Hi,

I had a pretty traumatising event the other night, I put together my brand new computer everything (seemed) to go perfectly well and then I turned on the computer. It worked and I was looking around the CLICK Bios that comes on my mobo and then suddenly pop my entire circuit breaker in my house goes off. Then I press the computer back on and flash bang the psu blows up. I smelt burning coming from the psu.

I had no idea what the reason for this was, I triple checked every connection and every wire and they are all correct, (everything is in the right slot and all that) then I looked on this forum and saw that extra standings behind the mobo can cause a shoe circuit. I left a few extra standoffs behind my mobo so I assume that is what cause the short.

I need advice on whether that was definitely the problem or if it could be something else? Also what are the chances my mobo is fried or any of my other components?

Thank you in advance for any help and sorry for long post.

I read else where that the quality of the psu affects your chances of other parts breaking, is that only if it is a defect in the psu?

I did only smell burning from the psu and a flash from the psu, I checked and didn't see and blown capacitors on the mobo if that means anything?

I'm kind of sitting here with my fingers crossed.

EDIT: Also is there a way of testing the mobo without a new psu cause I won't get a new one for about a week?

you will have to check it with another PSU. Also double check your wall socket and cable. Blowing a PSU like that off the bat is strange unless it was one very faulty PSU

I checked the sockets afterwards and they were all fine for any other electronics and I forgot to mention I had it plugged into a surge protector which was plugged into the wall if that makes a difference?

The surge protector does work definitely. I checked that.

Yeah I thought it was odd also.

Could just be a very faulty PSU, My friend got a Visiontek 800W for his new build and it was alive long enough to get the OS and some games installed. After playing Planetside for 30 mins his PC shut off and we smelled burning plastic and looked and the inside of his PSU was melted and his case full of smoke. So I am guessing it is not uncommon for outrageously faulty PSU's to get out like that. You are lucky you psu was not that bad.
