I take it you have the TEC already right? Can you measure it, if it's 50x50mm then it's most likely a 226W TEC, if it's 40x40mm then it's an 80W. Another thing even if you have a spare computer PSU, most require a bit of load on its other rails to function properly.
Heh I'm a big fan of eBay and you can find plenty of 12-15V PSUs there if you look hard enough.
Good thing you didn't stick it in the wall, that thing could blow up!
