Electricity consumption is one of the most important parameters that you should pay attention to when choosing and buying a personal computer. It depends on the power of the computer and the load on it.
The consumption of electricity by the user's personal computer is directly related to the power of the components that make up the PC itself, as well as to the degree of its load with various software. Thus, it turns out that, for example, if you buy a powerful power supply unit, then it will consume much more electricity. It is worth remembering that the more processes are running on the computer, the more the power supply will be consumed, respectively, and much more electricity will be consumed. The purpose of the running processes is very important, that is, if you just work in a browser, then electricity will be consumed much less, and if you play games or work with demanding graphic applications, then more. As a result, it turns out that all these three factors (power supply unit capacity, number and complexity of processes) directly affect energy consumption.
Computer power consumption
A typical office system unit running office applications typically consumes between 250 and 350 watts per hour. A more powerful computer that runs graphics applications and games will accordingly consume more electricity, on average 450 watts per hour. Do not forget about information input-output devices that also consume electricity. Modern monitors today consume 60 to 100 watts / hour. As for printers and other peripheral devices, they consume about 10% of the electricity, that is, it turns out that they use about 16-17 watts.
average cost
If we calculate the average cost of electricity consumed by a personal computer per month, then it is enough to multiply its cost by 30 days. For example, if we take the maximum cost of one kilowatt-hour at Moscow rates, then it turns out about 3.80 rubles. Thus, it turns out that if you use a standard office computer at the limit of its capabilities throughout the whole month and with an electricity consumption of 250-350 watts / hour, it will cost 950-1330 rubles per month (if you work at the computer for more than 8 hours daily, every month) … A gaming computer, accordingly, will consume much more electricity, therefore, more money will be spent on using such a device. Of course, the final amount of electricity consumed depends on how long the computer will be used and under what conditions.
