My 10 year old newphew was messing around with my PC and switched it from 220v to 110. The PSU burned out and the PC will no longer boot, but I am hopeful that only the PSU is burned out.

If I replace the PSU will the PC be okay, or is it likely that the whole machine is fried?

most probably just the fuse in the psu has blown, so that other parts havent been damaged.

shrex is right. All PSUs come with a fuse so that it does not catch fire in case of short circuit, brownout or over-voltage. There is a possibility that your machine could be fried but that is very unlikely. Replace your PSU and all should be fine.

Purchase PSU that does not require voltage switch. Corsair is a start.

LOL, I was thinking the same thing. Not sure how switching it from 220 to 110 would kill it, but getting a new PSU that doesn't care (much) about the input voltage is a great idea.

Speaking from second-hand experience, it will.

I live in Saudi Arabia. The houses in my compound are wired for both 110 and 220 volts. I replaced a PSU in one of my friend's computer when she moved it from a room wired for 110 volts to a room wired for 220 volts. PSU fried. It did not blow the safety fuse.

And yes, I know that 110 volt and 220 volt outlets are supposed to be different.

In my house, one of the wall outlets in my computer room is not grounded properly. If you were to plug in a lamp or clock radio, you'd never know.

Thanks everyone for the very quick replies.

jsc, you mentioned that it did not blow out the safety fuse and yet the machine functioned after replacing the PSU?

A quick update: Although I realize it is somewhat ill-advised to do so, I opened up the PSU and sure enough found a blown fuse. Guess its time to go shopping for a new one, alikum suggested corsair, any other brands? Thanks, I am not really a hardware guy

Just to jump in here a little bit: As alikum said, it is nice to have a power supply with Universal Input, so there's no switch on the outside of the PSU to change the voltage - the PSU does it all automatically. Many of Antec's PSUs, for example, have this feature standard. When shopping for a new PSU, make sure you look for the "Universal Input" feature.
