All PSU's should accept a standard ATX plug, the cable it comes with might be different though to account for different countries sockets. Just buy an ATX cable compatible with your countries wall socket or use a spare one.
Thanks a lot--I never thought of that! *Slaps forehead* I just ordered a 13A 2-pin to 3-pin adapter. It's aligned horizontally, too, so my plug will go in in the regular rotation which is nice. Can't be arsed to buy a new cable! Thanks for your help!
