The fat PS2 converts AC to DC like any other PS2 or gaming system. The power supply itself does the converting. the fat PS2 converts 110Vac to 12Vdc. All you have to do is bypass the AC transformer, rectifier, and filter caps to get to the +12Vdc Regulator. It all depends on what type of alignment your going to have with your PS2 and where your going to mount it.
