  1. 1. I bought MDD G4 for $40 but looks like PSU just died, is it worth to repair the PSU or should I resell it for parts?

    • Find someone to Repair the PSU
    • Sell MDD G4 for parts

I thought it was quite difficult to repair and diagnose a MDD PSU, due to multiple point of failure (unless you're an electronics tech!).  If a nice dual CPU model with good GPU I'd keep it, otherwise look for a replacement PSU

Ditch the PSU, replace it with a stock ATX power supply and one of these adapters; http://atxg4.com


Specifically this kit. http://atxg4.com/mdd.html


QUICK EDIT: You might have to contact the maker at his Etsy store, since it looks like he's out of stock for the pre-made MDD ones. But that guide should tell you how to rig up your own if you've got the courage.

What nglevin said. Just install an ATX PS.

I replaced the PS in my MDD G4 twice and was ready to scrap it when the stock PS failed for the third time.

However, I decided to try the ATX path and it worked like a charm!

Follow the instructions here: http://atxg4.com/mdd.html

I didn't use a mod cable I just rearranged the pins using the proper molex extraction tool. (Without which it's basically impossible to remove the pins.)

I did have to use an 24 pin extension cable to be able to mount the PS inside the top of the case.

Also, I haven't had any issues with "deep sleep" although I usually power it off when I'm not using it.
