can someone please sanity check this cheers

volts x amps= watts

235v x 0.85amp = 199.75

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

That calculator is assuming there are 240 days in a year - I guess it only counts business days and assumes equipment is turned off on weekends and holidays. If it assumed 365 days a year, total kW would be 1749.8, not 1150.5.

Also, your 258.84 figure is an annual dollar cost, not a total kW use in a year.

but does it cost 250 or 1000 to run an entry level server per year always on?

Callandor

For 365 days/year, that's 1749.8 * $0.15 cost per kW = $262.47 - I don't know why the calculator is using a $1.00/kWhr rate.

how can u see it using 1 dollar an hour? its default is 0.11 euro cents?

so a milloin percent if the watt draw is 128watt on my meter its roughly 250 euro for 365 x 24 x 7

Please confirm thanks for your help
