Fried Power Supply?

We had a guy at work get too excited to hook his computer and pluged it into a 220V wall socket. The power supply was set to 110V because before we moved it had been in a 110V socket.

Now that we switched the power supply over to 220V and got everything plugged it, it doesn't do anything. Just to clearify, the power switch on the power supply was on, but the power button wasn't pushed.

my inital thought was that he fried the power supply, but it didn't smell like electrical burns usually do and there was no smoke or anything. Please let me know if you think he ruined the power supply of you think the over age of power may have shorted the mobo.

Did you try to push the power button? (from what you wrote, it looks like your saying that you plugged in the computer, than switched the 220V, but didn't push the power button) If you did try but nothing happens, well what you should do is try to find out what fried. You can test your mother board with an other PSU, and test your PSU with an other computer to see wich doesn't work. Hopefully its only your motherboard that fried, and not nothing else. Good luck, Cheers :D
 
Ok, I was trying to wite a lot of info too fast. We did try and turn it on, but nothing happened. I don't know if anything fried because it I thought I'd be able to smell the short. I can't actually change anything on the computer, because it's a government computer, but I don't know a lot about the differences between 220V and 110V. I'm american stationed over seas.
 
I know that if you try to put to much voltage in a device thats rated for a certain Voltage, chances are that you put to much power. Either the PSU was able to handle the voltage, but not the motherboard, or the PSU burnt out.

Even if you didn't see any smoke or smell anything, on the motherboard there could easily have some damage in the smaller voltages (like the 3.3v for exemple), since that 3.3v isn't alot, you wouldn't detect much if anything happens. So in short, thing can still fry with just little power (even a little static electricity can damage a motherboard, things to look out for).
 
So you plugged a 110v powersupply into a 220v plug without switching the dial and turned the computer on, right? If that's the case, i would guess the psu is screwed.
 
Well, I didn't. It was a guy at work too excited to get his computer setup in our new location. He's, to say the least, special.
