I'm fixing a PowerMac G4 for my Dad's wife.
The original PS is dead.
It was a pretty standard ATX supply, the only difference is that it
supplies 28VDC at 4 Amps on two extra pins. Rather than spending a
lot of money on a new supply (more than $250 from the few sources that
will guarantee the PS) or a not insignificant amount on a used PS that
could go at any time, I want to put in a new standard ATX supply and
"tuck in" a small 28VDC PS to drive the two extra pins. The supply
is always on, so I can power it from a pass through on the ATX supply.
Does anyone have (or know where to get) a small supply?

28VDC at 2A:
