My desktop will restart without any noticeable reasons for each. Has restarted right after boot and 3 hours into running. Started happening multiple times a day.
I do not get a blue screen. I dont get a sound or alert. It simply shuts off and restarts within 3 seconds. I have looked through dozens of forums and similar experiences to try to find a solution. Without the ability to start swapping out pieces to see if its a hardware issue, I wanted to get another opinion encase im missing something.

Windows 10 home (Boot up and installed from flashdrive)

1) I have checked the temps several times. Nothing is overheating.
2) Was happening before I installed the GPU.
3) Ran a stress test on RAM using Prime95 (passed)

Have done some small things here and there. I would like any advice. Anything to avoid having to replace my hardware. At this point, I assume that it is probably my PSU failing for whatever reason. I have only had it 2 years and never come close to maxing it out.

While trying to play PUBG I noticed a pattern. I would start up the game, and before it was done loading to the menu, the desktop would restart, it did this twice before it actually let me play the game, and then restarted again the next time I went to load the game.

Evale, sounds like your maxing out your PSU whenever the GPU takes on a load. The PSU failing is probable, but without a PSU tester you can't be sure. Did you have the same exact problems before the GPU was changed?

Well I built this desktop with the gpu and psu installed at the same time. I’m using the psu from my previous case/system. Which was a much lower quality AMD setup. I still had these issues in the previous case, with a very low power gpu.
