i wouldn't say so.

It would trip the OC protection IMHO.

You mentioned that it does work fine for few minutes. So turn it on without the mb and check all the rails for out of tolerance voltage. Including low power -12 and the like (not sure what imac voltages are)

if they all are fine, try plugging it to mb starting the computer and check which ones are out of tolerance. But limit the time for that as it will bur again.

I had a psu where i shorted -12 rectifier and was unable to spot it as it was under a big choke. It did not have oc protection and it would burn the primaries upon the start up.

I dont know how to test the -12v, theres only +12v and ground, could -12v be shorted to ground, or is it normal ?

I am not familiar with imac power supplies.

Are you sure it only has 12V output? no standby voltage? no other outputs?
-12V was given as an example.

Check voltages as they are without plugging to MB, then with plugging and so on.

I was getting +12v on standby,i tried other brand mosfet and its dead now. I´m currently looking for a cheap replacement psu. Are all a1225 imac psus compatible with each other ? Or i need same psu as old one ? Do you know where i can get a psu for it? Preferably in EU.
