The working process of an ATX auxiliary power supply can be divided into several stages. Firstly, when the main power supply is connected, the power supply circuit is activated. This circuit is responsible for converting the AC power from the main supply into DC power. The DC power is then...
through the high-frequency filter circuit output a total of six sets of DC voltage: +5V (25A), - 5V (0.5A), +12V (10A), - 12V (1A), +3.3V (14A), +5VSB (0.8A). In order to prevent the overcurrent or overvoltage of the load from damaging the power supply, a fuse is arran...

As standard, our ATX power supplies come with top of the range features including ON/OFF controls, 80 plus verification, power factor correction and a full range of short circuit, over voltage, and over load protection. These ATX power supplies are also quiet. Keeping noise operation to a ...
ATX power changed obviously, such as the abolition of the power switch on the power supply and the necessary AT control over the mainboard power switch, and the power also added a standby circuit provides the voltage to the power supply main circuit and the motherboard to implement power wake...
