[SOLVED] PSU Question (might be a dumb question)

[ekalhaikal45]

Specs:
CPU : i7-10700
GPU : RTX 2060 MSI Ventus GP OC
RAM : DDR4 CORSAIR Vengeance 2x8GB 3600mhz
MOBO: ASRock B460M Steel Legend
PSU : FSP Group Everest 88PLUS 700W (yeah, i know.)

I've been getting crashes on certain resource intensive games, in my case, it's mostly Apex Legends.

I'm confused because it ran fine for like 10-20 minutes before completely freezing the computer. Couldn't restart at all, only way was to force shutdown it by holding the power button.

In this scenario my GPU used on average 70-80 Watts, while my CPU used on average 30-35 Watts.

So in what might be a futile attempt, I undervolted it and got around 40-50 Watts on my GPU, while my CPU stayed relatively the same, at around 30-40 watts.

It crashed after 10-20 minutes, exact same result as when I didn't undervolt it. (I didn't OC anything either, just plopped the CPU and GPU, installed the proper drivers, and just that)

My question is, if the PSU is the culprit here (Which I highly suspect here, but I'm just making sure at this point), what's the main cause? Like, what can make a PSU crash my PC? Is it a sudden voltage drop or something? I'm curious

Sounds more like a motherboard problem than a PSU problem, but either way you need to replace that crap PSU.

What about a poor power supply can cause a computer to crash? Everything.

Low voltage, high voltage, low power delivery, high power delivery, overheating, high ripple currents.

I agree though, probably want to start monitoring motherboard temperatures. And the usual, check for CPU and GPU overheating.

Replace that oldtimer PSU first!

Yes, I am planning on replacing my PSU.
How would I monitor my motherboard temperatures, though? And what temperatures are considered dangerous for it? (asking for mobo because cpu and gpu temps are fine when i was tracking it with afterburner) (cpu and gpu temps were around 45-60 and 40-60 respectively)

That's the first thing you have to do before further troubleshooting and asking questions.

I'm putting this here, just in case:
Turns out my CPU was overheating, one or two of its cores was reaching around 70, might be because of bad paste. downvolted it to around 10 watts of average usage, still runs apex fine on 60FPS all settings maxxed out. No more crashes.

Still gonna replace that PSU though, this thread really hammered in me how old the thing actually is. Might actually be the main issue since it was fixed because I downvolted it.

(p.s take everything here with a grain of salt, i wouldnt even consider myself an amateur)
