As title suggests.
Coming home the other day I find my PC started to restart out of nowhere, with no warning before or errors afterwards. I haven't changed anything and haven't had this problem before.

Any suggestions on what to do?

Yeah, about that... I had 110w cpu, max 200w gpu, other than that only minor things that don't have much power draw and my at thst time 800w PSU was the minimum.

I upgraded gpu, sometimes 300w spikes and that was it. Now have 1000w PSU. And since it happened so randomly clearly I'd think it's your PSU. 700w would be fine if it was guaranteed, but it isn't.

    Got it. Its weird that it never happened before but its good to know what it could be. Memtest is running while I'm away but if that shows nothing I'm afraid its the PSU

    I'm not sure how it is with Nvidia, but with AMD you can have the metric overlay running or even logging, so you could see if it happens on power drain.

    For me it mostly happened only in one game (everspace 2) and only certain scenes and then not even always.
