How powerful is the desktop computer?

An ordinary personal computer consumes about 130 watts to 250 watts, but few people know that even if it is turned off, the computer still consumes power as long as it is not unplugged.

Take the configuration of an ordinary "Benz" computer as an example, the power consumption of its host computer is about100W when it works normally. Adding a 17 inch CRT display will increase the power consumption by about 60 watts. If it is a 17 inch LCD screen, the power consumption can be reduced to about 30 watts. If equipped with a pair of speakers, the power is about 25 watts.

Generally speaking, when a computer works normally for one hour, the power consumption is about 130 watts to 250 watts (the specific value cannot be counted because it is greatly affected by the configuration). Although its power is not the highest among all household appliances, in fact, because the computer has been used for a long time, the comprehensive power consumption is also very large.

It consumes a lot of power to turn it off.

Anyone who has used a computer should know how to turn it off. But few people know that computers are consuming power even when they are turned off.

The computer has adopted a technology that enables the host computer to provide a DC current of 5V,1000 mA when the power is cut off, so that a few circuits in the computer can keep working. A computer, just like a TV set, can realize functions such as remote startup, software shutdown and timing shutdown.

However, it is this kind of well-meaning technology that causes the loss of electric energy. If the plug is not unplugged after the computer is turned off, a computer host consumes 5 watts, a monitor 5 watts, a speaker 10 watts, and a kitten (modem) 3 watts, excluding printers, scanners and other less commonly used equipment, adding up to 23 watts. Stand by and watch for at least 10 hour every night, so that after one month, the 7-degree electricity will be lost unconsciously.
