How to choose the power of computer host

1. Where does the power of the computer come from?

First of all, to know how much power you have configured, first think about the main power of the computer in which respect, the computer also known as the computer, as the name implies is used for scientific operation of the tool, bear the main part of the calculation of natural CPU, with the technology, and the auxiliary operation of the equipment-graphics, today, cpu+ The graphics card basically still occupies our computer power total of more than 90%, understand your CPU and graphics power consumption naturally to the power needs at hand.

2, Overall, the PC's power consumption is gradually reduced

You must have heard "the latest Samsung 14 nm" In many mobile ads, "The latest TSMC 16 nano-technology, such as the words, nano refers to the size of the transistor, basically all the chips are made of this transistor, the more the transistor more theoretical performance is stronger, the higher the natural power consumption.

Today, the CPU and graphics technology are fully entered the 14/16 nanometer era, the average level of the process, the CPU's power consumption is not more than 100W, most of the graphics card power consumption is maintained under 200W, can be very certain one thing is: Our computer performance in the continuous improvement, Power consumption has been declining, this is the inevitable development of science and technology.

3. What is the main consumer's computer power consumption?

According to the domestic hardware portal Zol investigation, take 2015 years of data as an example, the most attention of the graphics card has 65% concentrated in the following 2000 yuan, of which the following is occupied by 1/3, that is, at least 3/4 of the user's video card power consumption is not more than 200W (in fact, there is very little high-end graphics power consumption over 250W) , 100W power consumption below the graphics user is absolutely mainstream.

Take a set of 15 years of high-end gaming platform for example, i7-6700k power consumption of 140W (maximum), the typical value of about 100W, and gtx980ti power consumption of about 250W (maximum), the typical value of 200W, plus other hardware power consumption, the largest machine power consumption of about 400W, Using a 550W power supply is just right.

4, low power generation, how to choose the power?

The power consumption of the hardware is decreasing, does it mean that we choose the power is also getting smaller? This sentence is not entirely correct. First of all, the power supply has a conversion rate parameter, that is, the process of converting the mains to direct current, the process will generate electricity loss, the main performance is heating, increase the cost of electricity, according to the current level of power, the power supply in 50% of the time the conversion rate is the highest, the most

Suppose you configure a machine power consumption about 300W of computer, and then also choose 300W power supply, then the load will be long-term high power supply, so the power has serious damage, instead of a 600W power supply, load for a long time only about 50%, so that not only greatly save electricity, And the most stable and safe operation, but also facilitate the future of some hardware replacement and upgrade.

5. Select the power supply according to the platform

Overall, about "How much power does my configuration choose?" This kind of question, depending on the platform you choose, can be roughly divided into:

1, low-end office home: using the I3 level of the CPU, using a nuclear or not higher than the thousand independent graphics card, low power, recommended rated 300W power supply.

2, Midrange game platform: the use of four core processors + no more than 2000 yuan in the independent graphics card, you can play online games and play some special effects are not too high 3D games, the overall power consumption around 200-300w, the recommended choice of rated 450w~650w power supply.

3, the limit of the temperature host: I7 level of CPU and 2000 yuan of independent graphics, power Power recommended 500W start, this part of the players are generally experienced diyer, power demand is very clear, more fancy is the quality of power, believe that similar to the ultimate Firepower 80PLUS Platinum certification Such a power supply to their standards.

To sum up, 500W about the power supply is more mainstream, then, 500W about the power of which section good? Small series for everyone recommended Zhenhua Kingdee GX550, this product in the same level of power, is absolutely said to be a superior product, not only has the gold-plus performance, and almost close to platinum efficiency. The rated power of this product is 550W, the use of active PFC design and efficient one-way +12v output design, to avoid dual +12v power supply all the way idle, and this power also has multiple protection: overcurrent/Overvoltage/overload/short-circuit protection.
