    Default power meter for PC

    Dick Smiths have an Elto mains power meter for $25.
    http://www.dse.co.nz/dse.shop/4b8b4f...uct/View/M7319
    Anyone know if this will accurately report PC power consumption? I'm running Folding at Home clients (SMP and GPU2) and want to know how much it's going to cost me to run 24/7.

    All I can tell you is Elto powerboards are utter rubbish.

    I wouldnt bother with FAH either. It can slow a system down. Theres some reviews there. Click on reviews. It not that good

    Of course it's going to slow the system down, it will be trying to use maximum CPU time... (which is the point of it)
    Non-system disk or disk error. Replace and strike any key when ready.

    From the Specifications tab on the DSE product page:
    Measures an appliances power usage
    Displays Voltage
    Displays Current
    Displays Power & Power Used
    Displays Cost
    Sounds like what you want, yes?

    F@H only uses idle cycles at lowest priority so scales back when any load is detected. In my observations I have not seen any slow down on the cpu side and only minor slowing on the gpu. Either client can be turned off at any time anyway, so if you're going to do something intensive you just switch it off.

    I find the science behind it intriguing. The fact that the combined processing power is over 4x that of the world's fastest supercomputer (Cray XT5) is also quite remarkable, with power consumption being more or less on the same scale, I believe.

    The Elto might be the best available at that price, will see if I can find any alternatives.

    Yer I know what the point of it is. IMO its a waste of space and time

    Looks like it would work (why wouldn't it!).

    One of the reviews states they used it on a laptop. Also it can measure usage over the month and tell you how much it costs

    (always wanted one)

    Pretty cheap too, tempted to get one (or three) for here

    Despite a wide ranging search, I couldn't find out about the accuracy of this device, and it was asked ..."if this will accurately report PC power consumption?"
    The so-called "specifications" on the DSE site are next to useless, no accuracy, resolution or ranges quoted.

    Neither could I find specifically whether it measured power factor, though there were suggestions that it did.

    There were reports that it wasn't all that good for measuring "low powers", but not much indication of what was meant by "low", but I take it to mean power level commensurate with the last digit readout, whatever that is, 1 watt or more.

    Since it has a NZ plug and socket, it will be rated at 10 amps at least, I read 16 amps for a similar meter having NZ plug adapters, so it would probably have to read up to at least 230v x 10 amps = 2300 watts.

    If it is a 3 digit display, the smallest power reading may be 10 watts, which is a bit high.

    This is all guesswork

    Better to read the accompanying leaflet before buying.
