X200 is a 12V input, maximum 200 Watts output DC-DC ATX PSU. It is a low-cost power supply choice for building your mini-ITX computer system. The 12V output rail is connected to the input 12V with two parallel P-channel MOSFETs, to reduce the resistance and therefore the current on 12V output rail is enlarged. A 8-bit microcontroller on board monitors the power ON signal from motherboard and controls the MOSFETs as well as the buck controllers to generate 12V, 5V, 3.3V and -12V for the motherboard. The X200 DC-ATX PSU is compatible with an entire range of mini-ITX motherboards as well as regular motherboards.
