    Okay, here's my personal power usage spreadsheet. This post will be updated as often as possible.

    Preliminary considerations:

    1. The Kill-a-Watt I'm using is around 20€, so I guess it's not very exact in it's measurements. It should be, however, usable to get an idea or trend of usage.
    2. Windoze idle usage is somewhat skewed since one of the GPU cores isn't ever falling into 2D idle state.
    3. I'm running 4 VM's, WinAFC helps assigning 7 threads to the VM load and one to GPU load.

    System components:
    PSU Antec Signature 850w
    DFI X58-T3eH8
    i7 920 @ 4.2GHz 1.325 vcore 1.42 vtt
    12GB DDR3 1600 7-7-7-24 OCZ memory @ 1.66v
    oldie Audigy, two hdds, two odd
    one DDC 3.2 pump, 9 fans total

    GPU
    1x GTX295 single PCB, stock volts air, fan 100%, CSM: 630-1548-1107

    Windows idle 285w

    Code:
         |  VM1      | VM2      | VM3      | VM4      | VM base load |  GPU0         | GPU1         | resulting wattage

    Notes:
    - 353pt WU seems to fluctuate alot, maybe because it's not fully loading the GPU all the time?
    - A1's draw less power, but maybe that was obvious
    - Apparently there aren't many data points needed, as all the values seem to be in the same ~50w margin. I'm hoping for combination of 2 551's and 4 a2's to see the absolute max.
    - apparently the PSU could support another 295................
