I just had a powersupply pop and smoke all over the place......i just took the machine in from a local jewlery store? Its a no name OEM ps.

1)What are the chances it fried other stuff
2)Why would it pop and start smoking like that?...it wasn't to dusty in the case.

Thanks

It depends on what part of the power supply fails.

When the line section of the power supply has a failure - eg, input rectifier, PFC, main switching transistors, primary side drive, etc... usually the supply fails with a spectacular BANG but doesn't take any computer components with it.

If the output section of your power supply fails (secondary side rectifiers, magamp, output capacitors, control circuitry, etc)... normally you end up with a quiet but stinky failure, and dead computer hardware.

The Powmax supplies i've encountered invariably blow their primary side... the undersized transformer saturates, main transistor current goes too high, main transistors blow, and the supply drops dead without harming anything. This is the only good thing I can say about that company. :D

Deer supplies, with secondary side rectifiers stupidly-fucking-formed by soldering axial diodes to a metal heatsink... those almost always kill computers. I've seen holes blown in motherboard chipsets due to deer supplies...

So the bang while seming bad may have resulted in not much or any loss.
 
Well thats a relief...it did smell nasty though...ill throw another ps in there and pray :rolleyes:
 
haha I didn't....I just got the machine in the shop...sheesh i know better than that. ;)

Don't take my words as the bible. It's entirely possible for a supply to go BANG and take your computer entirely with it.

Just replace the PSU and cross your fingers...

Why leave it to chance? Open the supply and look at it for signs of damage. When you see what component is damanged, you know what happened!

Without sounding rude I am not but it pretty much meshes with what I have experienced in the past. On very few occasions have I had "loud" PSU failures wipe out things......sadly enough it was a Foxconn(Deer) most recently.
 
haha it was my ps exploding cherry that was popped. I was flippin out for 5 min thinking everything was fried...looks like everything is working now that i have the new one in....then again everything only seems to work...give it back to the stupid sales ladies at the jewlery store and i give it another week before its back in here :eek:
 
The pop was a big ol' cap meeting its maker. Those are fun, I've seen a bunch of them so it doesn't phase me, but man, i've seen guys dive under the desk a couple times. :D
