    It varies widely, but roughly 65 to 250 watts. The source has a chart with more details.

    Probably a similar amount as 1-2 incandescent lightbults, so 60-160 watts. Average is very hard to measure, considering the huge variety of computers. This statistic is totally ignoring laptops, or other small computing devices which aren't PCs (which are MUCH lower power), as well as monitor's consumption, which depends on size, and CRT/LCD. It's much easier to find monitor consumptions though, both idle and active.
