The Power Macintosh 7100 was one of the first PowerPC based Macintosh systems released along with the Power Macintosh 6100 and Power Macintosh 8100. The 7100 was released in March 1994.

The 7100 was replaced by the Power Macintosh 7200 and Power Macintosh 7500 models.

General Information


The PowerMac 7100 is based on the PowerPC 601 processor with available speeds of 66MHz and 80MHz.


8MB onboard RAM. The system is expandable to a total 136MB.


The PowerMac 7100 is a NuBus based Macintosh with three expansion slots. There is also Processor Direct Slot (PDS) expansion, typically used for a standard video card or AV card for the AV model.


  • The PowerPC 601 processor is very fragile and putting too much weight on the heatsink may actually crack the CPU.
  • The 7100 model in particular is said to have poor heatsink compound and the system will likely overheat unless the original compound has been cleaned and replaced.


Capacitor replacement

The SMD capacitors on the logic board will most likely have already started leaking electrolyte out the bottom, and failing to replace them in a timely manner will result in further leakage with possible damage to nearby components. See below list of capacitors to replace:

  • 25 x 47uf 16V
  • 1 x 100uf 6V
