Let's do the math for me personally carefully,

http://forums.pcper.com/showthread.php?t=467031 my main system draws 332 watts when folding.

With my second system folding as well, I draw 462 watts. I have a two other systems built similarly to the second system that I use to fold, or did, 462-332 = 130 per system * 3 = 390Ws for all the athlon 64s

My power supplies are both 80+ rated but are aged. 80% efficiency is a good guess. This means 20% of either 332 or 462 watts are dissipated as heat, not counting the system internals. My best guess is another 10% of the power burnt would be dissipated as heat, but that's a shot in the dark and also a convenient number to estimate to considering..

My electricity costs 15 cents per kilowatt hour as of 2008.

so 1000W is 15 cents

1000/1000Wis 15/1000 cents = .015 cents per watt/hour

The wattages:

332 watts + ( 332*.10 ) = 365.2

390 + ( 390*.10 ) = 429

The costs:

.015 cents per watt/hour * 24 hours * 30 days = 10.8 cents/mo to burn a single watt.

(365.2 * 10.8 )watts * cents/month /100 cents= 39.44 dollars a month to run my main system only. So my 40 dollar/month guesstimate was right on the money ( I'm proud of that, actually ) Times 12 it's costing me 480 dollars a year to run this.

To add the secondary systems in, ( 429*10.8)/100 = 46.33 dollars/month to run my secondary systems. This costs me 552 a year.

In essence, to run all of my computers, it would cost me 86 dollars a month. This would put me on a much bigger TV than I first guessed.

Now PLEASE point out a flaw in my math, because it looks like two people have came into this thread telling me I should want to give 1000 a year to be in a community telling me I'm a bad person for wanting to see something out of my money.

And before anyone asks, I've started using more aggressive power saving settings on these systems and even have them going into standby now. They're also shut off at night.
