I'm moving from an Intel i9-12900K and RTX 3080 FTW3 to a Ryzen 7 9800X3D, RTX 5080, and ASUS ROG STRIX X870-A Gaming WiFi motherboard. I'd like to reuse my Corsair Dominator DDR5 2x16GB 5200 RAM, two 1TB Samsung 980 PRO NVMe drives, and ASUS ROG STRIX 1000W modular power supply. Do I really need to perform a clean Windows installation on my main drive, or can I try booting the existing installation and install the new AMD drivers? Will my secondary drive and the files on it work normally, and should I connect it only after Windows is installed? Also, the RAM is labeled for XMP rather than EXPO—will it work properly on AMD—and is the included 16-pin graphics card adapter safe to use with my PSU? I have important documents on the secondary drive and want to avoid accidentally losing anything.

Back up the important files before changing anything. A motherboard swap can occasionally cause boot or partition problems, so having an external or cloud copy is the safest move. You can try booting the existing Windows installation first; Windows often detects the new hardware and starts normally after installing the AMD chipset and other motherboard drivers. A clean install is good practice, but it isn’t always required. Make sure your Windows license is linked to your Microsoft account, and check whether BitLocker is enabled before starting.
You can attempt the hardware swap with the current Windows drive, remove or replace the old Intel-related drivers, and install the AMD chipset drivers after the first boot. If Windows behaves badly, a clean installation is the fallback. The 1000W supply should have enough capacity, but use the graphics card’s included 16-pin adapter only with the correct separate PCIe power cables from the modular PSU—never reuse modular cables from a different power supply. Seat the connector fully and avoid sharply bending the cable near the plug.
The DDR5 kit should generally work, although XMP is an Intel memory profile and may not be as effortless as EXPO on AMD. Start at the motherboard’s default memory settings, then try enabling the XMP profile if everything is stable. If you get crashes or boot loops, lower the speed or leave the profile disabled. Also confirm that you have the correct cooler mounting hardware, fresh thermal paste, and the AMD chipset drivers ready before assembling the system.
Your secondary NVMe drive should be fine to reuse. Files such as documents and media will remain accessible, but programs installed there may need to be reinstalled or pointed back to their existing folders after a fresh Windows installation. For maximum safety, install or connect only the intended OS drive while installing Windows, then add the secondary drive afterward so there’s no chance of selecting the wrong disk.
