Interactive power consumption calculator – calculate current consumption and energy costs

Interactive electricity costs calculator – calculate power consumption
Calculate the current consumption and cost of electricity …
With this simple online tool one can calculate fast and easy the current consumption and electricity costs. No matter, if one would like to calculate the computer power consumption or other household equipment. Simply change the values in the lower range and watch the approximate costs for your inputs. The interactive power consumption calculator and the examples are an excerpt from our last power supply review and compares a standard 80PLUS power supply with an 80PLUS Gold power supply.

Examples PC Power Supply Unit 1 PC Power Supply Unit 2
Consumption in Watt 140W 116W
Consumption per year
with a daily use of 1 hour
365 days x 1 hrs. x 140W
= approx. 51 kW
365 days x 1 hrs. x 116W
= approx. 42 kW
Costs per year
with a daily use of 1 hour
51 kW x * 0,22 EUR
= approx. 11,22 EUR
42 kW x * 0,22 EUR
= approx. 9,24 EUR
Costs per year with
a daily use of 8 hours
at 230 days per year
e.g. office PC
230 days x 8 hrs. x 140W * 0,22 EUR / 1000 = approx. 56,67 EUR per year 230 days x 8 hrs. x 116W * 0,22 EUR / 1000 = approx. 46,96 EUR per year
Costs per year with
a daily use of 24 hours
at 365 days per year
e.g. server
365 days x 24 hrs. x 140W * 0,22 EUR / 1000 = approx. 269,80 EUR per year 365 days x 24 hrs. x 116W * 0,22 EUR / 1000 = approx. 223,56 EUR per year

days x hours x Watt * Cent kWh = approx. EUR
Optional comparison PSU with Watt = difference of approx. EUR
