    I took a few power consumption measures at home and was surprised to note that my Mac Pro 2006 (with 16 GB of RAM) consumed 55W, whether in sleep or standby ("off") state.

    I knew part of the logic board had to be powered even in "off" state as the power-on can be programmed, and I knew FB-DIMMs consumed more power than regular RAM, but I was still surprised to see such a high consumption in standby and no difference with sleep.

    Is it the same with you? Is it the same with newer Mac Pros? The power consumption of my Mac Mini in sleep mode does not seem to reach 1W.

    Some measurements.....

    I done time ago give me between 45-125 W, in the operating modes you described. But I live in area with too much fluctuations in the power grid.....:confused:.....:eek:

    what method did you use to measure the power-off mode?

    If it is off, then it is off and it should be about 1.5-2W.

    My Mac Pro is 5W asleep and 90-110W idle.

    I checked the power consumption with an induction power meter and off or sleep, consumption is 55W

    Well then you have an issue because it SHOULD NOT be using 55W when off/shut down.
