[HELP] PC suddenly shuts off (lemmy.crafty-codes.ch)

As stated in the title my PC suddenly completely shuts down as if i would lose power. I am pretty sure that it is the Power supply but i wanted to ask if it even is possible for a CPU or GPU to just let the whole computer lose electricity before i buy a new PSU

It's important to know what's going on when the computer cuts power. I had this start happening to me when I was playing VR games. I had been using the same hardware to do so for a year beforehand, but it turns out I was just riding the limit of what the PSU could supply. When I actually took a look at how many watts the UPS was reporting it was happily under the PSU's rating, however Nvidia GPUs are known to power spike at times and draw way more power than they're supposed to. That's what was causing my issues. An upgraded PSU indeed fixed everything.
