PSU pop, HELP!

Crap.

So I built KingPenguin (my new rig) and it all worked just fine. Installed Windows, drivers, etc. Was just doing some stress testing when I noticed one of the cores was about 15 degrees cooler than the others, and the others were running a bit high. So I decided to remount the cooler to see if that helped it any. After cleaning, remounting, etc. I flicked the switch of the PSU and *POP!* Sparks coming from the PSU, rig wouldn't turn on, and the main switch in the fuse/powerbox (don't know what to call it, the house's main power switch) was flicked.

I took out the PSU and examined it, and upon looking through the back mesh I noticed there is white stuff coming out of some components in it. So the PSU is definitely fried.

How could this happen? It was working just fine, all I did was turn the rig off, flick the power switch on the psu, clean the CPU, reseat the cooler, and upon flicking the switch again it all popped!

Any ideas, help, anything at all is welcome. I hope none of the other components took a hit.. how big's the chance of anything else being fried? What should I do now? I can use my lil' brothers HX750w from the rig I built for him to test the other components but I don't want to kill his PSU too..
 
test each component separately, looking at your spec i doubt that a 600w could handle such load, I mean 2133 4 sticks + 3770 + 7970 and a bunch of drives, i wouldnt even come close to it without something like hx850

600W is barely a minimum for something like 7070 and if you throw all of that extra power needs together, even a good branded psu cant handle it, it should have some protection from that tbh, i would test the psu first if its dead or not, bridge the pins on 24pin and try testing one piece at a time, 3, 5, and 12v rails, to see which one is dead and potentially fix it, for future htpc etc.

No that's not it mate, PC with all components fully stressed and overclocked would pull a max of 550w. And in any case, the rig wasn't even turned on yet! I just flicked the switch on the back of the PSU and it popped.. O.o
 
I'd say the PSU died due to a power surge seeing as the switch powerbox in your house was flicked, or it could simply just have been a dodgy PSU but the rest of your components are most likely fine. Put a new PSU in and you should be good to go, but make sure the plug socket used by your rig or the powerbox itself is ok (just to be on the safe side.)

600W is fine for that build mate, so the amount of power did not cause the pop.
 
Cheers fellas! I guess I'm forced to buy a new PSU though.. won this one and I just can't wait for CoolerMaster to replace it, will probably take weeks. :'( Will be going with my original plan, AX850!

Don't think it was a power surge as the pop happened right when I flicked the switch on the back of the PSU.. very strange because I've hotwired this PSU a couple of times to test some fans and it was fine. The rig even ran off it for about an hour, didn't pop when I fully stressed the cpu.. what could possible have caused this? Still not very confident about hooking up a new PSU, cause if that pops I'm definitely screwed.

What'd you say is the best way to test the wall socket?
 
ahhhh the old cooler master silent pro 600 watt psu. I had one of those once and its the reason i will never buy another cooler master psu. I hate to tell ya this mate but that psu verified by independant testing maxes at 430watts. The silent pro line was complete garbage. There current ones are better and run at rated specs but fool me once shame on you fool me twice shame on me. You were lucky it lasted as long as it did. I still have it well its inmy ex's rig lol but it aint doing nothing but an am2 proc hdd dvd and slot powered 4370 gpu with no overclock and its running fine.

I came about the info when I was struggling with it trying to oc a rig so i googled it and found alot of bad info on it. Hopefully since it blew the breaker the pop when back and not forward and the rest of your stuff survived. Gotta say it may be shit for watts but looks like its power protection worked at least.
 
Yeah but it's not the regular Silent Pro one it's the fairly new Silent Pro Gold range. From what I've heard these should be just about the only solid PSUs from CoolerMaster.. =/

Cheers elder_scrol, I'll do that straight away.
 
yeah sorry i missed that gold part yeah its not the same as what i had. But imho if it popped i wouldnt trust it bin it and get another one your plan for an AX850 sounds spot on.
 
Yeah I'll do that. But could it be that something in the PC shorted it out somehow? I'm clueless as to how this could've happened..

Edit: checked the wall socket but there doesn't appear to be anything wrong with it. Doesn't even have wires by the way, guess that's cause it's a fairly new house. Doesn't smell funny either.
 
just give the whole rig a good once over ya might of gotten some tim where it shouldnt be or maybe some of the cleaner got somewhere, but my guess is the psu just gave up the ghost since it popped and you dont see anything else. if it was the wall socket you'd see it at the socket. if it was the board youd see something there as well. probably something with the switch on the psu was faulty.
 
I TOLD YOU DUDE DAMN MAN, I TOLD YOU!! I KNEW THIS WOULD HAPPEN

get a AX750 and enjoy your pc

I use Arctic MX-3 and that's non-conductive so that shouldn't be it, and the cleaner only touched the cpu so that should be fine.

Now testing the rig using my little brother's HX750w and seeing as I'm writing this post my rig seems to have survived!
 
A few years ago, i bought silent pro 600w as well for my first build but returned it the same day and got the M850. In my experience cooler master have been reliable. Your PSU could have been part of a bad batch of them, other than that, they are good PSU's imo.

I recently bought a AX850 and i couldn't be more happier with my choice. Its definitively the one to go for your build

Yeah. Friend of mine said it could be down to bad wiring though, could it?

Look at those idle temps.. Core0 is 14C? My room is hotter than that.. how's that possible?

You must have bought a cooler that breaks the laws of physics

either way, your problem was that you bought a CM PSU.

ALSO to other posters, my rig is an 2500k, gtx680, GENE-z Gen 3 board, 8gb 1600mhz, and my max power draw at stock clocks is 430w.
 
Yeah, very strange indeed! Well, perhaps it was that cool in my room. Windows was open and it was at night. I was stressing out so I wasn't cold at all

But then it must've been within 1 degree of the ambient temp..

And I must stress that I didn't buy the PSU, I won it. I would never buy a CoolerMaster PSU.

Should receive my Corsair AX850 tomorrow. I hope that fixes it!
