FSP FSP250-50FEB alimentatore 250 W Flex ATX

The FSP FSP250-50FEB power supply unit 250 W is a Flex ATX form-factor PSU designed for compact desktop systems and specialized small-form-factor builds. Rated for 250 W total output, it supports a wide AC input voltage range of 90–264 V and operates at 47–63 Hz, making it compatible with international mains supplies. The unit is 80 PLUS certified and provides an energy-efficient power source with an active cooling solution that uses a 40 mm fan to maintain stable temperatures under typical loads.

Advantages

This PSU provides reliable 250 W continuous power in a compact Flex ATX enclosure suitable for space-constrained systems. Its 80 PLUS certification and measured efficiency around 85% help reduce wasted energy and heat generation. The wide AC input range allows operation across different regions without additional voltage selection, and the built-in 40 mm fan delivers targeted cooling to preserve component longevity. The product holds common safety and environmental certifications such as RoHS, CE, and FCC for regulatory compliance.

Suitable for

• Small-form-factor desktops and compact HTPCs
• Embedded systems and industrial PC applications with limited internal space
• System builds requiring a reliable low- to mid-power PSU rated at 250 W
• Upgrades where compatible Flex ATX power supply replacements are needed

How to use

Install the FSP250-50FEB into a compatible Flex ATX mounting location in your chassis, securing it with the appropriate screws and ensuring proper orientation for airflow. Connect the unit to the motherboard and peripheral devices using the supplied power cables and connectors that match your components. Before powering on, verify that the system wiring is correct and that the AC mains voltage falls within the supported 90–264 V range. Allow for adequate ventilation around the 40 mm fan to ensure effective cooling during operation.

Recommendations

For reliable operation, use this PSU in systems where the combined component power draw remains well below the 250 W rating to allow headroom for peak loads. Keep system vents and the 40 mm fan area free of dust and obstructions; periodic cleaning improves cooling performance and longevity. When building or upgrading, confirm Flex ATX compatibility and connector availability to ensure straightforward installation.
