    you have that totally backwards

    80% means that out of 550 watts drawn by the components that means AT THE WALL you are drawing probably close to 630 thats how it works because you are rectifying AC CURRENT into DC POWER and you always lose energy there in the form of heat

    you are pretty close to maxing that PSU

    If I get a reading of 500w from the wall, how much are the components actually using if the psu has 85 percent efficiency.

    if you are drawing 500 from the wall then then components should be drawing about 400WATTS if THIS IS NOT POSSIBLE WITH TWO 570'S if its reading 500WATTS Total draw AT the Wall @ LOAD then your Wattage Meter is WRONG

    either you'er pc is running on black magic or the meter is off
    I would be very interested to see what the meter reports with a different psu

    My idle to load difference at the wall is 300-400w. I think that seems right for 2 gtx 570's

    not according to the bench marks I am reading every benchmark says the GTX 570 draws any ware from 250 to 330 WATTS(just for a SINGLE CARD)

    "Our test system is based on a power hungry Core i7 965 / X58 system. This setup is overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). On average we are using roughly 50 to 100 Watts more than a standard PC due to higher CPU clock settings, water-cooling, additional cold cathode lights etc.

    We'll be calculating the GPU power consumption here, not the total PC power consumption.

    Measured power consumption

    System in IDLE = 218W
    System Wattage with GPU in FULL Stress = 578W
    Difference (GPU load) = 360W
    Add average IDLE wattage ~ 50W
    Subjective obtained GPU power consumption = ~ 410 Watts

    Mind you that the system wattage is measured from the wall socket and is for the entire PC. Below, a chart of measured Wattages per card."

    From that exact same post
    With 2-way SLI we noticed our power consumption for the cards peaked to roughly 410 Watts, that's JUST the two cards, not the entire PC !!
    so add 100Watts for the Cpu and another 50 for everything else you are pretty much MAXING IT OUT
    410+100+50 = 560WATTS http://www.techpowerup.com/forums/member.php?u=83420

    Isn't the 560 from the wall. So that is around 470w or am I getting this wrong? Is it the usage at the wall that counts or what the components actually use?

    I would Check the +12V voltage at GAMEing LOAD as draw approaches maximum the voltage will start to drop if it gets below 11.70v expect stability issues

    So my psu is fine with 500 reading at the wall (assuming that it's correct) :pimp:

    if that's correct then you have some pretty low power using 570's

    Yep but again that's total system usage (from the wall) not just the graphics card.

    also a SINGLE CARD :p
    ok ok enough with this thread anyway TL:DR you need a 650 or better PSU better be safe then on fire I always say ..

    :) I have already ordered a 750w just to be extra safe!

    ps: 1 more post for 1337
