The internet is full of good information so I went for it.

I found a post on the internet stating that a 300W power supply should be sufficient without the Apple Display. I haven't tested FW800 because I don't have any FW800 devices. It's day two and everything is working fine so far including DVD drive and firewire 400. I used an APOLLO 300 Watt Micro ATX Power Supply. I have just converted an ATX power supply to work in my G4 MDD Dual 1.2 FW800. Unlike the ATX standard the MDD logic board does not have a pin for PWR_OK and -5V, so you can leave them unconnected.Īlso note that the psu needs to have a really strong 12V line (10A+ recommended) and it can not be any higher than 7cm to fit inside the MDDs case. if in doubt, use the pinouts on or wikipedia as reference. Use the broken psu for reference as the wire colours will match in most cases. if you don't wanna void the warranty of the new power supply, buy an adapter for 20->24 pin ATX and tinker with that to match the pinout. What ponders me though is that the integrated fuse will not blow, though it is rated much less than the breaker.īe careful when using a new atx power supply! the connector will fit but the pinouts are different and you my end up frying either your logic board or the new power supply. I tried analysing the defective psu but neither rectifier, capacitor or anything else on the primary seems broken, the breaker kicks out as soon as i connect it to my wall outlet. I also happen to have a 1.25GHz MDD with a failed PSU and i am now using the atx psu of a broken Maxdata desktop PC.
