Computer power selection. Come on

Athlon X3 does not have the model of 460, the highest is 455, the difference is that the operating frequency is different, such as 440 is 3GHz, 450 is about 485 yuan, 450 is about 555 yuan.

Boxed CPU sends fan, bulk does not.

It's enough to play games 440, and the 350W power supply is enough, so choose Hangjia multi-core X2.

There are very few CPUs that can be selected by CPUs, the price difference is not large, CPUs are very important, and it is expensive to buy them.

The power supply needs to be equipped with 350W, and you need to buy the rated 350 version.

Huntkey Wide King 2 (version), rated power: 350; 300 yuan.

AMD ATHLON II X3 460 Frequency: ; 540 yuan.

AMD Athlon® II X3 440 clock: 3GHz; 475 yuan.

The box is with the original fan; Bulk should be equipped with a fan. In addition, there is a difference in the warranty period.

With Haiyun power supply, Annami pirate ships can be.

A computer to start normally is inseparable from the computer power supply, the computer power supply to maintain the power of the computer host, in which computer many parts are also very important, is an indispensable position, so how to choose a good computer power supply?

1. The shell design of the power supply: the shell of the power supply will affect the shielding of electromagnetic waves and the heat dissipation of the power supply. If the shielding effect of electromagnetic waves is not good, it will have a certain impact on people's health, and the heat dissipation function will affect the life of the power supply.

At present, the power supply shell on the market is generally made of galvanized steel, and some are made of all-aluminum, so consumers can distinguish its material as long as they estimate the weight of the power supply.

2, the power of the open card view: the power of the open card view is also very important, usually in the consumer to view the power supply of the open card, will check its rated power, to see whether to reach 80plus, but the rated power and 8080plus does not represent the quality of the power supply, 80plus is only the conversion efficiency, the role is to save power, if the power supply has passed the FCC or UL certification, just on behalf of the power supply has a higher quality.

3. Power cable and fan: In the purchase of power supply, it is not that the longer the wire, the better, on the contrary, the longer the wire, the lower the corresponding conversion efficiency, so it is better to choose the right length, in addition, we should also pay attention to the fan of the power supply, in the case of the same fan speed, the larger the fan, the more sufficient the air volume, the better the heat dissipation performance of the power supply, so we should also pay attention to the size of the fan when choosing the power supply.

4. The internal components of the power supply: when purchasing the power supply, we should also pay attention to the internal components of the power supply, usually the power supply can not be opened, but we can observe the internal components of the power supply through the heat dissipation hole of the power supply. It is best to choose a power supply with an active PFC design.

Because its design process is more complex, it is usually not prone to counterfeit and shoddy products. Then look at the material of the power supply, see whether the PCB material is used, because it has the best fire performance, and finally look at its circuit, whether the 16th or 18th wire rod is used, this kind of wire has strong bearing capacity and high safety factor.
