    Hi,

    usually I found this kind of "performance" at apple-history, but the last model with info about wattage is the Power Macintosh G5 (which power consumption is approximately 700 watts).

    Can someone please tell me the actual Mac Pro's wattage?

    Thanks in advance

    :D

    Whew, was that quick!

    So, let's see, compared to my upgraded 1,4 GHz G4 with 200+ Watts running dayandnight a Mac Pro with 1000+ Watts forces me to become a treehugger and save some energy. :p

    When the Mac Pro is asleep, it does not even register on UPS' or wattage meters. Just let it sleep a lot.

    and remember, it's not consuming the rated wattage all the time, in fact rarely ever... I'll plug my KILL A WATT meter into my MacPro later tonight and get you some accurate measurements of power consumption.

    I was curious about my :apple:TV a while back because you can't turn it off, but it wasn't so bad: http://forums.macrumors.com/showthread.php?t=467027

    You guys seem to be ill-taught in PSUs.

    The Mac Pro has a 980watt PSU. This means that the power supply can provide the system with up to 980 watts. Too bad Apple put a ****** psu with crap efficiency of only about 70-75%, very low quality.

    The Mac Pro will use about 200 watts on idle with 1 GPU, and around 375 watts on load with 1 GPU, and two hard drives. When you max out the system in terms of hard ware, it could use up to 350 watts on idle and 700 watts on load.

    Remember that just because the PSU can give that much power, does not mean that the system always uses that much energy.

    What I am hoping for is that the next Mac Pro will have a re-designed PSU with over 80% efficiency in converting AC to DC. Many PC manufacturers are jumping on the energy efficiency boat, but Apple seems to be lagging and installing low-quality, power-hungry PSUs in its desktop machines.

    Apple has the power consumption and heat output values listed on their websites for just about any machine made in the past eight years.

    The power consumption of the Early 2008 Mac Pro (Octo 2.8) is 155 watts at idle, and 318 watts at full cpu utilization.

    Well, andypress and dimme were spot on... but I had to geek it out and make a video with an inlay video of the KILL A WATT as it measured the watts in realtime.

    See for yourself: http://thatsawesome.tv/mac_pro_wattage.m4v (4:17 and ~50mb)

    A VERY efficient machine if you ask me! And Apple's numbers are right in line. I am at 191 watts as I type this.

    But your GPU was asleep when you did these tests. And GPUs are unfortunately real electricity eaters. Maybe you could run a Game like Crysis (I think crysis can support 8 cores)

    Well you may or may not know this... but Aperture is very heavy on the GPU. I also did some tests with Motion, also very intensive on the GPU and it never got above 315watts.

    Like the Apple doc andypress pointed out above, their numbers are right in line with what I found out.

    FYI... it draws around 1.6 - 2.0 amps
