    I wanted to find out how much it costs me to run the machines and how much electricity each one uses. I used a Kill-a-watt for this purpose.

    Here are the results:

    Cost of kWH in Florida
    Count.................From Fuel...............Non-Fuel.............Total
    <= 1000kW........$0.03950................$0.04748............$0.08698
    > 1000kW..........$0.04950................$0.05748............$0.10698

    For this test I assume my consumption falls within the first 1000kWH and I am using the average cost per kW.

    kW x 30 days...66.5568.........105.5952.........127.404

    Cost................Idle...............CPU...............CPU+GPU
    kWH...............$0.00804.......$0.01276........$0.01539
    kW x 1 day......$0.19............$0.31.............$0.37
    kW x 30 days...$5.79............$9.18.............$11.08
    PPD/$ 1 day........................

    Hopefully I did it right! I thought this might be interesting!

    Second Edit: I'm surprised the cost of running the GPU is not more....hmmm.
    Third Edit: Corrected cost per kWH.

    Well, it would be very interesting to calculate the cost as in ppd/$, i.e. take your ppd for each computer and divide it by the dollar amount for one day - or for a week or a year ...

    I think you're supposed to add the fuel and non-fuel costs. Here in CO, the total is ~12 cents/kWH. Less than 10 is rare, from what I hear.

    In Florida, also consider the cost of A/C to pump that amount of heat out. Unless you have a ground-source heat pump (Peter, want to weigh in on that?), that's likely to be at least 70&#37; of the direct electricity consumption, and could easily be more than 100% of it.

    I will look at my power bill and make sure. I will update later.

    Peter - ppd == points per day?

    You were right. I've corrected the cost per kWH. Thanks for pointing out!

    @wayliff: Yes.

    @Ken_g6: A ground source heat pump does not work very well in cooling - I get less than 30% efficiency when cooling, more than 85% when heating ...

    ok it's been added...

    edit: I removed the values as I'm trying to figure out how to add my machines to boincstats.

    I recently borrowed some KAW meters, and hooked them up to my desktop rig.

    Q9300 @ 3.0, stock voltage, GTX460 1GB (715Mhz stock OC), and a KDS 26" LCD.

    LCD: 59-63W
    Idle at desktop: 96W
    F@H GPU: 194W
    OCCT PSU test: 353W (CPU overheated > 85C! GPU temp was like 83-84C)

    I pay $0.15 per KWh.

    I get 10K PPD in F@H on the GPU.
