Re: imac G5 Celetronix P/N :614-0363
I don't know much about them either Plus it's my father-in-law's mac, so I *really* don't want to fry it
The picture of it matched mine, so we'll see. No information about whether it is Delta or otherwise, so we'll see what turns up. Too late now, it's bought and paid for.
The price of new units is shocking. How can they justify that for such a simple PCB?

Re: imac G5 Celetronix P/N :614-0363
I've bought a replacement 614-0363 from flea bay. Supposed to be in good working order. Still, I hate not knowing how things work so if there's anything you want me to test while this mac is in bits, then let me know

BTW, the imac in question is a 20" Intel Dual Core.

As far as I can tell, nothing is coming from the MB side. There's seems to be no battery inside the mac other than the CMOS and I'd be extremely surprised if that is being used to start the PSU.
I suspect that the PSU is being activated in a similar way to an ATX PSU.

Yeah, that's what I wanted to do, but I'm not sure how to get the MB to turn on the ATX supply.
Gimme a sec to check what's happening on the MB side.

Forgot to say: the PSU works occasionally.
The above values were taken when the imac would not start up.
The imac just entered a working phase and I tested the PSU again. Only difference: the voltage between brown and black went down to 5.6V, with occasion spikes (weird I know).

Re: imac G5 Celetronix P/N :614-0363
I am getting 12V between the grey and black with the PSU unhooked and unjumpered.
And 8.7V between brown and black....
