    Hello

    Just out of interest I've been trying to work out how much energy a mac pro uses in comparision to an iMac. According to Apple power for the 24" IMac is a maximum of 280 Watts. OK fair enough.

    For some reason they don't list this figure for the Mac Pro. It is listed as:

    Current: Maximum of 12A (low-voltage range) or 6A (high-voltage range)

    So using the formula W = V * I [W is power in Watts, V is voltage in Volts, I is current in Amps]

    That means that potentially the Mac Pro (without a display) can draw:

    230 * 6 = 1380 Watts (UK)
    110 * 12 = 1320 Watts (Europe / USA)

    An Apple Cinema Display is another 65-150 Watts depending on size.

    Is that right or am I going nuts?

    Thanks

    Potentially yes, the Mac Pro PSU is rated for 1000W. It will draw a little more that that at the wall socket for various reasons (inefficiencies).

    However, i'm sure others will tell you in more detail, but the MP will NOT draw anywhere hear HALF of the max wattage in the standard configuration.

    Probably around 300w on the base config at full load, and around 700w if you maxed out the 8 core with 16GB of RAM, 4 hard drives X1900XT.

    1000 Watt PSU, that's interesting - Thanks for the info.

    Basic 'net surfing, adium, etc. only I consume ~150 box only

    add the powered speakers and 20" ACD and it goes up to ~175

    others will be able to give you much better stats on intense usage–I rarely push my 2.66 quad over 60%
