The power consumption PC is directly connected with the power components included in the PC, as well as the degree of congestion of different software. Thus it turns out that, for example, if you buy a powerful power supply, it will consume much more electricity. It is worth remembering that the more processes will be running on the computer, the more will be consumed in the power supply, respectively, and electricity will be consumed much more. Much more importance is the purpose of running processes, that is, if you just work in the browser, the electricity will be consumed much less, and if you play games or work with demanding graphics applications, then more. The result is that all three of these factors (power supply, number and complexity of processes) directly affect the energy consumption.

Electricity consumption by the computer

Standard office system unit with operating office applications mainly consumes from 250 to 350 watts per hour. A more powerful computer that is running graphics applications and games, respectively, will consume more electricity, for an average of 450 watts per hour. Do not forget about the input devices and output information, which also consume electricity. Modern monitors today use 60 to 100 watt/hour. As for printers and other peripherals, they consume about 10% of the electricity, so they use about 16-17 watt.

The average cost

If you expect the average cost of electricity consumed by personal computer per month, it is enough to multiply the cost for 30 days. For example, if we take the maximum cost of one kilowatt-hour at the Moscow rates, it turns out, about of 3.80 rubles. Thus it appears that if you use a standard office computer to the limit for the entire month and the consumption of electricity from 250-350 watt/hour cost per month 950-1330 rubles (if to use the computer more than 8 hours daily, every month). Gaming computer, respectively, will consume much more electricity, therefore, and money to use such a device to spend more. Of course, the final quantity of electricity consumed depends on how much time you will use the computer and under what conditions.
