The power consumption of a computer is generally how much is the monitor, the main unit

I don't know the general 7 * 100W of LCD, I recommend to read "Computer Learners - 2005 Bound Edition".

The power of the computer according to the 19-inch LCD monitor is: the maximum power is: 37W, and the standby power is: 2W

The approximate power consumption of an inch LCD computer depends on the configuration of the computer.

2.Generally, if the upper order is a monitor, it is about 40-60W, which is calculated as one hour.

3.The power of the host, depending on the configuration, generally integrates the graphics card, about 150-180W. If it's a discrete graphics card, it's about 200-300W.

4.In this way, the total (host plus monitor) is about 200-350W in an hour. It is 1 hour to 1 kilowatt-hour.

Check your computer's power:

1.Install the "Master Lu" tool on the computer that needs to check the power consumption**, then open and run, then switch to the "Hardware Detection" interface, and then click "Power Consumption Estimate" at the bottom of the left side.

2.Then Master Lu will automatically detect the computer CPU, graphics card, motherboard, hard disk, memory and other models, and will display the hardware power consumption, we just need to choose the size of the monitor we use (desktops do not need to choose the monitor), and then you can see the estimated computer power consumption at the bottom.

40w or less.

The power supply is the most critical equipment needed for the operation of the computer, the power supply itself is about 5W, and the CRT display is about 70, 80W, the power consumption of the LCD is below 40W, the power of the desktop computer speakers and other peripherals can be calculated according to 30W, combined, the power of a home desktop computer is between 230-300W.

Desktop computer good power consumption:

Generally, the power calculation of home computers is mainly: accessories in the host CPU, motherboard, hard disk, optical drive, graphics card, etc. 150W, if the LCD is 17 inches, then it is 40W, which adds up to 190W and consumes 190W per hour 1 = 190 watt-hours, which is the kilowatt-hour of electricity.

That is to say, this computer is used for 4-5 hours with 1 kWh of electricity or so, this is the maximum power consumption, in fact, not all hardware can work at the maximum power, you can calculate it according to about 80%.

Graphics card pants: Because different groups have different requirements for graphics cards, the power consumption of graphics cards is also very different, from more than 10W integrated graphics cards to more than 70W high-end mainstream graphics cards are widely used. The power of the hard disk is not very large, the maximum power of the ST hard disk is currently only about 8W for the notebook.

Motherboard: The power consumption of the motherboard itself is not very large, the power range is between 20-35W, the function consumption of the optical drive is generally about 10W, the burner is only a dozen W when writing the disk, and the power consumption of the three hardware is very low for memory, network card, sound card, because there is no specific data in Kuantong, so I don't know very much, but the sum of the three does not exceed 40W power consumption.

40w to pick up the next one.

The power supply is the most critical equipment needed for the operation of the computer, the power supply itself is about 5W, and the CRT display is about 70, 80W, the power consumption of the LCD is below 40W, the power of the desktop computer speakers and other peripherals can be calculated according to 30W, combined, the power of a home desktop computer is between 230-300W.

The power consumption of the computer host will be affected by various factors, including configuration, usage status, use of the group such as the old time, etc., here are some general computer power consumption reference:

Computer motherboard: generally between 25-40W.

Memory: When the computer is in normal use, the memory power is about 3-10W.

Hard disk: The power of ordinary mechanical hard disk is 6-8W, while the power of SSD can be lower, generally around 2-3W.

Graphics card: The power consumption of discrete graphics cards is relatively high, generally around 100W. The integrated graphics card is relatively low, generally around 10-15W.

Processor: The power consumption of different models of processors also varies, generally between 15-125W.

Combining the above factors, the power consumption of an ordinary computer is generally between 50-200W when it is used normally. However, please note that this is only an approximate reference value, and the specific power consumption will be affected by many other factors, such as model, voltage, etc., and different computers may have different collapses.

The general computer LCD monitor strategy is about 250-400W.

The power consumption of a computer per month: if it is 300W per hour, 10 hours a day, 30 days in a month = 90kW, that is, 90 kWh of electricity, this is just a conservative estimate. Display power consumption:

The power consumption of 15-inch, 17-inch, and 19-inch displays is around 60W, 80W, and 100W, respectively).

Last year, a report submitted by a Canadian university pointed out that if the latest computers have a power-saving function, they consume about 35W of power per hour of standby, which is slightly higher than a light bulb of average brightness.

The computer also consumes energy in the sleep state, which is inexplicable when it enters standby under Windows XP! It shows that the motherboard is still consuming a lot of power in order to protect the data at this time; Even if the computer is turned off, as long as the plug has not been unplugged, the computer still has energy consumption, about! Things like remote controls and smart switches make appliances easier to use, but they also add an extra energy consumption to appliances – standby energy consumption.

What is the power of a general LCD computer】It doesn't matter what the power of the LCD monitor and the computer host, they should be counted in different places.

The power of the 17-inch LCD monitor is about 30W, the power of the display is not counted in the host, and the main power (power consumption) in the main chassis: CPU + memory + motherboard + graphics card (graphics card 40W --- 300W or so) The power is different depending on the configuration.

Press the 19 inch LCD monitor computer power is:

The maximum power is: 37W

Standby power is: 2W

For details, you can refer to the power consumption description of the display.

The power of the LCD monitor is 20-40 watts, the power of the host varies from 150 to hundreds of watts, and the power of the host and monitor of the general household computer is 200-300 watts.

The current new generation of mainstream is energy-saving design, so it depends on the situation, 1, the evaluation of the mainstream configuration is generally more than 200 watts, about 5 hours of electricity.

2. The LCD display is 30-50 watts, which does not cost electricity, and it is 1 kilowatt-hour of electricity a day, and the current LED backlight display is within 20 watts.

My configuration is not the same as yours, I'm just the monitor mine is 17 flat flat, 13 hours a day, about 100 kilowatt-hours a month, if you calculate it, four hours a kilowatt-hour of electricity, your LCD will save a little bit.

First, the computer power selection of various accessories is directly related to the power supply used does not matter At present, the mainstream configuration of computer power host to 250 300w or so, 17-inch display power of about 75w, 17 LCD display about 40w If you want to save power, you can wait for the computer to turn off or hang to 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.
