If a psu starts shutting your computer down you know that thing is waiting to blow up, swap the psu as soon as you can

 

maybe the psu voltages go haywire for some reason, back when i was using generic oem psus for my p5q the 12v voltages got up to 14.2v and it does shutdown quite alot, not to mention the cpu vcore going nuts, i set vcore to 1.6, idles at 1.75c but under load it droops to the expected ~1.55v (llc off)

I see i already bought a replacement just wanted to know why was there sound in the psu that was not from the fan

Yeah so that thing is defective. Good news tho it came with a loooong warranty period so can still send it back for rma and get a nice new one back.

Is it actual shutdown or restart ? If it's shutdown then can you power the PC back right away with the button on the case or not ? What are other PC parts ? Are you using cable extensions ?

It's normal for older PSU.

Not really a shut down it blacks out and i have to cut the power off to the pc for 30 seconds before i can turn it back on again, i used to have extensions took them out but the problems persisted

Ah... yes... Worked fine with your previous build, didn't it?

 

That's a common issue with Seasonic made PSUs and Ampere cards.

Old Seasonic Focus had the same problem with AMD Vega, they're very power hungry cards and introduce some noise back through sense wire to the PSU which causes the unexpected shutdown due to the flaw in PSU design. New nVidia Amperes are very similar in all that. Old Seasonic SnowSilent (and the new one too for that matter) apparently had the same issue, and in addition to that it's just an old unit overall. You can try to contact Seasonic about that if it still has live warranty.

I see so its just a design flaw. sadly this was from cousin and he opened the unit up before destroying the sticker.

Okay.  Then there's one thing you can try.  Locate the +12V sense and remove it.  You'll know it's the +12V sense because on the 24-pin, it will be the +12V with the double wires.  The thinner of the two wires is your sense wire.  Just cut it or pop it out.

One of the pins on 24-pin motherboard connector would have two wires coming out, one of them would be thinner (higher AWG gauge), you follow that wire back to PSU side of the cable and pull that pin out. To do that you'll need to push two tabs on sides of the terminal from the connecting side, get some thin tools or pieces of metal or thinner paper clips, insert them between the terminal and plastic housing and pull the wire. All that obviously with the PSU disconnected from the mains but technically you're working only with the cable so it detaching altogether would be easier anyway.
