Three brands with the worst power supply

The three brands with the worst power supply are Dafang, Asustek and kinglake.

1. Dafang

Dongguan Dafang Co., Ltd., Dafang, a well-known brand of chassis, a well-known brand of desktop power supply, a well-known domestic graphics card motherboard manufacturer, an important partner of many IT giants such as Intel and AMD, and a well-known domestic IT hardware enterprise, is a complete industrial chain enterprise integrating independent research and development, independent production, independent brand and independent sales.

2. Asustek

Shenzhen Asustek Co., Ltd. is a well-known brand of chassis, a well-known brand of desktop power supply, a famous trademark in Guangdong Province, a famous brand product in Guangdong Province, an outstanding private enterprise in Shenzhen, the vice chairman of China Power Supply Society, a member of China Lighting Society, and one of the larger supporting production bases of PC power supply and household appliances in Chinese mainland.

3. kinglake

kinglake Co., Ltd. is a famous computer hardware manufacturer in Taiwan Province. Its heat dissipation technology is well-known in the industry, and it is mainly engaged in the technology enterprise of radiator/chassis/power supply and digital peripheral products.

main features:

at present, ATX power supply is the most popular power supply specification, which was first introduced by Intel in 1995, and the latest specification version is ATX 12v version 2.31. ATX power supply greatly improved the main power connector at that time. By using++5VSB and PS-ON signals, functions such as software shutdown, keyboard startup and network remote wake-up can be realized.

before ATX12V version 2., the 2-pin connector was first used in the power supply system with ATX external specifications. In order to meet the requirements of high-power CPU, the voltage of 4PIN+12V supplied by ATX 12v to the CPU was increased to+12.8V (+/-12%), which reduced the current intensity of+12v of MAINCONNECT, and in short, it became a configuration of 2Pin+4Pin.

from increasing the output capacity to increasing the heat dissipation setting, and then supporting the latest accessory interface standard at that time, ATX12V has been developing continuously. At present, it is ATX+12V2.3, which improves the output capacity of++12V1 and decreases the output capacity of+12V2. At the same time, it requires the power supply to have a conversion efficiency of 8% or more, and the power factor should be greater than .9, which meets the requirements of energy conservation and environmental protection.
