If you are talking about a three phase 220Volt in the USA, You have a problem. I do not know how you managed this since the outlet would be significantly different to prevent this from happening. Assuming you somehow managed this, you definitely fried the power supply, but there is little you can assume about whether any higher than normal voltage got past the power supply before you fried it beyond use, unless you take out the power supply and put in a known working power supply and try the system out. If you get nothing then the motherboard at least is gone. If you get something but not normal, you will need to do more testing.
You have to be a little bit crazy to keep you from going insane.
