Hello,

My motherboard is using 13.82V in the 12V thing. Is this a problem?

Corsair HX750 Prof. Series PSU
and MSI 870A-G54 mobo.

it should not go above 12.6 or below 11.4

do you have a multimeter to test it with, that seems wrong lol

Most likely CPUID is wrong if you do not have multimeter check in BIOS.

Yeah, well reason I ask is.

My computer randomly restarts while playing games.

And the theory is that something is drawing to much power, or something on my motherboard is screwed up, and my PSU is like, No more. And restarts to prevent damage.

So that's why I think this is a problem. Otherwise I have no idea why my computer randomly restarts.

13.82Volts is WAYYYYYY too high. I've heard of some shitty knockoff power supplies going as high as 14V so I don't doubt their existence.

Honestly if it was actually running that high your motherboard would just refuse to turn on.

Well what should I do than? Because this random restart stuff is quite annoying.

usually if your components are drawing power, the voltage will lower... i would send it back and get a replacement to see if that helps

I just looked at that image you posted. It's definitely misreported. If it were reported correctly the max,min and current values would all be different, not the same. Voltage fluctuates slightly when in steady state and goes up and down to accommodate transient loads.

It could still be a PSU issue, take a look in your system setup's hardware monitor

what dont you understand? my 12V rail goes from 12.1 to 11.88V, they normally fluctuate in voltages, but if you look yours hasent shown any fluxuation at all which is most likely a misread...

if you go into the BIOS hardware monitor, it might be a little more accurate

Ah. I didn't get what he meant by your system setup's hardware monitor. Now I get it. Will go check.

EDIT: Checked BIOS. It said 12.056V. That's good.

And I am now assuming it is randomly restarting because I don't have it plugged into a surge protector.

The lack of a surge protector won't have anything to do with it unless you regularly experience massive power fluctuations. In that case you're better off getting a good UPS
