    Damn - I used one of those on-line power calculators as well.
    Can you recommend one ?
    Society's to blame,
    Or possibly Atari.

    Let us know.

    Anandtech only pulled 620W for the whole system under load (crysis) with 580 in SLI, though I guess it would depend how much OCing ups things.

    I haven't seen a single one that is worth using, sadly. Just read the reviews, check what the system components are, and make an educated guess/ask on these forums.

    Re: Peoples PSU size.

    Corsair HX 850 for me as well running the below.

    E8400 at 3.6Ghz (OC'd from 3Ghz)
    4gb Memory.
    2 x 6870 (CF'd)
    1 x Raid Controller
    11 Hard Drives
    Antec 1200 Case with 7 fans

    The PSU doesn't have too many spare connectors and from the Npower Power meter we have, I think it draws around the 700W mark.

    Just hope that with my next upgrade of a Dell Perc controller, upgrade from 500gb to 1tb hard drives and new Sandy bridge processor, motherboard and 8Gb of ram is not going to push me over the 850 mark (PSU Calculators put it around the 820W mark.)

    I will I'm anticipating a hefty increase when I start OCing, since it'll be a CPU *and* two power-hungry GPUs all being clocked up (under water). I'm also going to mess with my HTPC to see if I can unlock the second core then underclock it sufficiently to get complete stability with low voltage.

    I'm such a tinkerer *sigh*

    Re: Peoples PSU size.

    400w ocz psu for my main rig.

    Got an akasa es450w in my HTPC powering:
    foxconn cinema deluxe 2 mobo
    amd 550be
    4gb ddr3 1600 ram
    1 500gb HD

    Probably overkill but its 80+ and nice and quiet. Will probs be adding in a few tbs of HD space when I move house.

    Re: Peoples PSU size.

    As per sig, but 600W Tagan powering:

    E8500
    2 sticks of RAM
    HD5870
    2x Optical drives
    3x HDDs

    I doubt I use half the capacity but then again I wouldn't wish to go anywhere near the limit either. Hoping to upgrade CPU/mobo/RAM soon, but current house move is eating all my money.

    Re: Peoples PSU size.

    the meter weve got at work doesnt do power leads, just individual cables,and its too fiddly to get it to work on PCs, so with what Zaks said and that chart kalniels posted, im revising my estimaed usage up to about 320w.

    maybe oneday - next time its in for dust removal, using the compressor - i will check this.
