PowerMac MDD PSU

After doing some extensive reading on the “Wind Tunnel” Macintosh machines, I came across several ideas on what to do. What i did was take a regular ATX PSU and mod it to fit inside the guts of the flawed Apple MDD PSU design. And this was the outcome i got.


It works like a dream, the only drawback is that there is no +25V for the ADC internal connector for the video cards that run the Apple ADC monitors. I shoehorned an Enermax 460W PSU into an MDD PSU housing.

Here are some worth while links that helped me out…
