Re: PowerMac Dual 1Ghz Mirror Drive Pop&Burn Power Supply

Hi All.
I'm trying to repair the same PSU with the same problem - "Mains cap, fuse, both switchers (Q1,2)" Can I replace swithers with W20NM60FD? I've read datasheets on both W20NM50 and W20NM60FD, it looks possible except R(ds) - 0.25 and 0.29 respectively? Or is it not so important?
