Does a computer cost electricity? Does your computer drain power?

Computers don't really have a lot of power.

24 hours a day, that is, 3 to 4 kilowatt-hours of electricity, but often turning on and off the machine will consume more electricity and damage the machine.

The general power of the computer is between 300-350W, the monitor is about 35-50W, the speaker is usually not very loud, generally 2-3W, a total of about 350W-400W, 1000 350 = hours.

1000 400 = hours.

This is about 2 hours to 2 hours and 50 minutes of electricity.

It consumes about 8 degrees of power in 24 hours.

The power consumption of a computer is not too high in a home appliance.

Because the computer is dynamic power, the total power is not certain and has a certain fluctuation.

I'm an electrician.

In general, the power consumption of a TV is less than 80W, and the power consumption of a computer 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.

Computers also consume energy while asleep, about, puzzling in Windows

The power consumption of XP when entering standby is reached! 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.

Some people calculate that the power consumption of the computer is between 250W and 400W, and some people calculate it according to 300W. In fact, by counting the number of revolutions of your home's electricity meter, you can calculate the power consumption of your computer. I once observed the meter:

Turn off all the electrical appliances in the house, only turn on the computer, and my meter turns 6 times in 10 seconds, so one minute (multiplied by 6) turns 36 times, and one hour (multiplied by 60) turns 2160 times. Divide 2160 by the number of turns per kilowatt-hour indicated on the meter (my meter indicates "each kilowatt-hour is equal to 7200 laps", that is, 2160 divided by 7200), and the number is. That is, my computer consumes electricity per hour (or 300 watts of electricity per hour).

In this way, my home computer consumes 12 hours of electricity). If you don't need to be so accurate, you can estimate according to the range that everyone says, and if you want to be precise, you might as well try it.

Now the mainstream desktop computer on the market, the energy consumption of normal use under the Windows XP system is 250W 400W, the energy consumption in the dormant state is about, and the energy consumption when entering standby is about, even if the machine is turned off, as long as the plug is not pulled, the computer still has energy consumption, about!

How much does a home computer like this consume in a month? If it is 300W per hour and you use it for 5 hours a day, then the power consumption in a month is 45kW, which is 45 kWh.

In fact, the power consumption of a desktop computer for an hour is not small! Generally, the TV is below 80W, but the computer is different, and now the power consumption of a computer is between 250W ---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, calculated according to each kWh, it is RMB 45. This is only a conservative estimate.

As long as the computer is on, it consumes electricity, and it has little to do with what you play.

The minimum power of the general power supply is 300W, and 10 hours is 3kWh, which is 3 kWh, just look at the power of your power supply, and the power of the LCD display is almost negligible, all within 10W.

The power consumption of the machine is different in different working states, so the average power is more objective.

The average host is 150W

The average of 17-inch LCD is 35W

The 17-inch CRT averages 85W

The average sound is 15W

In addition, the standby state also consumes about 30W.

The average electricity of liquid crystal is 1 kWh in 5 hours, and the average electricity of CRT is 1 kWh in 4 hours.

Basically, today's computers consume between 240-280W.

Of course, it depends on what kind of computer you use.

And what are you doing with the computer?

Playing big games is definitely a battery drain.

And there is. crt

The display consumes a lot of power.

It's about 80w.

Liquid crystal. Just a dozen watts.

Whether it costs electricity or not, you see how to compare, and what to compare, the difference in power consumption between different computer configurations is very large. However, most of the popular computers consume power at 250-400W (this includes the monitor), and in fact, the power of the computer is not fixed, for example, if you play games, it will definitely cost more power than when you read txt documents. So it's hard to say exactly.

Subwoofer, which consumes more power than headphones? This is the case that subwoofers can range from tens of watts to hundreds of watts, while headphones are only calculated with howls. So definitely these two consume more power than subwoofers, I personally think that if you buy a subwoofer, it is better to spend this money directly on headphones to buy a good headphone, the effect is definitely much stronger than the subwoofer.

It is true that computers cost more electricity than ordinary household appliances.

It's like a TV, an electric light, it doesn't cost.

The computer is worse than the rice cooker, the computer needs to use about 1 kilowatt-hour of electricity a day, the power of a computer is about 200W, and it takes about one kilowatt-hour to turn on for five hours.

It has not been compared with what kind of household appliances, generally and the power is about 300W, and the composition of computer power is as follows:

1, CPUP2 more than 30 watts.

P3 Max about 60W.

P4 max 84W (max 95W for overclocking in gamers' hands, and the usage rate is extremely high).

2. Graphics card. The integrated ones are around 15W, while individual graphics cards from a dozen watts to more than seventy watts have been widely used.

3. Display.

17"CRT (in the case of Mitsubishi underneath) is 96W, while the LCD will be below 50W.

4. Hard disk. At present, the maximum power of ST's hard disk is only 5W

5. Network card, sound card, memory.

I haven't found exact data yet, and it's not too much to estimate 15w.

6. Optical drive. Generally around 10w.

7. The power supply and the motherboard itself also have energy consumption.

Estimated 15w8, speaker.

Take the example of the bass bubble that is commonly used.

The power is around 30W.

The above is the sum of the higher values p w

Just look at the power of your power supply. Generally, it is 220W, and the kWh is 1000W

If you use a 220W power supply, you will only use 1 kWh for 4 to 5 hours.

Of course, it costs electricity, of course, to avoid this phenomenon, you can change to a drive with less energy consumption, or you can turn off the power of accessories connected to the computer when you are not playing with the computer, such as the monitor is always in standby mode. If you are troublesome, buy a voltage regulator, so that you can also save a lot of electricity every month.

An hour is one kilowatt-hour of electricity!

You unplug the cable of the optical drive.

That's it. Actually, computer's.

The power is rated.

It's not going to change. You play cf

It's that power too.

It doesn't matter what you run.

In general, the computer power supply is more than 300-400W, and the power supply is calculated according to the 300W power supply, which can be calculated according to the power of the power supply.

LCD display is generally 50w-60w

The power of the 4-core chassis is 350W-450W

Since it's 4 cores, your card's power consumption is at least 100W or higher.

If you leave it on for 24 hours, it may take 8-9 kilowatt-hours of electricity.

Of course, the computer consumes electricity, and every part of it consumes electricity... You can remove some parts that you don't normally need, so you can save some electricity.

Now it is generally about 400W, plus various devices will not exceed 500W, and the power consumption of 500W for two hours is 1 kWh.

Computers are power-hungry. In general, the power consumption of a computer varies depending on the intensity of the user's use and the environment in which it is used.

Taking a desktop computer as an example, the power consumption per hour is about kWh, and the power consumption for 24 hours a day is about kWh. The power consumption of laptops is about kilowatt-hours (kWh) for 24 hours a day.

The power consumption of a computer mainly comes from its various accessories, such as CPU, motherboard, hard disk, graphics card, monitor, mouse, keyboard, fan, etc., among which CPU and graphics card are the two most power-consuming accessories.

In addition, the usage time, load situation, and usage environment of the computer will also affect its power consumption. If you want to save power, you can minimize the amount of time you spend on your computer, reduce the intensity of your computer's use, or adopt some energy-saving settings, such as turning off the monitor, reducing the frequency of the CPU, etc.

Computers are mid-level power-consuming facilities, and they don't consume much power, so don't care too much about their power consumption.

1 The power consumption of the 3060 graphics card is about 170-200W.

2 CPU power consumption is about 70W.

3 The total power consumption of the rest of the motherboard, hard disk, and fan is about 30W.

4 Therefore, the total power consumption of your machine is around 270-300W.

5 Your telecom source is 500W, according to 80% energy efficiency conversion, the effective supply to the electrical equipment is about 400W, 400W is greater than the electricity consumption of 300W.

6 As a result, your power supply is effective.

7 If you have a high-power independent split water cooler, light bar, radiator in the case, please take a look at the power, if the power exceeds 50W, it is recommended to change to a 600W power supply, if you don't have these, 500W power is enough

8 The big power consumers in the computer are the CPU and graphics card, to see whether the power supply can be driven, the first thing to see is the effective power of the power supply, usually 75 percent to 80 percent, the gold power supply is about 85 percent, according to the 80 percent calculation, the draft is such as the power supply marked 500W, the actual effective power is about 400W, because the power supply itself fan heat dissipation, rectification, etc. also consume power, if marked 400, the actual power is 320W

9 500W power supply effective power is 400W, in addition to the CPU, but also deduct about 50W of the chassis internal motherboard, fan, memory, hard disk power consumption, and then the graphics card, according to your configuration (not considering the high-power radiator, light bar, etc.), 400W-70W-50W is equal to 280W, the power that the graphics card can effectively reach is 280W, the key is tent.

10 This 280W is not available to the graphics card, usually about 200-230W is reserved for the graphics card, because the computer system must have a certain amount of redundant power supply.

11 If you use 500w to power this machine, there is no problem

The power consumption of the computer is also the power consumption of the computer itself, and the power will be lost when the accessories are running.
