Power Mac G4 MDD Power Supply capacitor list (Samsung 360W)

Power Mac G4 MDD Power Supply capacitor list (Samsung 360W)

This project is a work in progress but I thought I’d share what I have so far. I finally set out to map the capacitors in an MDD PSU so that we can see about recapping it. Currently on my desk is a Samsung PSCF401601B(C) Rev: A & Rev: B 360W power supply. This came from a FW800 MDD and is a revised model, Apple shipped the first MDD’s with a 400W power supply that ran hot and was super…

Recapping an Xserve G5 power supply – Part 2 – Recap and test

This is a continuation of “Recapping an Xserve G5 power supply – Part 1 – Preparations” so read that first if you haven’t already 🙂 Received some capacitors today! I put them all in place (not soldered) to see if I got the right sizes and here is the conclusion: 1. C111 – 1000uF, 16V – Perfect fit 2. C112 – 1000uF, 16V – Perfect fit 3. C104 – 2200uF, 16V – Too big 4. C103 – 2200uF, 16V – Too…

Recapping an Xserve G5 power supply – Part 1 – Preparations

A few weeks ago I picked up a whole stack of Xserves. I had been looking for a first gen G4 Xserve which has the tray load optical drive instead of the slot load and the rest of them were believed to be all G5’s.
