How much power does the computer have, and how powerful does the computer have?

It is the heart of the computer and the main energy consumer of the computer. Now Intel's P4 mainstream CPU is the most powerful.

100w or so. The CPU we use is mostly waiting for tasks and rarely running at full capacity (the CPU usage can be seen in the task management of WindoS2000, and the general usage is about 50%), so in general, the CPU is about to work at less than 50W.

2.Graphics card: The graphics card is the graphics processing center of the computer, because different groups have different requirements for the graphics card, so the power consumption of the graphics card is also very different, from the integrated graphics card of more than ten watts to the high-end mainstream graphics card of more than seventy watts are widely used.

But even if the same model of graphics card is used in a different environment, there is a huge difference in its power.

3.Hard disk, the power of the hard disk is not large, the maximum power of the current ST hard disk is, the notebook is only about 8W. And we don't write and read data from the hard disk frequently, so usually the hard disk works most of the time under no load, and the power is only about 15W.

4.The motherboard, the power consumption of the motherboard itself is not large, and the power is 20W.

5.Optical drive: The power consumption of optical drive is generally about 10W, considering the future development, take 15W.

6.The power consumption of memory, network card, and sound card is very low, due to the lack of specific data, but the total power consumption of the three will not exceed 20W, calculated as 40W.

7.Power supply. The power supply is the most critical piece of equipment needed to run a computer, and the power supply itself is estimated to have a loss of 5 watts.

8.Display: The display can be calculated as 100W, but with the future development, the LCD will become more and more popular, and the power consumption of the LCD is very low, below 50W.

In addition, the power of peripherals such as computer speakers can be calculated at 30W.

Based on the above calculations, the power of a computer (including the monitor) is roughly around 350W.

Nowadays, the power of the average computer is 300-350W

Computer power can be divided into two types according to the type of computer:

1. The general power of desktop computers is about 230 watts to 300 watts;

2. The power of the laptop is around 40 to 50 watts.

The details are as follows: 1. CPU is the main energy consumption of computers. In general, the CPU does not work more than 5 watts normally. The rated power of the dual-core CPU is generally around 65 watts;

2. The graphics card is the graphics processing center of the computer, and the energy consumption of the graphics card is constantly changing according to its model and use environment;

3. The power of the hard disk is not large, the maximum power of the current ST hard disk is watts, and the notebook's is only about 8 watts. Usually, the hard disk works under no load for most of the time, and the power is only about 15 watts;

4. The power consumption of the motherboard itself is not large, and the power range is between 20 and 35 watts;

5. The power consumption of the optical drive is generally about 10 watts, and the power of the recorder is also tens of watts when writing disks;

6. The power consumption of the three hardware, memory, network card, and sound card is very low, and the total power consumption of the three will not exceed 40 watts;

7. The power supply is the most critical equipment required for the operation of the computer, and its own loss is estimated to be 5 watts;

8. The CRT display is about watts, and the power consumption of the LCD is less than 40 watts.
