The other day I went to go turn on my comp and it wouldnt start. I got kinda mad and pushed the on button 5 times really fast (like an idiot). Two seconds later there was a loud crack and smoke started coming out of the power supply. The noise scared the muck outta me LOL. Im wondering what could have been damaged. There was no smoke coming from the rest of the computer. I have already ordered a new power supply which is on its way. Now im just scared somthing else is damaged like the whole motherbroad or the hard drive is fried...Now I know not to trust standard case power supplies. What are the chances somthing else is wrong?

Probably not to much. If your computer wasn't running at the time the thing blew up, there's afaik little danger that any power surges messed up any of your mainboards components. Just try the new power supply (it will certainly cause no new damage).
This sort of thing can happen to older power supplies esspecially when they're used with newer hardware. It's just wear and tear of the thing. Luckily they're not that expensive :)

Good power supplies are expensive.

my power supply has caught fire twice and i still use it even though it's full of tape and a load of other junk :P

If the computer was properly grounded, there should be no dmg at all.
If not, there is a slim chanse something might have been electrecuted.

The smoke is usualy when plasic melts around wires, so don't worry.
Just a short-out and some heat.


Had a mushroom-cloud prom my monitor once.. well... it didn't realy work after, but it was an impressive display.

I've replaced many power supplies at work and at home, but always on friends computer, never on my own computer.

Mostly reason for power supply to burn is dust, which helps heat accumulation. Very often same dust shuts down fans, again overheating the power supply.

If nothing melted, open it, replace fan, clean it, check the fuse and check if nothing burned. Then try it again.

thanks for all the replys guys. I dont think im gonna mess around with the old power supply especially cuz I dont know how to fix them, plus standard case power supplies suck. I had problems with it before it blew up and stopped working. Whenever I was playing BF 1942 it was run for 5 mins and my comp would turn off, for some reason I never thought it could be the power supply.. I actually was thinking it was my video card but that it running 100% fine. Turns out I needed a new one anyways and if all is not ok, this may have been a good thing hehe.

Not many people understand how important PSupply is to your comp. Mark my words. :ok:

My old compaq deskpro 2000 was stuffed so i was testing out some harddrives and cd-rom drives i got for $20 bucks i had it all pluged in and powerd it on it crakeld ant pwer pack and one of the hraddrives started smoking lots man it stunk

LOL I recently have had two comps psu go My Main Pcs one went a Expensive one but no damage to the pc & a old PII i was fixing up it wrecked the mobo and mucked up one of the sticks of RAM.

Expensive PSUs are good and honest with the Wattage but cheap ones are obviously easyon the pocket. 5 rubbish ones or one good one?
