In January I built a computer and used an EVGA SuperNOVA 750 GT, 80 Plus Gold 750W and my computer has started to restart occasionally, but only when I've been playing some slightly more demanding games for a little while, and I have checked every other component and they are all working properly, with the exception of my PSU. The fan spins for 1 sec on boot but never more. Not even under heavy load, and I was wondering if there was any way to fully confirm if it is defective, or if something came loose in the PSU itself.
And I could finally reproduce this issue not just during gaming.
So I started to stress test my GPU, it works fine. Never switch off.
But as soon as I starts the stress test also on my CPU (besides GPU stress test is running), the system is immeadiately shutting down.
And I cant switching it on again. I had to turn off the power on PSU, wait approx. 10 sec and then switching it on again and finally the power button works and it boots up.
Please help!
System config:
MOBO: Gigabyte B650 GAMING X AX
CPU: AMD Ryzen 5 7600X
RAM: Kingston FURY Renegade 32GB (2x16GB) DDR5 6400MHz KF564C32RSK2-32
GPU: Gainward GeForce RTX 3070 Ti Phoenix
SSD: Kingston KC3000 1TB M 2 NVMe PCIe (SKC3000S/1024G)
PSU: EVGA SuperNOVA 750 GT, 80 Plus Gold 750W
