How many watts does the average computer use while idle?
- ElmyrLv 71 decade agoFavorite Answer
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.

Monitor; LCD 25W, CRT about 75 Watts
Computer acive; 60-250 Watts
Computer, inactive, not in 'sleep' mode; 60-250 Watts
Sleep mode: 3-10 watts

you can get a kill-a-watt to check it yourself.
