Question Computer shuts off abruptly. PSU problem?

[Volfenshteinya]

Hello, I think I have a PSU problem but just wanted to ask here to see if anyone else has any ideas. Recently my computer just shuts off and turns back on instantly. Like it dosent even windows shut down its almost as if someone pulled the power cord to it. I swapped walls plugs, and even installed a battery backup but it keeps happening. Also, sometimes the monitor randomly turns off and on. I have a corsair rm850 gold, so power should not be an issue. Im considering replacing the PSU since it is about 6 years old, unless someone has any other ideas. And there seems to be no particular event that causes it, I can be playing games and have it happen or just browsing the web.

I dont think its your PSU, your PSU is not powering your monitor is it?

psu do power the gpu

to the OP
just random shutoff? that tough to test.
Get a psu for testing.

does it shut off when its idle?
my cousin has a shutdown issue and it only happens when at high usage.
PSU and keep up with graphics card usage.
