    Hey,
    How can i find out how much power my PC and monitor are using - i want to work out the current theyre drawing. Its a HP Vectra VL800 with HP P720 17" monitor. I can work out the power for my tv, hifi etc. cos i have the manuals for those but i havent anything that shows the power consumption for my PC..

    The power supply will have its rating labeled, probably visible only when you open the PC case. The monitor should also have a rating labeled on the back - either in watts or amps. Both of those will be maximum ratings, not actual, but the same is probably true of anything you'll get from a TV manual.

    If you're feeling brave, really really brave, you could use a multimeter in series with the live wire to measure the current directly. Most multimeters are good to 10 amps or so, more than enough. Be aware that more than one Darwin Awards entry has used mains electricity.

    I wont do the maths for you, because I am tired, but at a recent Darkside LAN, we had 30 pc's complete with monitors running for 24 hours - and we only used 5 KWh

    When you work it out, you will see that it is probably less than you thought.

    Hope this is some help

    Each PC is different and thus you have to determine how much power each component consumes. Maybe this article would clear things up:
