Bloc d'alimentation Inter-Tech FA-250 250 W

The Inter-Tech FA-250 is a Flex-ATX industrial power supply designed for compact PC systems and embedded applications. It delivers 250 W total power, complies with ATX 12V 2.31, and includes active PFC, wide-range AC input (110–240 V, 50–60 Hz) and relevant EMI/EMV and safety protections. The unit features a sleeved 20+4 pin ATX motherboard cable and suitably long cables for neat installation.

Advantages

The FA-250 provides stable 250 W output with active power factor correction and a minimum efficiency of 82% (product data lists 86% efficiency). Its compact Flex-ATX form factor and a single 40 mm fan enable installation in small enclosures while maintaining airflow. Cable lengths (20+4 pin cable approximately 45 cm, SATA cable approximately 450 mm) and sleeved main connector simplify routing and improve cable management.

How to use

Install the FA-250 in a compatible Flex-ATX or small-form-factor chassis following the chassis manufacturer’s instructions. Connect the sleeved 20+4 pin ATX cable to the motherboard and attach SATA and peripheral cables as required. Ensure the AC input rating (110–240 V) matches the supply and secure the power supply with the provided mounting points. Allow clearance for the 40 mm fan to ensure adequate airflow and cooling.

Recommendations

Use the FA-250 in systems whose total component power draw stays below 250 W, allow adequate ventilation for the 40 mm fan, and verify compatibility with your case mounting and connector layout before installation.
