Description

X300 is a small size, fanless, high power DC-DC ATX PC power supply unit (PSU) designed for use with mini-ITX PC.  X300 accepts 16-24V wide-range DC input and provides a cool, silent 300 Watts of power for small size PC designs. With the two current mode synchronous step-down controllers operating in 180° out of phase, X300 provides as much as 20 Amp current on the 12V output rail, facilitating using the high performance graphic card. The PSU is compatible with an entire range of mini-ITX motherboards as well as regular motherboards.
