Knowledge of computer chassis power

Chassis power knowledge has always been a less important link, but also a business profit most of the link, in the computer prudential installed we often like to choose the chassis power combination recommended by merchants, in fact, we have not to carefully study, the business sector verbally said to you than 350w power, in fact, are the cheapest Shanzhai power, The actual rated power must be less than 300w, the cost is only about 60, the price is basically doubled to you. Impure power supply will be a variety of computer failures buried foreshadowing, before we have repeatedly stressed this issue, so I recommend the power supply as much as possible to buy some word-of-mouth stability better, power must be able to meet the needs of the machine.

Power of three kinds of power, please pay attention to distinguish, it is easy to be JS fooled a little! respectively: Rated power, maximum output power and peak power. PFC is divided into active type and passive, and the active type is more energy-saving. 3 C: Usually the power is marked, fake fake except (of course also can forge, in fact, put a label), 3C refers to China compulsory certification.
