetics because I enjoy customizing my character’s appearance. I support cosmetic microtransactions, as they’re optional and don’t affect gameplay.

  25. While prices have decreased, I still can’t justify spending $2500 on a GPU. It’s simply beyond my budget. I nearly bought a 5080FE from Nvidia’s website when they were in stock, but the 16GB of VRAM is a deal breaker for me. Since I already have 16GB, any upgrade needs to improve both performance and capacity. I’m waiting for a 5080 Super to make the move.

  26. It’s listed as supporting that wattage, but I highly doubt it can actually power 600 watts. I don’t believe the motherboard connector itself is even capable of supplying that much power to a GPU.

  27. Even with the cards I own, I can confidently say they are not worth the cost. Despite being the best on the market, they are simply too expensive, especially for anyone who paid scalper prices.

    1. It offers a bit more performance and splits power delivery between the 12VHPWR cable and the BTF connection. The design is also a factor, though personally, I’m not a fan of the look.

          1. The 4090 is a 450W card, and we still regularly see new cases of failures, including with the 12VHPWR connector. In my opinion, that connector should be legally banned as an electrical fire hazard.

            I’m serious. We’re essentially waiting for a fatal incident to occur before anything is done. Tragically, this is how it always seems to go.

    1. To provide the full 800 watts of power, you’ll need two 12VHPWR cables. To my knowledge, these are only available on 1600-watt power supplies, like the MEG model I have and a few others.

  28. It’s similar to any other hobby. Some people spend money on cars or motorcycles, while I prefer to stay home and enjoy my interests.

    Consider someone with a $1,500 monthly car payment. Is it the most practical choice? No. Could they achieve the same function with a $400 payment? Yes.

    I evaluate everything through a cost-benefit lens. Ultimately, it depends on how much disposable income you have, which determines what that initial cost represents to you.

          1. I’d estimate it draws 600 watts from the BTF connector and 300 watts from the standard power connector.

          2. Since BTF cards already show no performance loss when used exclusively with BTF, I would assume BTF can handle 600 watts or even more.

          1. It might be possible. I’ve seen a video of people using the ASUS BIOS on a non-ASUS PCB. I can try to find it for you when I get home.

          2. The BIOS is provided by ASUS exclusively to select individuals, typically competition overclockers. It has not been leaked yet.

    1. The liquid metal cooling should make it run a bit cooler than the standard fan-cooled Astral RTX 5090, and it uses an 800W power draw instead of the Astral fan’s 650W. The major difference, however, is the BTF motherboard connector and 12v-6×2 connector, which should contribute to a more stable GPU over its lifetime.

      Realistically, the main appeal is the design. It will likely cost about the same as the Astral and be cheaper than the Astral LC, so the Astral LC is still the best option in my opinion.

    1. The 450W power draw for the 4090 is reasonable when you consider the performance of its 128 SMs under full load in tasks like machine learning. The same logic applies to the RTX 5090, which actually uses less power per SM.

      The issue is that for gaming, both the 4090 and 5090 have more SMs than are typically needed, so they often idle while the graphics processing clusters try to keep them busy.

      Historically, Nvidia’s flagship GPUs also draw significant power when pushed. The 3090 could easily reach 500W. The 2080 Ti, 980 Ti, and 780 Ti could all have benefited from a 400W power limit. The 1080 Ti was more modest, but it was also a smaller flagship chip.

  29. If you’re spending $4,000 on a GPU, you might as well pay double for the RTX Pro 6000. It would provide a similar or greater performance uplift while using only 600W and still offering 96GB of VRAM.

  30. Yes, it was worth it. I purchased mine in March when they were unavailable elsewhere. I paid $4500 for an Astral LC model. With no Micro Centers nearby to camp out at, and Best Buy not carrying the LC variant, it was my only option. It was the final component I needed after being without a PC for a year following a lightning strike at my house.

    Ultimately, it was a win. Value is subjective and depends on your disposable income. I recognize my financial situation is better than most, and I don’t presume to know what’s best for everyone. For me, it was worth it. My $20,000 WFH/gaming office is now complete and gets daily use from my wife and me.

    I also understood that MSRP was never realistic. Based on experience, I knew prices wouldn’t meaningfully drop until close to or after the next generation’s release.

    1. How is that worth it? I don’t think that’s a win; you were played and exploited. There’s really no other way to put it. Paying that much over MSRP is just being taken advantage of.

      I could afford to pay $4500 for that card like you did, but I got one for a few hundred over MSRP instead by waiting a few months. You can try to justify it however you want, but it’s just not realistic. It’s okay to admit you were played, but are still happy you got the card and don’t mind the unnecessary loss of money. You have to be realistic.

      1. The current MSRP is $3,800, and they are still out of stock. Paying $700 more was an easy decision. I could have waited for them to come back in stock and saved $700, but that wasn’t a practical option.

        1. “Calling it a ‘no brainer’ means you’re willingly accepting exploitation. I don’t mind overpaying for things, but you should at least acknowledge that’s what you’re doing and that you’re being exploited.

          Also, these RTX 5090 cards are in stock everywhere now.”

          1. People who overpay are being exploited, and I’m well aware of it. In fact, I contribute to that exploitation by creating marketing campaigns that drive demand.

    1. Regardless of your budget, paying more than double a product’s price is never worth it. I paid above MSRP for my Astral, but I got my RTX 5090 FE at MSRP. Both are still overpriced.

  31. I don’t care about the price of these premium cards, as they’re obviously not for normal consumers. However, this design looks terrible. The 4090 Matrix looked amazing.

    1. It depends on your definition of affordable, as PC components are generally expensive. However, since you’re commenting on an RTX 5090, they are indeed more affordable now at $2,000-$2,500 compared to their previous price of over $3,000.

  32. Based on the image, this appears to be a render or concept, not an official product. The design is reminiscent of the previous ROG Matrix RTX 4090, but with a different shroud and fan configuration. I would wait for an official announcement from ASUS before taking this as a confirmed product.

  33. Based on the 800W promo, it seems they might actually include that high-wattage BIOS. If so, it could perform as well as the RTX 6000, albeit while consuming more power. It would be a beast. On a side note, it’s quite unattractive.
