The Mac II and IIx used one version of the PSU; the "real" IIfx used a revised version (with variable speed fans?). Part numbers are:
661-0375 Power Supply Mac II, IIx 120watt
661-0542 Power Supply Mac IIfx
In practice the PSUs are interchangeable. Does anyone have a parts list for the II/IIx --> IIfx upgrade kit?
