| Mac IIci PSU compatible with PowerMac 7100? |
Posted by: cadenya on 2021-08-29 17:14:28
Hi, I have a IIci with what I think is a dead PSU (no power, completely dead) and I need to either recap it or get a new power supply. It just so happens that I have a PowerMac 7100, and according to this website https://applerescueofdenver.com/pro...50-700-iivx-iivi-performa-600-power-mac-7100/ the power supplies are compatible.
Does anyone know if this is true? I don't want to fry my IIci motherboard by accident. Thank you! |

Also right in the title... "Power Supply ... IIci..." |

Also right in the title... "Power Supply ... IIci..." Yes, but I saw that there are 2 options, one for the IIci and one for the 7100. One is 108W and the other is 112W, for the IIci and 7100 respectively. Should I test it out? Will the 4 extra W hurt the computer? |

Will the 4 extra W hurt the computer? Nope, just means it can take a tiiny bit more load, I can't really think why Apple would've specified that the 2nd revision was uprighted slightly. The difference between the two isn't the pin out, it's just that the 2nd one is a later revision, so it will work fine. |

Also, the IIsi power supply will work on all the machines that the IIci/IIcx power supply works in.
I wouldn't try to operate that way as a habit (plus I don't think it fits the cases), but for testing things on the bench, it can be handy -- especially if all you can find at the moment is a IIsi power supply. |

Ok so I tested the PowerMac 7100 power supply inside my IIci, and it does indeed work fine. Thank you everyone! |
