Whether you are dealing with work issues or entertaining your mind and body, you can use your computer. But in the process, do you know the power consumption of your computer? For a medium-sized electronic device like a computer, it doesn’t consume a lot of power, but it shouldn’t be ignored either. As we use computers more often, everyone wants to know how much power a computer consumes. This article will answer your questions about computer usage so that you can feel more comfortable using your computer.
1. How much power does a computer consume?
The main power consuming parts of a computer are the CPU, the display, and the hard disk. Among them, CPU and display are the components that consume the most power. Because the computer’s information processing and the instructions issued by the computer require the CPU, it is equivalent to as long as you are using the computer, your CPU is consuming electricity. One of the computer display is the same, although the display in a short period of time less power consumption, but as long as you turn on the computer, the display will be working. This is especially true for high-performance processors and specialized graphics processors. The power consumption of the computer will be more.
And a computer power consumption, we can not directly estimate how much. Because there are many factors that affect the power consumption of the computer, such as the brand of the computer, the size of the computer, the length of daily use, the use of a series of factors will affect the power consumption of the computer. Therefore, if we use the average value to estimate the power consumption of the computer directly, it will be very different for different people. In this case, we can use specific calculations to further estimate the power consumption of the computer. But before you calculate, you also need to know the following data in advance.
The power of the computer: Usually, the computer label will indicate the relevant parameters of the computer, you can check it directly. If your label is damaged, you can check it on the official website of the computer. In this case, it may be more troublesome, below we have prepared the power of the computer for you in advance for some brands and models.
| Computer Brand | PC model | PC Power（Watt） |
| Lenovo | Dual Core Processors Triple Core Processor Quad Core Processor | 180~200 250~300 350~400 |
| Macintosh | Dual Core Processors Triple Core Processor Quad Core Processor | 150~180 200~250 250~300 |
| Alienware | Dual Core Processors Triple Core Processor Quad Core Processor | 200~220 250~300 300~330 |
| Hasee | Dual Core Processors Triple Core Processor Quad Core Processor | 150~180 200~220 250~280 |
Record computer hours of use: Computer hours of use does not mean the time you are operating the computer, only your computer is still connected to the power supply, which is also considered the computer hours of use, except that it consumes less power when the computer is not in use in standby. You can also directly press CTRL+SHIFT+ESC at the same time, you can view the actual computer hours of use, which includes the performance information displayed on the page where the computer is running, thus helping you to more accurately understand the actual use of the computer.
When you have understood the above two data, you can use the following formula to calculate the computer’s power consumption.
Computer’s power consumption = computer’s power * computer’s usage hours
If the power of your computer is 200W, and your computer is used for 8h per day, then the power consumption of your computer in a day is 200W*8h=1600Wh, which means the power consumption of this computer is 1.6kwh.
2. Tips to reduce your computer’s electricity bill
Optimize computer settings: For computers, you can adjust your display to a suitable level, too high brightness will increase the computer’s power consumption. If your computer is equipped with a backlit keyboard, you can also turn it off when it is not in use in order to reduce the power consumption of your computer.
Using other systems to power your computer: The cost of electricity for computers is partly related to the amount of power consumed by the computer and partly related to the price of electricity in your area. If our computers are already consuming the least amount of electricity, we can use other systems to power our computers, such as solar power systems, which are more common in homes. You just need to make sure that there is sunlight or electricity in your solar battery when your computer is in use. This way, you are using less power from the grid, and you are paying less for electricity.
Choose efficient hardware: Before you buy a computer, you can simply buy a low-consumption processor, which will reduce your computer’s power consumption by a significant amount. You can also use a solid-state keyboard, which has a lower consumption than a traditional mechanical keyboard.
Rational use of the computer: When you use the computer, you may run several programs at the same time in the computer because of convenience, which will increase the load of the computer processor and lead to an increase in power consumption, after you finish the relevant things, you can close the program that you don’t need in time, in order to reduce the power consumption of the computer.
Conclusion:
You can’t estimate the power consumption of a computer by using a single figure directly. The reason is that computers consume different amounts of power for different usage situations. What you can do is to go through the above steps to approximate the power consumption of your computer.
