Problems with RM850x

Hi folks.

Wanted to play Cyberpunk recently and during character creation my PC rebooted. I checked all the temps during stress tests(prime95, furmark + combined of two) and looks like that they are in acceptable range(CPU 94 max, GPU 72 max, SouthBridge 72 max, MoBo around 40). Running separate tests is fine: prime95 can run for 30 mins on small FFT and everytings works great, separate furmark is fine too. But if I try to run both of them simultaniously my PC reboots in 30secs-1min. I bougth 2 additional intake fans and things got slightly better in terms of time but still reboots. The fun part is that if I point a home cooler to the opened case tests appear to run fine for decent amount of time with no reboots.

So my question is could it be PSU overheating?

cyberpunk doesn't stress your computer even remotely close to what prime95 and furmark do.

 

94°C on a Zen2 CPU is a bit crazy, but again.. it's prime95 so no idea how hot it gets in realistic use.

Do you overclock GPU and/or CPU?

If you do, try at stock settings instead and see if it runs.

No.

 

It's saying that SOMETHING is overheating, but not the PSU.

 

If the PSU's over-temperature protection kicks in, it latches off. It doesn't just reboot. It latches off so it can give itself a chance to cool down.
