Power Mac G4: Need power supply

Hello all another new guy here, I could'nt figure out how to start a thread but I do need help. I have a Power Mac G4 with OS 10.2.8. My power supply went out and the number is API-9841-291.
Now does the last 3 numbers make a difference? API-9841
As long as its 22pin connector right?
Or it has to have all of the numbers for it to work? API-9841-291
Does anyone have any idea about this?
Thanks

Google is your friend - i found this, any help to you?
