Hey folks, just building my third computer over a few years, bought the bits from ocuk about a month ago and everything going as normal except...

Plug it in and there's a spark in the PSU, the fuse trips in the house and there's an oh **** moment. Wondering how to proceed.

edit - tried the motherboard with another psu and can't get any power, that psu definitely works as it's currently powering my previous setup. Contacted ocuk to see what next steps are. Bum.

You didn't re-use the PSU cables (from a different model), right?

I don't think I'd try it again, unless you have some spare parts you're not bothered about.

Nope all new parts, only thing I re-used was the phanteks case. Removing the motherboard and plugging the old psu in to see if i can get power.

Hopefully it was just the PSU that blew.

Did/does the new PSU have a rattle?

Make of blown PSU? If its a good make then the rest of the hardware could be OK. If its not, then oh dear.

Nothing, brand new, first time powered up. Seems to have buggered the motherboard, or the motherboard buggered the PSU.

I know it is a bit late now, but when you get the new parts you should test with a bare minimum config, placing the parts on the motherboard box (not on antistatic bag!), motherboard, CPU, RAM only, use on-CPU graphics, and connect only the 24-pin and one 8-pin EPS connectors. Once you know it all works, then add the graphics card, and relevant power supply cables, and finally the disk drive (m.2/SATA etc.) install the OS, and make sure everything behaves as expected then put it all in your case.

Sounds like a plan for next time!

It's pretty likely your PSU is dead if it sparked and blew a fuse!
What motherboard is it? Did any lights come on with the working PSU?

Motherboard is a msi b760, and not a single thing came on, simply dead. Switched back to my previous motherboard and no problems. Really worried its taken components with it now.

Edit - just tested the gpu and it works so that's a positive.

Well at least the GPU is okay. Hopefully OCUK will be able to help with the mobo and PSU then
