    Is there a simple way to know how much power a device is taking. Let's say
    for example: a CRT monitor. By the specs, it seems that my 21" is taking
    about 150W. But, when it goes to sleep, I wonder how much it take. I know
    it's going to be a lot lower but I'd like to mesure it without having to
    contact them and ask them. I'd like to do this for my workstations too.

    Is there something existing that I can buy that could help or something not
    too fancy (hey, I'm a newbee here) that I could build.

    Thanks !

    What you're looking for is called an 'AC power meter' and if you search
    Google you'll get a zillion hits. If you don't need something long-term
    you could rent one, take your readings and then return it. You can also
    find rental units on Google.

    If you want to build something instead of buying or renting, and you
    want to measure watts instead of Volt Amperes it can get a little
    complicated, but I'll be glad to help you (as I'm sure others here
    would) if you're serious and that's what you want to do.
