iMac (21.5-inch, Mid 2011) Power Supply Type?

[blueyedsamurai]

The Office imac seems to of died and there is no power at all. No sounds or lights, I've also tried all the fixes and tried another power cable and outlet but no success.

The power supply's are pretty expensive so before I order one I was just wondering what exact type I would need to get?
