From there I type in my password and the desktop opens immediately. I read a post by a guy with a 3080 recently who seemed to be having problems with his 3080 in PCIe4 mode (with an x570 Master)--he resolved them by manually switching to PCIe3 mode--I very much doubt you will see any performance problems from doing that. Whereas AMD has been shipping PCIe4 GPUs for 18 months, these new nVidia GPUs have only now come to support PCIe4 themselves with the RTX 3k series. I feel that it's only a matter of time before nVidia gets those problems with PCIe4 straightened out in an upcoming driver release--but even so, you won't lose any performance by temporarily setting the mode for the card to PCIe3, should you deem it necessary. Doing that does not affect any other PCIe4 products--like drives--that you may install. They will continue to autoconfigure and run at PCIe4 mode. BTW, I noticed in my first post that I didn't specify that imo you should have a PSU that generates ~72 amps or more on its 12v rail(s). Also, don't connect the 3080 to a split power connector--use a dedicated connector from your PSU to plug into nVidia's funky custom power connectors...;) I have twin 8-pins on the 5700XT, and each has a separate cable connection to my modular PSU--some people have problems by using a single PSU cable connector that splits off, I've read.
Just the fact that everything is running fine with your system until you fire up a game indicates a PSU problem--usually. Doesn't necessarily mean your PSU is insufficient or bad--as it could just be a matter of your internal cabling from the PSU. Good luck and hope you get it sorted...! I just thought you should get a perspective from someone who is pleased with his x570 Master...;)
