X310 is a small size, fanless, high power DC-DC ATX PC power supply unit (PSU) designed for use with mini-ITX PC. X310 accepts 16-28V 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, X310 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.
Compared with X300 DC-ATX PSU, X310 enlarges the input voltage to 28V and has different output connector layout. Both X300 and X310 have the same functions.
|Minimum Input Voltage
|Maximum Input Voltage
||+28.00V (over-voltage protecting occurs at +28.00V)
|Input Current Limit
|Reverse Input Protection
The recommended input voltages are 19V, 19.5V, 20V or 24V.
Maximum Power Characteristics
Forced air ventilation is required for load larger than 180 Watts. For fanless or improper ventilation operation, de-rate the output current of each rails by at least 30%.
