How much power does a computer have How powerful is a computer in general

An ordinary computer can be used for 5 hours a kilowatt-hour, which is equivalent to a power of 200W, but now the LCD monitor has 200W, and it is estimated that the current computer has between 300W-400W.

<> First, the computer power selection of various accessories is directly related to the use of the sail forest source does not matter At present, the mainstream configuration of computer power host to about 250 300w, 17-inch display power of about 75w, 17 LCD display about 40w, want to be chaotic acres of power saving, can be used to wait for the computer to turn off or accompany the suspect to hang sleep.

Second, the current mainstream is energy-saving design, the LCD is 30-50 watts, about 40 watts, not counting electricity, a day is 1 kilowatt-hour of electricity.

Today's LED backlit displays are within 20 watts.

The power of a typical desktop computer ranges from 180W to 500W.

The training power of the computer is mainly determined by the power consumption of several components, first of all, the performance of the CPU, GPU and other components inside the host is different, and the rated power and peak power of the operation are different; The power consumption of peripherals such as keyboard displays is low, generally about 15-30W; Generally speaking, the power supply of the home host is about 500W, and the orange cover can meet the rated use and leave a certain peak use needs.

Generally, the rated power supply of the core display office computer host is about 300W, if you need a discrete graphics card rated at about 400W, a 4-core or 6-core mid-range Wukong host with independent display, rated 400W power supply, if it is a mid-to-high-end six-core independent display host, it is recommended to be about 500W, and the higher-end game console or the host that needs to be overclocked needs a higher power supply.

The main features of the computer are as follows:

1. The operation speed is fast

The computer is composed of internal circuits, which can complete various arithmetic operations at high speed and accurately. Today's computer systems have a computing speed of trillions per second, and microcomputers can reach more than 100 million times per second, enabling a large number of complex scientific computing problems to be solved.

2. High calculation accuracy

The development of science and technology, especially cutting-edge science and technology, requires highly accurate calculations. The accuracy of a computer-controlled missile against a predetermined target is inseparable from the computer's precise calculations. Generally, computers can have more than a dozen or even dozens of significant digits, and the calculation accuracy can range from a few thousandths to a few millionths, which is beyond the reach of any calculation tool.

3. Strong logical operation ability

Computers are not only capable of accurate calculations, but also have the function of logical operations, which can compare and judge information. The computer can save the data, programs, intermediate and final results of the calculations, and can automatically execute the next instruction according to the judgment results for the user to call at any time.
