PSU turns on then off

so, my computer had the symptom of spining the fans for a second then not starting, and i managed to isolate the problem to the PSU.
i have tested the PSU and efectively it turns on for a brief second then turns of, i did this by using the paperclip bridge trick, i looked at all the cables from the PSU to check out everiting was ok and it didnt had any shortcircuit, then i took it apart (doesnt have any guarantee anymore anyway) and everiting seems to be fine on the inside, y have looked even into the PCB and i have cleaned everyting with alcohol and still not working.

any ideas on what could it be? is there any way i can fix it?

Your pc is probably in over voltage protection mode. you need to unplug the psu and remove battery from mobo for at least 1 hour.

Replace your PSU.

This^

 

I was able to reproduce this issue on my system when I was diagnosing my brother's computer. So he'll be getting a Corsair RM850i as a replacement simply because we know Corsair to be reliable, based on our experience. But I do have confidence that Seasonic is also reliable, but I won't be taking chances anytime soon.

i forgot to mention, the PSU is a 600W Seasonic SS-600ET, yes im planning on replacing it but i just want to know if its there any chance of fixing it or bringing it back so i can use it as a "backup" or test PSU

the PSU is alredy outside of the system, im pretty shure that the motherboard isnt the problem because i tested it with an old motherboard and i isolated the issue to the PSU.

You can fix it, but only with the right tools, probably some soldering, and a whole lot of caution because touching things in the PSU can kill you. 

 

It's really not worth your time. That particular Seasonic is nothing special.

Can you fix it? Sure... Should you? Not really.

PSU's can be really dangerous to work on if you don't know what you're doing. This seems like evidence of a short rather than straight up death, so it looks relatively fixable, bit I would suggest you get a replacement.

Intel CPU, Motherboard and Overclocking settings.

PSU can't do that.

Well, in that case, replacing the PSU makes sense.

That's an old unit...

since 2018 i replaced the PSU with an EVGA 600w 80plus, but recently i got the same issue again, since 2018 i got some knowledge on electric circuits and some prety cool tools to work on PSUs (electric tester, soldering iron, ect) but i still dont have enough knowledge to work on it.
last time i took it to an electrical technician who used to fix anoter PSU that i needed fo a dell workstation.
 

i got to the conclusion that its better to take it to an electrical technician, usually they charge arround $25 to get it fixed, and thats cheaper than most brand new PSUs.

im gonna get this one fixed since rigth now in the area i live they are hard to get rigth now.

Exact same problem as before?

 

What was the "EVGA 600W 80 PLUS" PSU you bought?

 

Are you *sure* it's not the motherboard?
