Power Supply (PSU) pin-out diagram

I’m looking to try to drive a non-Mac Mobo off this PSU. I need a pin-out diagram. I see one for the Mobo end of the 2389 version but I don’t have that iMac, and I can’t check which Mobo pins connect to which PSU pins, so it’s useless to me.

Anyone know where I can find a pin-out for this actual PSU (the label on it has the part number 614-0445)?

Is this a good question?

Kevin Pattison  as you have probably already figured out, Apple suffers from total paranoia and delusions of grandeur. All of their schematics etc. Appear to be managed through “For your eyes only” security cleared personnel. Anybody violating their NDA will be punished to the full extend of the law, which of course is fully supporting companies like Apple. Support this to stop the insanity. Anyhow, enough of that.

The PSU is a Delta ADP-200DF and a search on that may reveal more. In the meantime, I would use the pins listed for the test points. Use your multimeter to measure those on your actual PSU:

Pin 1


Pin 3

5V power for Hard Drive(s). Note: If present, the 12V power will come directly from the Power Supply to the Hard Drive thru the power harness cable.

Pin 4

Standby 12V power (permanent power coming from power supply, present as long as AC cable is connected, even if computer is off)

Pin 6

Backlight Control pulse width modulated signal (from logic board to LED backlight board, to adjust the backlight level setting according to user setup)

Pin 11

12V Run-Mode power to logic board (coming from power supply, present as long as system is on or asleep)


Power On Request signal (from logic board to power supply when power button is pressed)

Pin 13

Backlight Enable (signal from logic board to Backlight Controller board, to enable backlight)

Pin 1 should be marked on the board. If you have any difficulties with that post some images of your PSU with your question. Adding images to an existing question

Could anybody show a picture how to connect e.g. a HDMI driver board to the PSU? How can I use the 12V output from the PSU and where would I attach a cable to it? From the images provided, I can not figure out how the PSU could be used for that purpose.
