Question PC randomly restarts. No bsod message just randomly restarts

[museprime]

i have a pc I build myself. Not my first rodeo. Everything seems fine. Everything boots just fine. It’s zippy and quick. I think I’ve tried everything to figure this out. Any help would be appreciated.


Here are the stats

Ryzen 5700X3D
CPU cooler Thermalright AXP90-X53 full copper low profile cooler
Vengeance DDR4 32GB 3600
Asus Rog Strix B550 I gaming motherboard
Nvidia 4070 Super FE

You forgot to mention the make and model of your PSU. How old is the unit? What sort of temps do you see on both the CPU and GPU right before the system shuts down?

S400 case
You mean the Coolermaster Silencio case?

What have you tried prior to creating this thread? It's so we're not repeating steps that were unfruitful.

PSU is a Corsair sfx 750. My temps on my GPU is like 30 c and my cpu is like maybe low or mid 40. And probably 50ish-70ish depends when gaming depends on the game. I don’t see as often when I’m gaming.

The case is a s400 shiny snake

I’ve made sure everything is updated. Bios etc I’ve checked my hardware Power management option.
