Subject: How can I calculate what my computer costs me?
How can I calculate what my computer is costing me? I don't mean the parts; I mean what it is costing me in electricity to run an ftp server, or to run a gaming server.
I'm not really concerned about the cost; I just would like to know how to calculate it.
Example System: 2200XP+, 1GB DDR333, 80GB HDD, nVidia Ti500, 2 Case Fans, 430W PSU, NIC, Sound Card, USB Card, Firewire Card, Floppy, DVD drive, CDRW drive
Cost per kilowatt: $1.50 (not sure what it is, just as an example)
I think someone said it best this way.

I'd say about $10-$15/Mth (Say $7.50-$12.00 US) depending on your electricity costs.
I'd be more worried about the depreciation on the value of your computer.
The UPS and perhaps fire hazard.
Internet badwidth if you have limits are are likely to exceed them.

Here's an easy way. Certain online Appliance stores sell power totalizers. You plug your electrical device into it, then you plug that into the wall. It will record and display how much power you use over a certain period of time. They are pretty handy, but expensive.
Another way to do it is measure the current draw your computer uses with a multimeter and multiply that by 110. That will give you power in watts.
Two ways. TThere are inductive current clamps. It's spring loaded clamp that you place around one leg of the power cord going into the power supply. It really measures the intensity of the magnetic field generated by current passing through the conductor...so its an indirect measurement, but accepted as faily accurate. Also you can "jumper" one leg of AC cord with the multimeter leads, but you have to have a good meter that can handle that much current (although its probably around 1 to 2 amps). I wouldn't recommend either way. The first one is expensive, and the second is dangerous. If you are really interested in doing this use the power totalizer I talked about.
90-110 watts? Sounds awful low. If PCs could get by on this low of a power draw we wouldn't need 300-400 watt power supplies.
Your overclocked Barton is drawing at least 70 watts all on it's own. Your monitor has got be using 60-100 watts (unless you have an LCD panel). Video card 10 to 50 watts. Fans 10-20 watts. Well I think you get the picture.
