How to choose high power stabilized PC power supply

The basic function of the

power supply in the computer is to convert 220V alternating current into the low-voltage DC power required by the computer, generally it is difficult to see the effect on the performance of the whole machine intuitively. But as a source of power, power supply is actually the basis of stability, if the power quality is not high or insufficient power, but at the same time to drive more hardware equipment, in addition to easy to cause damage to the hard disk, there may be optical drive read disk error, overclocking instability, frequent computer restart, System blue screen and so on. Therefore, consumers to buy power, should be considered in various aspects, especially to pay attention to the quality of power. So for the current 64-bit, dual-core platform, such as high Power PC power supply how to buy it? Four big tricks let consumers have a clear idea of buying.

First recruit: Look at the nameplate of the power supply

Look at the power of the nameplate has two functions: first, see whether the real power of the target; second, to see whether the power of the size of the computer is enough to use. There are a lot of DIY players until the end of the purchase power, it is not clear what they buy is the number of W power supply, not to mention whether the power supply to their own computer to provide enough power. Therefore, the purchase must first see whether the power is real standard.

 


Power nameplate without solid power

See power size, know whether to provide enough power to the computer, you need to estimate the electricity consumption of your own computer.

by calculating the power of different parts, you can roughly estimate the maximum power consumption value of the current 64-bit/dual-core platform configuration:

You don't have to worry about power shortages if you estimate the maximum power consumption of your computer in the range of the real 350W. Xin Valley Power proposed "64-bit system standard 350W power supply", "dual-core Platform standard 2.2 version 350W power" slogan is to meet the actual needs of the market.

Second trick: Look at the fan and cooling system design



Fan on the computer's cooling plays an important role, not only to fully dissipate heat, but also to mute cooling. The high quality power supply fan uses the flame-retardant material, the heat sink is big and thick, the inferior power supply fan uses for the non flame retardant material, the heat sink thin and small. Xin Valley's speed core 535PE overclocking Guardian power supply Cooling mute design is worth reference, it uses 14CM Super mute intelligent temperature control fan, the fan will adjust the speed according to the power supply temperature, behind with the honeycomb-like vent hole, over the wind area than 12 centimeters of fan increased by 36%, but the noise is relatively 12 cm, reduced by 20%, Down to 25dB.

The third trick: look at the weight

Excellent power supply generally feel heavy, inferior power supply feel very light. The power supply, regardless of the line used to design, its weight can not be too light, and the greater the wattage, weight should be heavier, especially through the safety of the standard power supply, an additional number of board 0 components to enhance security stability. Also, the standard thickness of the power supply shell generally has two kinds, 0.8MM and 0.6MM, the use of different materials, weight is also different. But if it is an active power supply, this trick is not appropriate.

The four strokes: look at the price

A power supply in accordance with the normal design and ensure the use of good materials, prices can not be too cheap, good quality 200W power supply should be priced at more than 200 yuan. Recommend that you buy brand power, buy a rest assured, do not map cheap dozens of dollars, after all, all parts of the power to be provided by it, heavy responsibilities.
