    Ive got a few machines at home and im wondering which one would be best left on 24/7 to use as a torrent machine/media server.

    Machine #1
    Dell GX270 SFF PC
    P4 3.0Ghz (Prescott) with 1Gb ram and onboard video (865G chipset).
    160Gb Hdd
    160w PSU

    (As there is not enough room on this PC, ill also be connecting an external 400Gb 3.5" hdd to it).
    I could put the 400Gb instead the PC, however i figured it would be handy to have it as an external incase i needed to take it somewhere).

    Machine #2
    E8300 + Gigabyte EP31-DS3L + 2Gb Ram + 7600GT
    WD 500Gb (AAKS) hdd + Seagate 320Gb hdd
    Enermax noisetaker 430w PSU.

    I would guess the Dell, easily.

    I would have the E8300 consumes less easily...

    The Presshots consumes lots of power ++++ 95nm process.
    the E8300 is a 45nm process..

    but offest by the 7600GT in the E8300...and thee xtra hard disk..

    I could be very close.. however.. I still would have though the E8300, probably consumes less...

    processors from one generation to the next dont really consume and more or less power.
    intel has the whole 1:1 power increase to performance gain policy
    each die shrink reduces power in a generation. each generation increases power+performance
    die shrink reduces power.
    etc.

    7600GT would be the biggest difference
    so Dell. definitely.

    But definitely a PSU with an output of 160w (Dell) should consume less electricity than a Pc running on a 430w PSU (E8300 PC) right?

    That said, everything seems to be pointing to the dell already.

    There will be efficiency curves for each PSU so I wouldn't make that conclusion just yet. Probably eaiest just to put both on a meter and find out for sure. Make sure all the power saving features of the Gigabyte EP mobo and 8300 CPU are on, but even if they are the videocard is probably going to use up a fair bit just by itself.

    I would say the Dell would pull about 180w. the other would pull about 200-220w, pretty negligible difference between the two.

    You know what i meant. :tongue:

    A 430w PSU won't pull 430w unless it's 100% loaded. The Dell may have a 160w PSU in it, but it's probably loaded to 80-100% (bad). Whereas the E8300 machine may have a 430w PSU in it, but it's only loaded to 40%.

    PSUs are most efficient when running at about 80%

    40% load on the 430w would most likely alot of power to the overall consumption

    Sure, but you're talking about maybe a 5% variance in efficiency... at <200w.... it's not going to equate to anything measureable.

    You're also assuming the psu in the Dell is of a decent quality....

    well im guessing the 430w is a thermaltake so not that great either

    Its an Enermax Noisetaker 430w. Not some crappy thermaltake.

    well you dodged a bullet there

    not so bad then, still recon a 160w psu can only be so inefficient
