Desktop computer electricity usage

What is electricity consumption of average/common desktop computer?

On average, a desktop computer uses between 60 and 300 Watts. Because there are so many various hardware combinations, it is exceedingly challenging to determine exactly how much computing power computers utilize on average. Because the power supply output is listed as the maximum amount of watts a power supply can output, using the computer power supply as a gauge for energy use is inaccurate. A computer's power consumption is also greatly influenced by its video card; a powerful video card may consume a lot of energy, and using several cards (in SLI or Crossfire mode) while rendering or playing 3D games can consume a lot of power. Without the LCD screen, we predict that a typical current desktop PC will consume about 100 watts of electricity.

Kilowatts per dayhelp Here you will see a value for how much energy (in watts, kilowatts or megawatts) the device will consume per day if it is used for the time you specify. The formula "Hours used per day" × "Power use" is used.:

Watts Kilowatts Megawatts

Hours Used Per Day: Indicate the average number of hours per day that the device is used. If the daily power usage is less than one hour, enter the number as a decimal (for instance, 30 minutes a day equals 0.5).

Power Use (Watts): Type in the watts that represent the device's typical power use.

Price (kWh): Enter the price per kilowatt hour you pay typically; our calculators use a default value of 0.10 (10 cents). Check your power bill for the precise cost.

When not in use, turn off your computer and activate power-saving options like hibernation, standby, or sleep mode. You can rapidly switch on a computer when you need to utilize it by using power-saving modes. Sleep mode can be programmed to activate automatically after a predetermined amount of inactivity and normally consumes just 1 to 5 watts of power.

We advise purchasing a power meter or electricity use monitor, which is placed between your power outlet and any plugged-in gadgets if you want to determine the precise amount of electricity your desktop computer is using. This will enable you to precisely determine how much energy your computer is consuming.
