B850M Motherboard Cost-Effectiveness Comparison: Which One Reigns Supreme?

📌 Quick Test Highlights
• Power Supply & Performance: Can it handle AMD’s 9950X3D?
• Expandability: Are the M.2 interfaces and PCIe slots enough for your needs?
• Overclocking Capability: How high can the memory go?

⚡ Power Supply & Performance Unleashed
Extreme Stress Testing with the 9950X3D
• GIGABYTE Aorus Mini-ICE: The undisputed MVP! 🔥 A R23 score of 44,400, with a steady power consumption of 225W and rock-solid voltage control—it’s all about aggressive performance release.
• MSI Mortar: Solid and dependable, scoring 43,500 points with a power draw of 220W.

Balanced tuning ensures no weak spots here.
• ASRock Taichi Black Storm: A prime example of poor optimization 💣 — despite a power surge to 240W, its score bottoms out at 42,500. BIOS issues confirmed as the culprit.
• Colorful Terminator: Budget-friendly dark horse 🐎 in the 800-yuan range! Scores 43,500 but has slightly higher power consumption (on par with the Black Storm).

Power Phases: ASUS ROG Strix DARE takes the crown with its robust 14+2+1 phase design (80A each), though its conservative tuning holds it back. All other motherboards manage to support the 9950X3D effectively.

🔌 Expandability Showdown
M.2 Interfaces
• MSI Mortar: Three M.2 slots—two blazing fast PCIe 5.0 and one half-speed PCIe 4.0. Kudos for the clever hidden-back design ✅.
• ASUS ROG Strix DARE: Three front-facing M.2 slots—1 PCIe 5.0 and 2 PCIe 4.0—but poor layout design ruins the experience ❌.
• GIGABYTE Vision Dual/Aorus Sapphire Pro: Only two M.2 slots, both PCIe 5.0.

PCIe Slots
• Mortar/Sapphire Pro: A PCIe 5.0 x16 primary slot paired with a PCIe 4.0 x4 secondary slot, perfectly balanced without conflicts.
• ROG Strix DARE: The secondary slot is essentially useless due to its x1 length, combined with a GPU-sinking design that discourages users with triple-slot cards 💔.

USB Ports
• ASUS ROG Strix DARE/GIGABYTE Aorus Gaming: Twelve USB ports, including a blazing-fast 20Gbps Type-C port.
• MSI Mortar: Nine USB ports (with a 20Gbps Type-C port)—high quality but slightly fewer than competitors.
• Colorful/Sapphire: Fewer ports and slower speeds, but hey, you’re paying less, so grit your teeth and bear it 🙈.

🚀 Overclocking & Memory Performance
EXPO Default Performance
• ASUS ROG Strix DARE: Lowest latency, yet gaming frame rates surprisingly lag behind the benchmarks 📉.
• ASRock Taichi Black Storm: Strong low-frequency overclocking, but collapses under EXPO [Facepalm].

Overclocking Potential
• MSI Mortar: Stably reaches 6200 C28, with fine-tuned parameters boosting gaming frame rates to top-tier levels (second only to the best).
• Colorful Terminator: A jaw-dropping 8200 C40 pass! However, small-parameter tweaking leads to crashes, but its value remains unmatched.
• Sapphire Nitro+: Skipped overclocking tests entirely, default performance is unremarkable, not recommended ❌.

📢 Summary
• High M.2 demands? → Go with Mortar.
• Limited budget? → Choose the Terminator.
• Want both aesthetics and performance? → Pick Ice Carving.
• Avoid at all costs? → Taichi Black Storm and Sapphire Nitro+ (unless they’re on clearance sales!).
