Power Mac G4 Gigabit PSU repair, no power
Posted by: alectrona6400 on 2024-06-02 10:15:43
Hello... I have a PowerMac G4 Gigabit model with an AcBel PSU that does not power on. The capacitors don't seem to be leaking or bulging but I'm getting absolutely nothing out of the PSU. Apparently theres a guy on eBay doing repair services for these power supplies but I don't know what he is doing to fix them. Has anyone fixed the AcBel PSUs on these and how was it done? I would like to keep ADC power.

I have repaired several of them, by replacing capacitors. The fans can usually benefit from some attention as well.

do you have a cap list for the AcBel API-9841-291? I have to recap one of these myself

There's one here, although I haven't verified it personally: https://caps.wiki/wiki/Power_Mac_G4_Digital_Audio_Power_Supply

Im looking at that one, I think it should be it, although it appears they made the same psu with slightly different labelling, which is causing me confusion.
