# How much does my server cost to run?

Posted on 2009-07-15

Hi

I have a HP ML 350 G5

I have an energy monitor on the server and i am trying to work out the energy costs per month, far below is what i worked out the cost to be using the energy monitor does this look about right really looking for a sanity check

Also the energy monitor reads 10.85kwh if thats the case is it not

10.85 x 0.15c = ¬1.6275 per hour (this cant be correct is it?)

as using the above works out at mad money are my below calculations correct or this one?

confused???? please help

HP ML 350 G5 (No Monitor connected)

volts x amps= watts

235v x 0.85amp = 199.75w

Airtricity ¬0.15c per KWh

24 Hours Per Day X 30 Days per Month (average) = 720 hours per month

199.75 Watts Per Hour X 720 hours per month = 143,820 Watts per month

143,820 Watts per month / 1000 Watts per Kilowatt hour = 143.82 kW Hours

143.82 kWh X .15 cents per kWh = ¬21.57 per month

¬258.84 per year

¬21.57 / 720 hours = .0299 euros per hour/ 2.99 cents per hour
