How much does 2 computers cost for 15 hours a day?

If two LCDs are used for 15 hours a day, the electricity bill for a month will not exceed 80 yuan. Maybe you usually have other electrical appliances! Such as electric lights, mobile phones, flushing appliances and so on.

The normal power of a computer is more than 200W, and it will not exceed 300W, unless you have special needs!

So do the math for yourself ...

xiaojiestar is almost the same, correct solution.

kWh per hour (one computer).

2 units for 15 hours.

It's about 6 degrees.

No way! Where are you? Electricity is so cheap! It's all 1 piece on our side.

Approximately per hour.

Two units cost about 200 yuan per month.

1 computer is about 4 kWh of electricity for 15 hours. 2 LCD power consumption, one flat power consumption.

First of all, you have to figure out the meaning of 1 kilowatt hour 1 kilowatt hour is 1 kilowatt hour That is, 1 kilowatt of electrical appliances at the same time is 1 kilowatt In terms of computers, in general: CPU 50W + graphics card 20W + hard disk 15W + motherboard 20W + optical drive 15W + memory and other 20W + power supply 5W + speaker 30W + monitor 100W = 275W flat about 85W The total power consumption of your two computers is about 7 kWh of electricity for 15 hours, which is about 3 yuan and 5 cents a day.

A computer is about 350W, 1000W, an hour of electricity = 1 piece. If you use two computers together, it will be 700w-750w hours, which is yuan, and one day will be an hour = yuan, and a month will be a lot! About 300-350 yuan!

Plus the network fee, it's 350-400 yuan a month!! Very high! It's better to have a little less!

Each computer is about one degree per hour.

The computer needs about 4 kilowatt-hours of electricity to turn on for 12 hours a day; It depends on your computer's hardware configuration and the status of your computer.

Calculated based on a home desktop computer running at full load:

1. The power rating of the home desktop computer host is basically about 350W: 1 kWh = 1000W hours; 350*12 1000=degrees;

2. Monitors and speakers and other equipment: the display is calculated as 19 LCD display 70W: 70*12 1000 = degrees; Relatively small devices such as mice and keyboards consume negligible power.

Therefore, the total power consumption of the main parts of the computer is about = degree + degree = degree.

The above algorithms are all based on the results of the computer under full load operation conditions, in fact, in the process of our use, the computer will not be in full load operation most of the time, so the actual power consumption will be lower than the calculation results. 12 hours will not exceed 4 kWh.

The computer does not consume much power, but I also hope that it will not be wasted, if it is just to listen to music, it is recommended to turn off the monitor to save electricity, starting with me.

The average desktop computer has two or three hundred watts of power, and it has about two to three kilowatts of electricity for 12 hours a day.

The working power of ordinary home desktop computers is generally between 200 and 300 watts, and if you work 12 hours a day, it consumes about 3 kWh.

Hello, how many kilowatt-hours of electricity does a desktop computer need in a day? Open for about 12 hours a day,This depends on the specific situation,For example, the size of your speaker, the number of programs running,And the brightness of the screen, etc.,Generally speaking, it is a few kilowatt-hours a day。

The computer is about 300 350W when it is operating normally

3 hours of about 1 kilowatt-hour of electricity (1000w = 1 kilowatt-hour per hour) if 24 hours of power on = 8 kilowatt-hours of electricity.

A month is counted as 30 days = 8x30 = 240 degrees.

Per kilowatt-hour = yuan (RMB).

It doesn't take much.

It's about the same as a 200W light bulb.

Definitely less than air conditioning.

Have a great day.

On average, 8 kilowatt-hours of electricity are used in a day, and one month is 8 x 30 = 240 kilowatt-hours of electricity.

If the computer is left on for a full day (calculated as 24 hours), the daily power consumption:

1.The main engine power supply is 300 watts.

2.The host has 1 optical drive and 1 hard disk.

3.The display is 17-inch flat.

4.When both the hard disk and the optical drive are reading data.

The maximum current actually measured when the above conditions are met is amperes.

It can be concluded that the power of the computer is 264 watts, and its power consumption is measured in degrees for the whole day (calculated as 24 hours) when it is turned on. The minimum current actually measured to meet the above conditions is amperes. It can be concluded that the power of the computer is 176 watts, and the power consumption of the computer is in kilowatts for a full day (calculated as 24 hours).

If the computer is left on for a whole day (calculated as 24 hours), the power consumption is about between kilowatt-hours.

That's about 100 yuan.

In the same way, your computer is definitely not only a computer, but also a light-up keyboard and a mouse or audio message, all of which also require electricity. So on the whole, it is 240 kilowatt-hours of electricity a month.

Today's computers, the power supply of the main chassis is basically rated at 350W, with a peak value of 380W.

1. Power consumption of the main chassis: 350 24 1000 = degrees;

2. Display power consumption: 75 24 1000 = degrees;

3. Speaker power consumption: 65 * 24 1000 = degrees;

Overall power consumption (1 day): kWh.

Under normal circumstances, a computer is turned on and runs for 24 hours, and the electricity consumption is about three or four to seven or eight degrees, which fluctuates according to the use environment and use status.

There has been a previous article dedicated to the specific power consumption of the computer, and here we only talk about the impact of the operating state and the use environment.

The first is the state of use: normal office use, do not play large games, do not do high-power work such as design, the power consumption of the computer host and monitor will not exceed 200 watts per hour, sometimes the standby state is only a few tens of watts, and the average power consumption is about 3 degrees a day for 24 hours. Laptops and all-in-one PCs consume a little less power.

If you have been running large games or doing high-power work such as 3D rendering, and the computer is running at near full capacity, the power consumption will be higher, reaching about 400 watts, and it will be about 10 kWh in 24 hours, and the laptop and all-in-one will be slightly lower at 5-7 kWh.

Let's talk about the environmental impact: at room temperature, that is, between 10 degrees Celsius and 25 degrees Celsius, the computer runs optimally, and the power consumption will be relatively small, if the temperature reaches more than 35 degrees, it will increase the power consumption. The internal environment of the computer will also affect the power consumption, the internal dirt, too much dust, fan damage, etc. will affect the heat dissipation effect, which will also cause the power consumption to increase.

Therefore, it is necessary to try to keep the internal and external environment of the computer clean and cool to ensure that the computer runs more stably, which helps to save power and prolong the service life.

How much power does your computer consume 24 hours a day? You can estimate it yourself.
