Question Faulty PSU?

[ZeyadBB]

The PSU is only 5 months old, my PC for the last month or so was randomly shutting down & restarting immediately with the kernel power 41 (63) event in Event Viewer, it was either at idle or during use, searches turned up that the most likely culprit is the PSU, but I decided to do tests first using memtest & OCCT, as well as resetting any OC I did & resetting BIOS to default.

Then, yesterday the PC shut down randomly again, but this time the PC didn't turn back on with no power going through, as in keyboard & mouse not receiving power and PC not responding to the power button, until I plugged the power cord to another opening on the power adapter, as soon as I did that I started hearing popping noises coming from the PC and I unplugged it immediately out of fear.

Is that definitely the PSU? Did I do damage to the rest of my PC?

PSU is EVGA 500 BR.

Specs:

CPU: i3 9100f
RAM: 16GB
GPU: RX 570 4GB
2 fans
1 SSD, 1 HDD

Thanks.

this is a very low quality unit.
it wouldn't surprise me at all that it has just failed while pushing this system.

the possibility that it also could've damaged connected components is always there.
but, you'd have to connect them to known working unit to verify for sure.

Your psu has a 3 year warranty which is not indicative of a high quality unit.
Better power supplies will carry 7/10/12 year warranties.


The only way to test for a bad psu is to replace it with a known good psu of sufficient capability.
If the psu was faulty, I doubt it caused any damage.
Borrow a replacement to test with if you can.

If possible, I would return it. Otherwise initiate a RMA for a replacement.

I understand it's a lower quality unit, there's barely any decent PC components available where I live and if there are they would be priced horribly compared to their international pricing.

I checked it on the PSU tier list before buying it to have been ranked at tier C, albeit being in the 'speculative' section of the tier, that means it has low ripple on the single 12V rail, sufficient efficiency & decent protection, that would have been enough for my low- end system I thought, I only use it for studying & some gaming, no real OC applied.

I just wanted to make sure that that meant it was definitely the PSU that went bad before initiating the RMA, I don't think I can return it where I'm from.

There is no way to be completely sure, except to replace it with a know good one - borrowed or purchased. Even new things fail.

EVGA BR units are lower end but still by far not unsafe units, this is not at all expected behavior. Should be able to reliably power a system of this caliber without problems.

until I plugged the power cord to another opening on the power adapter

What exactly do you mean by this. What was the PC plugged into?

Don't plug it in for the time being. No way to know what's damaged unless you replace the power supply. Check EVGA for warranty, they're support is very helpful typically.

The power adapter/outlet which is plugged into the wall that allows me to connect monitor, PC & charger together, etc, is what I meant. The adapter/wall itself is fine, monitor & charger are working fine.

Yes, I haven't plugged it in since, I managed to immediately unplug it as soon as I heard popping noises to hopefully avoid any damages.

I thought so too about the PSU, it says it's tier C ('speculative') on the tierlist, it came from EVGA which I know is good when it comes to warranty and it should've been fine to run my low-end PC, far from unsafe.

I managed to contact the local supplier & I'll be initiating an RMA soon.
