Random power off

[Sam.MP4]

Hello I built my first computer while on vacation and everything worked fine. I shipped it back home with UPS I did some inspection  because the CPU cable came free so I double checked everything else and it seemed fine.  One day I wake up computer was off and moved. I thought, "Well that's weird." I looked in event viewer and apparently it safely turned off so I thought nothing of it. Today I came home and it was off... But in sleep. I pressed space bar everything booted fine. For some reason for my system sleep isn't really sleep. It fully powers off but still responds to a keyboard or mouse movement. I went into event viewer t see what happened and I got this critical error is it my PSU? It feels cold to the touch and the fan is running I turned ECO mode on and heard the fan slow down and turned it off to see if that made a difference and heard the fan start up. My PC idles around 30 C. While gaming it goes up to about 50-60 C. (PSU excluded). Should I take it into the repair shop for diagnostic?  It is also plugged into a surge protector if that makes a difference. Edit: I also updated my GPU driver to 436.02

Here is my question, is it something random like a random thing with the chord surge protector or the wall outlet it’s connect to or something like that or is it something wrong with my PSU?

Computers don't just move on their own. Maybe whoever moved your computer also turned it off? Or the power cable pulled loose while they were moving it. Who knows.

This doesn't sound like an issue related to the PSU. Nothing to worry about (except if you live alone then you might be questioning who is moving your computer while you sleep).
