How to check your computer power consumption

In the new installation or to upgrade the hardware for the old computer, we often have to understand the computer power of W. General new installed according to the CPU, video card, memory, hard disk, motherboard power consumption, to calculate the appropriate size power of the power supply, while the old computer upgrade hardware, is mainly to see the upgrade of new hardware to increase the power consumption, on whether the power can also carry the move, if the power consumption is small, then the power needs to be replaced

How to look at the computer power supply W View your computer power consumption method

The following article mainly for you to share how to see how many Watts computer power and how to view the computer power consumption, I hope that the new installed or intended to upgrade the computer users, help.

First, how to see the computer power supply W

For how to view the power of the computer is how much w, here should be noted that the power of the rated power, not the maximum power.

So, how to look at the power of the rated power? This method is very simple, for example, according to the power of the brand model, and then go to the Internet or electronic business platform to inquire about the product, and then look at the power parameters, you can know. Below we take "Patriot Dark Knight 470DK power" as an example, by looking at the product parameters, you can see the power supply rated power, as shown in the following figure.

Note that many of the power supplies like to mislead users on the name, such as the Patriot Dark Knight 470DK power supply, the rated power is 320W, but the name of the 470 words, many people will mistakenly think this power rating is 470W, but the actual 470W is the peak power, The equivalent of this power can reach the limit value (WwW.PC841.COM computer Pepsi net), and the normal operation of the computer can not be in the power limit, the power can not withstand the operation of the ultimate power, so the computer power supply is mainly to see the rated power, the peak can be neglected to see the basic.

In addition, we can view the power supply by looking at the nameplate on the surface of the power supply, the general brand Power will be on the surface of the power supply plate clearly marked rated power, you can open the power supply chassis or power down to view. For example, this "Titanic vp500p" rated power is 500W, we can see on its surface nameplate, as shown in the following figure.

The above is to see the power of how many w of the two methods, computer power is generally not tested by computer software, but other hardware can. Below we look at our own computer power consumption method, specifically to see.

Second, how to view the computer power consumption

A computer, the hardware that consumes electricity mainly has: CPU, video card, memory, hard disk, motherboard, optical drive and monitor and so on. If you want to see the computer power consumption, the most stupid way is the CPU, video card ... Monitor and other hardware thermal design power consumption added up, basically is the computer's rated power consumption.

But this is a lot of trouble, because we need to know the CPU, graphics, memory, hard disk, motherboard, CD-ROM and monitor hardware all models, and then according to the product model to find power, and then stack the calculation will come out, but this will be very troublesome.

The following computer Pepsi Network Small compiled to teach you a simple way, with the help of computer hardware detection tools, you can easily understand their power consumption. The following is an example of the "Master Lu" tool.

1, in need to view the power of the computer to download the installation of the "Master Lu" tool, then open the run, and then switch to the "Hardware Detection" interface, and then click on the bottom left of the "power estimate", as shown in the following figure.

2, after the master will automatically detect the computer CPU, graphics, motherboards, hard disk, memory and other models, and will show hardware power consumption, we simply choose the size of their own display can be used (the desktop does not have to choose the display), and then the bottom can see the estimated computer power consumption. For example, the laptop is 14 inches, the calculated power consumption is about 112W, as shown in the following figure.

Because the small weave uses the notebook, therefore the power consumption is not big. If it is a desktop computer, then the power consumption will be relatively large.

In this case, I believe that everyone on how to view the power and how to view their computer power consumption methods, mastered the two computer knowledge, later installed or computer hardware upgrades, you can determine whether the power supply can meet the requirements.

Ps.diy installed power supply rated power, generally reserved a certain amount of room, generally reserved for 50W. What do you mean? For example, a desktop computer CPU, graphics, memory, motherboard, hard disk, such as hardware power stack is 250W, then select the power supply, the general to choose 300W or more power of the rated power.
