At this point I'm looking for any outside opinions on what might be happening.https://pcpartpicker.com/list/VvTk2R
To the best of my knowledge off the top of my head, this is my build. A few wired controllers and external hard drives aside. So basically since ME Andromeda hit, I've had an issue where when I'm playing certain games... the PC just shuts off and I can't turn it on for another 10-15 minutes or so after unplugging it. ME Andromeda was the first. Anywhere from a couple hours to a few hours, to maybe half an hour, I'm playing fine, no signs of anything going on, and my PC literally goes dark. Everything dies instantly, display goes black, fans whir down and my PC's a heavy brick. 10-15 minutes after unplugging it, you can plug it back in and everything just works fine.
When this was first happening (same build) I upgraded from a 500w Bronze PSU to a 600w Bronze PSU. Immediately, seemed to do the job. I was playing ME Andromeda without any problems, right up until I said "this game's dumb" and quit. Fast forward to the announcement of Shadow of War, and I'm like, I need to beat the first LotR game! So I fire it up, playing four, five hours, PC goes dark. Get it back up and running, play 2 hours, PC goes dark.
Frustrated, I start turning details down and limiting framerate, and ...it KINDA seems to be helping stability? Anyways, I finally get through the game, think my problems are all over.
Yesterday, bought the new game. Played it for 30 minutes, PC goes dark.
During normal use the PC can go as long as I need it to, emulation's fine, MOST games seem to play fine. Is it the power supply still? Looking at what I can see from the wattage draw, 600 SEEMS like overkill. What the hell's happening? Temps for the CPU seem to be staying relatively chilly as far as I can monitor them, around 45-50c peak, 32-36ish idle. GPU gets a bit warmer, it's hitting 77-78c during stressful times, but all of this seems like it's in spec.
