Question Can an inadequate PSU make the GPU overheat ?

[eziowar]

Hi, my cpu i5-4670k, gpu - Asrock rx 7800xt challenger oc, mobo- gigabyte z87x-ud3h, bios version F10b, psu corsair cs650m, corsair ram 4x4gb @1600 mhz dual channel, Crucia MX 500 500gb ssd, ,windows10, cpu cooler-Hyper 212X.

Today I bought Asrock rx 7800xt challenger oc and after like 1 hour of gaming i got green screen crash and my cabinet near gpu and the gpu itself was super hot. so i guess that crash happened cause of gpu overheating mayb? if so, then can the cause of gpu overheating be because I'm using only 650 watt psu instead a 750 watt psu?

for past 6 years, i've been using gtx 1050 ti on that same system and never had a green screen freeze .

superhot as in what exactly?

i touched and those were very hot (cabinet's body which near to the gpu and the top metal plate of the gpu)

They should be hot. The proper way to diagnosis this is the actual temperature, not touching it with your fingers.

ya i was monitoring temps, but i wasn't expecting crash, so was bit ignorant to the overlay which was showing gpu temp. So dont know how much temp my gpu reached during crash, but during gaming i saw around 70-80c gpu temp and also gpu was using upto 270 watt.

That's not a concerning temperature.

Are all these crashes green screens? Any that just turn off the PC? I ask because that was an OKish PSU from a decade ago and really should have been reused on a new, higher-end GPU.

i had crash only once(my total PC runtine using new card is about 4 hours) and it was green screen freeze and it happened when i played "black desert online" on ultra settings( after playing like 40m), but pc did not turn off automatically

btw, i just came to know that temp i said earlier was normal gpu temp, but gpu hotspot temp is most times 20 more than that, so hotspot temp was around 90-100. is that temp concerning?

Hotspots in modern GPUs tend to be really hot.

Honestly, if you've only had one crash, I wouldn't quite worry yet.

Tyvm. after that crash i have manually configured gpu fan speed and now during gaming gpu hotspot staying around 80-85c and no crash happened again. Can u plz tell me how much hotspot temp is concerning?

I can't imagine that it could. Excess heat comes from an abundance of electricity not a dearth of it and a card getting less power than it needs won't be able to run hot. If the card's running hot, it's not because of a weak PSU, it's because there's something wrong with the card's cooling system. Usually, it's something as simple as the fins being clogged with dust.

Until proven otherwise this is the cause of your crash.
It's not a good idea to do this (run the system with a known inadequate power supply).

Also a really big GPU for a relatively old CPU. Another problem you may be having is maxing out your CPU cycles trying push frames, plus the extra heat coming off the GPU (Because a 1050Ti uses a lot less power than a 7800XT) might be having an effect on the motherboard and general stability.

If you can increase the airflow in the chassis at all, or replace the chassis with a more airflow oriented one that would be a good idea.

But I agree, if that PSU is as old as the CPU, probably due for a replacement anyway. And running a high end GPU with it isn't the best idea.

Though really you should be looking into a new CPU/Motherboard/RAM/PSU/NVMe SSD at this point. Even an i3-12100 would be a massive improvement, or something like a Ryzen 5600 or i5-12400.

Ty, i increased the airflow, and my gpu temp improved by allmost 15c
