PC REBOOTING WHEN BOOTING UP A GAME

[herooftime21]

Hi so having issues with PC restarting when booting games after I did a fresh install of windows because I was selling the PC to a buddy. Updated BIOS all drivers and chipset tested ram. Only thing notice is the 3.3v drops to 2.96v and never actually gets to 3.3v highest it gets is 3.0v, also might be a stupid question but after my buddy picked it up he realized he forgot the power cord so he is using his from his really old omen PC that had a 450watt power supply.

Asus prime x650 pro wifi
Ryzen 5 7600x
Asus tuf 3070 OC
32gb ddr5
850watt corsair PSU
1tb firecuda NVME SSD

That rail is bad, 3.3 minimum is 3.135

Also is that 4.68V supposed to be a 5V Rail? If it is suppised to be a 5V rail then it is underperforming as well.

Get the correct cord for the power supply first and try again the 450 i doubt has the right gauge to support 850+

I noticed it'll sit at 3.05 and fluctuate but once a games is booted it goes to 2.96 and reboots

It's bad, try swapping to the cord designed for the 850 power supply, if it doesnt fix, replace the power supply.

The cord shouldn't make any difference, even the 12V rail is low.

It can due to gauge of wire, the 12v is still within atx spec of 5%
