factual info on how much energy my computer uses if left on 24/7?

Question

i have read that it is the largest user in a home next to your ac/heating unit

Answer 1

No home computer will draw more than half a kilowatt, and most will draw much less.

Considering most shut down at least partially whent the computer is just idling (video off, hard drive off, sections of the CPU turned off or slowed down), it's not that bad.

I would say it compares to 2 100Watt incandescents bulbs. At 10 cents a khw, that would be about $15/month.

I have an AMD box running about the same speed as a Celeron box next to it, and it seems to crank out twice as much heat. One day, I will get a power meter and stick it on these things...

Answer 2

Your desktop is probably about 200 watts and your monitor is about 100. Just maybe, the total is 300 when used, by turning off the monitor, it is less.

Here is a website with appliance wattage

Connect an electrical measuring device such as a multi meter to the power cord.

Depends if you have Intel or AMD processors. Intel uses twice the energy.

A survey was done at Macalaster College. Here are there results. They are highly efficient and surprisingly inexpensive. http://www.macalester.edu/its/faq/power_usage.html

Not at all true if you have it to go into standby (energy saver) screen mode and processor.
