Re: 2009-2011 Apple iMac 205W Power Supply Pinout?

HI all . I have a Imac 24" The guy who gave it to me didn't have it protected by anything, and it got hit by voltage spike. After taking apart, I realized the Fuze was blow, I replaced. It blew again. Its hard for me to find a Power suply local to test if anything else is bad. So I grabbed a PSU from a old G5 MDD tower that was int perfect working order. I am making a adapter to run the unit.

The problem is all the cables are BLACK!!!!!! what a dumb idea. I mean they have to make it look nice on the outside, but really. whats the point???

So far I have found the following pinout.

1,3,7,8,14 Ground

10,11,12,13 12v Because 1 of the pins goes to the Inverter board for the Display and it says 12v inout 63v output

2, unkown, but its a Small thin cable going to Mobo, and the Trace on the PSU goes back to and unkown area on top of PSU passing the vari-sistor

4, Has a heavy duty trace going to the Center Post of 2x paralleled T03P (Note: it seems the output of the T03P goes to Power 10,11,12,13 pins)

5, Goes to a trace on the PSU that seems to switch on the two T03P Mosfet after hitting a tiny transistor.

6, Goes to same area but after several mini Filters and Resistors it returns to the input of the mosfets,

7, Ground leads back to the area of 5 and 6,



any help to get the power on the MOBO so i can test the rest of the unit would be greatly appreciated.

Is that the square, open frame one with the corner chopped off where the connector is? Is there an Apple PN on it?
