The Corsair RM850x would be sufficient, though it isn't brand new.
Replace the GPU, refresh the MB BIOS—it’s an outdated MB for a brand new GPU. Reinstall the Nvidia App. Avoid using the .16 driver; use the .24 hotfix here: https://nvidia.custhelp.com/app/answers/.../a_id/5624. My 5080 wasn’t recognized until drivers were installed. I also had integrated graphics, which allowed booting. (You might need to connect the HDMI DP cable to the MB instead of the 5080 until drivers are applied.)
