PMG4 Quicksilver PSU clicks when shutdown only.
Posted by: Alex on 2017-05-09 09:15:58
Hello

I have a PMG4 Quicksilver whose power supply (PSU) emits some clicking noises while it is shutdown but plugged into the wall outlet. When the machine is running I can identify the same clicking. The machine otherwise works as expected.

I would like to replace the PSU but am wondering if I can replace the PSU from another PowerMac G4 model or if the Quicksilver PSUs were unique to the extent that I can't just use a different G4 model's PSU.

Kind regards

—Alex

PS If you would like me to make a recording of the audio clicking I can do so but at the moment the environment is too noisy to isolate the sound.

I'm pretty sure different models of the PMG4 have PSUs that are wired differently, someone correct me if I'm wrong.
