iMac 24" A1200 power supply pinout?

Hi all!

a friend of mine gave me a broken imac 24",

and i would like to recycle the power supply for another project,

however i don't know the pinout, well i could easilly find the Vcc with voltmeter,

I just need to know which pin will switch on the unit,

and if it's a "connect to Vcc" or "connect to ground" system

5- 0v

6- 12,1

7- 12,1

8- 25,3

PIN 1/5 => O volt

PIN 2 => 3,3 volts

PIN 4 => unknow

PIN 6/7 => 12 volts

PIN 8 => 24 volts

PIN 3 is connected to what seems to be a temperature probe

my conclusion is this PSU has no switch ON/OFF,

it is always powered up

It's been a few days now i'm using it on both 12/24v, and nothing to report
