What should I change in this RTX 5080 gaming PC build?

The parts are generally compatible, but enable the memory profile in the firmware after assembly so the RAM runs at its advertised speed. It’s also worth updating the motherboard firmware if necessary and checking the graphics card’s power cable routing and clearance in the case. The integrated graphics on the processor can be useful for diagnostics, although the motherboard’s video outputs will only work when the CPU’s graphics are enabled and connected properly.

Since the monitor, graphics card, and power supply are already owned, this budget is much more realistic. The overall platform makes sense for a high-end gaming system, and the 9800X3D is a strong match for a 5080. Just double-check current pricing before ordering: the listed DDR5-4800 kit and NVMe drive look unusually expensive, so faster DDR5-6000 memory with a reasonable latency rating and a better-priced 2TB SSD would likely save a substantial amount without hurting performance.

The monitor being already purchased is the key detail here. A 1000W supply should be plenty for this setup, and choosing a motherboard with Wi-Fi and integrated graphics addresses the troubleshooting concerns from the previous build. You could also consider the regular Fractal North instead of the North XL unless you specifically need the extra room; the 9800X3D and a large air cooler should fit in the smaller case.
