Add in cooling costs and you can start to see where the > money goes.. watt hours != amps If you get 80A @ 120V, your equation would be (ignoring power factor): $.10 * 120V * 80A / 1000 * 24 hr * 30 day = $691 A good rule-of-thumb for cooling "overhead" is around 60%, so that would add another $415 for a total of $1106. I don't know where you are, but 10 cents per kWh seems kind of high for commercial electric rates. -- Chris Adams <[email protected]> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. -- Eat sushi frequently. - Avi [email protected] is the human contact address.
