PSU Went Bang... But...

post #1 of 8
Thread Starter 
It's still partially working!

So I turned my PC on earlier, and heard a loud pop, alongside a blue flash emanating from the PSU. I took it out and sniffed it - definitely the culprit! I tested it with a piece of wire (jump start, no mobo), without it plugged into any components, and it still started up, though.

Not wanting to risk it, I plugged in my old Dell PSU (hoarding FTW), and made do with that. However I realised I wouldn't be able to power my GTX 260 with only 1 PCI-E power cable. So I plugged in the "broken" PSU, and used that to power one of the PCI-E power slots, and the Disk Drive.

What do you lot think could have gone wrong, then? A blown capacitor? I'm suprised it's still working, especially seeing as the computer powered down when the initial pop happened.

I've sent off for an RMA, so hopefully I will get it sorted ASAP. I won't be playing any games that's for sure, but just wondered what you guys thought, regarding the safety of using that "broken" PSU.

My roomate had a silverstone psu that did the sameish thing. I used it for benchtesting a WC loop for leaks and testing fans. It will never go in a system, but after my checking I found that one of the rails was dead. I keep it around to test fans and stuff like that.

It is probably one of the caps on the primary side that decided to retire prematurely. It's hard to verify without opening the PSU (and voiding the warranty). If you peek in with a strong flashlight, you might see chunks of electrolytic material inside.

If it was a Primary side cap, the thing wouldn't turn on.

@OP, was this your HX520?

For a blue spark? That's usually an electrical ark.. so it could be a few different things.

Yeah you'll have to send it back to them, but I do believe Corsair does Cross-shipping.
So you send them a PSU, they send you a PSU and take your CC number. If there's a problem they'll charge you, but if it's legitimately dead or broken (like yours) then they don't.
