    That unit is using 289w AC according the current transducer.....so I am going to go with the current transducer being correct


    Figure between 45-65W range.

    Either way, it makes sense.


    18W for the HDD's at idle
    5W for the E4500 at idle
    5W for the 78nm D9HNL micron ram at idle
    8W for system board at idle
    5W for USB/Firewire/lan etc at idle

    Maybe, I just wouldn't put full faith and credit into is all. I only noticed something was funky with the Kill-A-Watt's not working right with ~25%-30% of power supplies because I know my exact DC loads....not estimates. That is why you see that second box in the picture that I used to run in series with the attached current transducer. The Kill-A-Watt would be off but the Brand+Extech would be correct on those same units. I don't have an earth watts to know if it is a problem unit but I am just warning you not to take the Kill-A-Watt for anything more than a guesstimate without knowing DC loads.

    Have you tested the Etech PM-300 power meter?
    Looks like so:

    No I haven't. I'll have to see if they are available in the US. The one I am using now hasn't had the same issues so I wasn't really looking for new ones but if tis available I may get it and play with it.

    Ok, I'd send you one but it's rated for only 230v 50hz

    And you don't have a power converter right?
    I've seen this design for 110v also though, can't remember the name however (saw it on this forum)

    Was playing with another one today and figured I'd hook up the Kill-A-Watt again...and sure enough boom:

    Spectre, do you have a 110v 60hz to 230v 50hz power converter?
    If so I can send you one of those power meters... If not I'll try to find a US version of it...

    Can I see a shot of the Brand Electronics meter reading the wattage with the Brand Electronics connected to the wall, then the Kill-A-Watt into Brand and power supply into Kill-A-Watt?

    Can you also shown a simplified diagram of how your setup is all hooked up? I see a power conditioner, then a variac(that's obviously feeding the KAW).
