    I have a G5 1.8 single (4 ram slots) and the power supply is/might be going out and I found a good deal on a 600w power supply (Apple Service Part Num: 661-2904, OEM AcBel API-2PC54) the one in the G5 currently is the 450w AcBel can I do this without issues? Thank you, Jeff

    As far as I know, the original spec for your machine had a 450w, but I don't think there should be any issues if you put in a 600w as long as it fits.

    When I had my G5 I remember reading that the single processor machines used a 450W PSU while the dual processor ones required the bigger 600W PSU.

    I have read that my Mac Pro uses a 1KW PSU :eek:
