This was and still kind of is my gut feeling. My PC sits on top of my desk and is situated at the corner of my office space. I also live in what is easily one of the hottest climates in the United States so my room temperature is probably much higher than what others might be used to for purposes of not spending an insane amount of money on electricity each month having my AC run continually (78-80 F) I just moved my PC forward a little bit so that there is more space in the back for airflow once my system is under load while in game. I played 30 minutes of ALTF4 last night and had no crashes which was rare, so I'm going to continue to do some more testing under my slightly new setup to see if I encounter any crashes in that game or Risk of Rain 2 where I encountered a crash a few nights ago.To me this sounds like PSU overheating problem. How to check it? Move your PSU out of case and put a fan blowing on it (preferably in such way so the extra air goes to air intake on PSU). If it stops crashing or considerably increases the time it can work before it crashes this would be strong sign of overheating.
Do PSUs typically have temperature sensors that can pick up this data? From researching my own PSU I know mine definitely does not, and this is not information I'm getting in CAM.
