It does sound like the PSU is fried.
If they happen to be the same type, you could swap the PSU with the one from your Wife's PC to see if it boots properly.
Either that or get a new PSU from a retailer. They only run a few bucks so you're not going to be out of pocket even if it's not the PSU.
Actually if it's not the PSU then you could just take it back to the shop and get your money back.
