Hey All,
I have a 6 year old self-built PC that started exhibiting signs of a possible PSU problem but I wanted to see if I could confirm that before I buy a replacement PSU.
About 4 months ago I discovered that if I attempt to play basically any game my system will suddenly power almost completely off after a few minutes of gameplay. This includes games that are not pushing the system to it's limits (world of warcraft, etc) and the graphics settings don't seem to change the behavior.
Essentially what happens is the screen cuts to black, the fans, etc all stop BUT the RBG built into my memory modules continue to be illuminated. I can't power the system back on unless I turn the switch on the PSU off and on again or disconnect power entirely and plug it back in. After that I can power the system back on as usual.
The system exhibits zero issues when not playing games at all. Google says this is possibly a sign of a PSU failure/overload but given it only happens when I attempt to play games I haven't ruled out that the faulty component may be the GPU.
The system has a Corsair HXi 1000 watt PSU and a Radeon RX6900 XT GPU. The one thing I want to note is that the GPU is semi new to me as a friend gave it to me since I was still running a nvidia 1080ti until last December. I installed the new GPU back then and played some games and everything seemed fine. I don't game on PC as often as I once did so I went about 4 months without playing anything and then when I booted up WoW in April this behavior started.
Is there anyway I can definitively diagnose what the problem is or is this a situation where I should basically try replacing things (putting my old GPU back in, trying a new PSU, etc) to figure out the issue? Thanks!
