Power Supply for Powermac MDD

If eBay is too much pricing heartburn, try a Mac User GFroup (MUG) in your area. This site will help you locate one:

Typically, you don't have to physically visit the groups to get help. Many times simply sending a "looking to buy" e-mail to the groups' published addresses will get a response.

The other option is to look for a working MDD and use it for parts. The cost of a cast-off computer may be less than the PSU.

You can convert an ATX PSU for use on a G4...

That link would not work for me but I just checked in one of mine and the MDD had the long thin rectangle shape. I think anyone would have a hard time finding that design with standard ATX pinouts. I bet that link was for a Quicksilver

With all due respect for your excellent and long running work on this forum the link you gave(this time they worked) only showed the correct pinout for an adapter. The problem remains of finding a supply that will fit in the machine and allow the side to be shut. The heat sink is right in front of the power supply that when shut only leaves only a tiny gap. Unless he wants to use an external power supply, he has a major problem with fit. We would have to find him a PS that would fit and have a standard atx pinout. The only other way that I can think would be for him to really mod the machine with water cooling. Some people did it and that might free enough space for a standard square PS if you could route the hoses just right.

Ah, I see thanks. 🙂
