I'm having a peculiar issue with my desktop where it will randomly shut down, and I can't figure out why. My PSU is an EVGA Supernova G2 750W, which I believe is quite a good model. I don't remember when I bought it though, could be anywhere from 3-5 years old. Rest of rig in sig, should be 5 years old this August.
What's puzzling is that it doesn't seem to matter whether the computer is under load or not. A few days ago I was running some simulations where my 4790k was running 100% utilization on all threads for 10+ hours without issues - the next day the PC shuts off while I'm not even using it. Temperatures are definitely not the issue either, I've made sure of that.
Winows does not produce a BSOD or any kind of error message, the PC simply shuts down and I have to push to power button to boot it back up. I think the issue started a few weeks ago, possibly after I formatted and re-installed Windows 10.
I've never experienced a failing PSU before so I'm not really sure what kind of signs to look out for. How do I troubleshoot? I do not have spare parts lying around to replace things one at a time.
