One by one, my MDD G4 collection has seen their power supplies fail.
It seems the exact form factor is not available as a new product, only
used. Which is tough, as it would probably fail soon anyway.

Anyone have experience replacing these? Any advice on best model to fit
inside the MDD case?

I bought an ATX 400W supply and waited to start the conversion process. Now
that I tested it, it's a DOA. My mistake waiting so long, but though I'd
ask here before throwing more money at this.

I have one with a dying Power Supply as well. I've been researching with
Google and one guy has a write up where he carves up the existing PS case
and install the guts from an ATX PS into it. It looks pretty good when
he's done but it's not for the non-technical user to do. I've also seen
people just tie strap an ATX into the case and splice the motherboard
connector from the old power supply onto it. Not elegant but workable.
ATX power supplies don't have the 25 volts needed for an ADC monitor but
most people don't use those anyway. If you do need it there is a guy on
ebay that sells rebuilt original MMD power supplies. Not cheap but a
fair price.

FWIW,

I put an ATX 500 Watt unit ($25 new from Amazon) in my Mystic. I'd
say you don't need to worry about the size and mounting holes as they
seem fairly standard/compatible, but should be concerned about the
orientation of the power plug, fan outlet, and wiring harness. Amazon
had several units/models to choose from. Also, ATX doesn't have the
28 v lead which I didn't need as I'm not using an ADC monitor. There
may be other issues with the MDD that I'm not aware of like waking
from sleep,,, YMMV

Hey Joe and others:

There is a New York company that rebuilds/repairs the G4 MDD power
supply. Just use Google to search for New York, G4 MDD, rebuild Power
Supply. They want about $80 for the job.

All things considered, I bet it's less time and expense to just get a
rebuild as mentioned above. However, I've been wondering if these
would fit or could be made to fit:

Thanks for the lead, but the one new york place that results has a note
they don't do this any more. I'll keep looking.

Looks like a good shape but it's a used supply. If I'm going to buy used,
I'd try to get the exact form factor with MDD voltage pinout.
Right now, I'm leaning towards http://atxg4.com/ for the adapter, and just
trying to find an ATX supply that makes sense. I'm willing to pull the
optical drives out and drill holes to vent out the side if I have to.

Sorry to hear that. Maybe time for an earlier G4 or a G5?

Well, I have 4 dead MDD G4s, and would still like to get 2 working. I'd
upgraded over the years, and even have a couple SATA cards in two of them,
it would be a shame to call it quits.

According to their website National Ram Electronics no longer repairs
Apple power supplies except for ones that are still under their warranty.

Spoken like a true Lowendmaccer. Viva Le Machina!

If you are willing to do some work and figuring, the group at www.Badcaps.com
have helped a few people to fix their own G4 MDD power supplies. It
may take a while, but they are very patient and helpful. You have to
join, of course, but that is free and I never got any spam from it.

Good luck, again. Bob
