    I was wondering if an 85W power supply from a G4 Mac Mini would work with an Intel Core 2 Duo model I acquired today. Many sources I ran into claim that both 85W and 110W power supplies work with the G4, but the 85W does not with some Intel models, and many other sources claim that 85W works either all or early Mac Mini Intel models.

    I have the August (Mid) 2007 version of the A1176 model, and 110W power supplies are not cheap.

    Will an 85W power supply work with what I got?

    It may work, but it may not be worth the risk.

    If you mean risk as in damaging something, then that shouldn't be possible since it is only 85W, right? But if you mean risk as in wasting time and money, I understand.

    You could damage the power supply, the internal charging circuits, or the any number of internal parts.

    I see....

    I guess I'll just try to find a power supply on eBay for cheap. Thanks, bud!

    Data risk. What do you think happens if the CPU tries to pull more current than the supply can deliver? Voltage regulation dropouts, unpredictable CPU and/or RAM malfunctions, possible HD malfunctions, possible data loss.

    Hardware risk. What do you think happens if the power supply is run at or exceeding its maximum rated output, for potentially extended periods of time? Excess heat, excess current, might even blow an internal fuse.

    No it doesn't. When I bought my Intel Mini, I just did the simple thing of connecting it to my G4 Mini's power supply and it didn't work, ie when I tried to turn the new Mini on, nothing happened.
