Hi everyone
Just got (another) Power Mac 8200, that also doesn't work.... wanted to start with the PSU. Does anywhone know if this PSU can be started like a regular ATC by connecting 2 pins? and which ones? Tks in advance
 
The logic board has a whole pile of SMD electrolytic capacitors on it. You'll need to recap it and the power supply before using it.

If it's not powering on, then it has capacitor issues at minimum.
 
Yes must probably I need to do that. But wanted to be sure that PSU is working
 
Catch-22. Without good capacitors, you cannot test the power supply.

All Macintosh computers from the original 1984 model to well into the 2000s are now suffering from capacitor failure. Recapping them is a requirement, not an option.

Powering up a power supply with bad capacitors can cause hideously expensive damage from leaked electrolyte creating shorts to places where none should be. I know, because I've had to repair such units from people that didn't know any better. It gets very expensive very quick.
