iMac 2006 ATX 'conversion'

[128keaton]

Hello! I received a free iMac with a dead PSU. Ordered a new one, taking eons to arrive. On these acrylic models, the PSU hooks up to a board which does most of the 'heavy lifting' as far as power distribution goes. Going to the board (via a molex-esque connector) are 5 wires, 12V, 12V, GND, GND, and PWR_OK. I simply cut off the connector from the old PSU and elongated the wires with some wire of a similar gauge. Then I grabbed a junk ATX PSU (doesn't supply enough voltage though the ATX connector) and chopped off two molex connectors, for their 12V/GND. Soldered it respectively (white/yellow to gray, black to GND two times over) and left the PWR_OK line to itself.

Powered up fine and went on its merry way .

The last time I soldered something I fried the audio board on an Amiga monitor.

Yeah, that's why I don't solder, let alone do wiring like you did.

Glad you can though. Good work.

Bad pic, but here it is installing Lion!



Happy iMac! I've got 4GB of RAM coming, and downloading Mountain Lion to install
