I can´t believe this isn´t on in the product specs! I´m currently in Chile, trying to figure out what the wattage is so I can get an appropriate transformer and the maximum wattage use isn´t even in the specs. The cinema display specs were pretty straight forward at 90w, but no wattage listing at all for the G5. I´ve already fried one power strip trying to get this working, so I´m pretty nervous and want to get it right the first time. That´s a pretty major oversight for Apple. Specifically, I´m looking for the maximum wattage use for G5 model number M9457LL/A. Any help, especially quickly, would be greatly appreciated.

thanks much,

    What is your line voltage? The G5 specs are:
    "Line voltage: 100 - 125V AC or 200 - 240V AC (wide-range power supply input voltage)."

    Do you need a transformer?

    The specs are a little baffling. I had always thought it was about 700 watts so I looked it up and here is the statement from the Apple PDF.

    Electrical and environmental requirements
    • Meets ENERGY STAR requirements
    • Line voltage:100–125V AC or 200–240V AC
    • Frequency:50Hz to 60Hz, single phase
    • Maximum current:6.5A (low-voltage range) or 7.5A (high-voltage range)
    • Operating temperature:50° to 95° F (10° to 35° C)
    • Storage temperature:–40° to 116° F (–40° to 47° C)
    • Relative humidity:5% to 95% noncondensing
    • Maximum altitude:10,000 feet

    Use a 1000 and that should cover it. (The Mac Pros are about 1200 Watts?)
