TL;DR at the bottom
A few days ago, while loading up a game, my PC decided to lose all video signals and the GPU fans started spinning at max speed. No big deal, it has happened before. A restart usually fixes it.
Except this time it didn't. There was still no signal.
I opened the case and it smelled like burnt plastic, badly. I thought it was the PSU (a Seasonic S12II-620w), so I obviously got worried. Eventually managed to get video signal back, but upon booting into Windows (10 if it matters), it would instantly shut down and kinda act like its struggling to start up (starts turning on and instantly dies again). All the while it worked fine in BIOS and Safe Mode (go figure..).The voltage in the BIOS seemed kinda off, low 11s/high 10s. The burnt smell never went away too, so I decided not to risk it and get a new power supply.
Cue 2 days later. New PSU arrives, a Seasonic Focus Plus Gold 650w. I get everything connected, turn the PC on aaaaaand nothing. The fans are spinning, the peripherals are on, but there's no video signal. There's also a clicking noise from the PSU. When I say i've tried everything, i really mean it. 3 different GPUs, cleaning the CPU, the CMOS jumper, a NEW CMOS battery just in case. It just wouldn't POST. While it was at least booting earlier (with the old PSU). Used a multimeter to measure the voltage and when connected to the motherboard, they would jump between 12 and 9, as if something was straininig it. So the verdict was either a dead motherboard (or a dead CPU, hopefully not both).
I've already ordered a new motherboard, that's not really the problem. What I can't decide on is if I should even keep the new PSU? I've jumped the old one and measured the voltage on most of the pins, it all seems perfectly good (there's this one blue cable that is 11.60w but afaik that's within reason). I opened it and there is no visible damage inside, i've also left it running for about half an hour and there's no smell whatsoever.
I'm not opposed to keeping the new PSU but there's no reason to throw away the old one if its not even to blame the motherboard simply decided its time for it to go.
TR;DR:
PC shut down, bought a new PSU cuz i thought the old one was at fault. PC went from booting (barely) into BIOS/Safe Mode to not POSTing at all. Turns out mobo is fried and old PSU might be perfectly fine. Should I keep it or change it for the newer one just in case?
