The FSP250-50FEB is an industrial-grade Flex ATX power supply that provides 250 W of continuous power for compact PC and embedded system applications. Built to the Intel Flex ATX 12V v1.22 standard, it supports straightforward integration into space-constrained systems. Its compact 81.5 × 40.5 × 150 mm form factor makes it well suited for small-form-factor cases and custom enclosures. The unit supports a wide 90 V to 264 V AC input range for global deployment. Active PFC up to 0.99 helps improve power quality and efficiency. With 80 PLUS Bronze certification, it reduces wasted energy and excess heat during operation. A single +12 V rail with DC-to-DC conversion for minor rails provides stable power delivery for modern components. Smart fan speed control adjusts cooling according to load to keep operation quiet. Broad international safety and EMC certifications make it suitable for worldwide industrial and commercial use.

FAQs
for FSP250-50FEB 250W Flex ATX Industrial AC/DC Switching Power Supply
Flex ATX is a compact power supply form factor intended for space-constrained systems. The FSP250-50FEB measures only 81.5 × 40.5 × 150 mm, making it suitable for tight installations such as small-form-factor PCs, embedded systems, or 1U-style applications.
Yes. The power supply supports a full-range 90 V to 264 V AC input and includes active PFC, so it can be deployed internationally without manual voltage selection.
An 80 PLUS Bronze rated unit typically delivers strong energy efficiency under normal operating loads, helping reduce wasted energy, heat output, and overall power consumption compared with lower-efficiency designs.
A single +12 V rail simplifies power distribution by allowing connected components to draw from one shared 12 V source. This supports stable delivery for higher-demand components and improves compatibility with modern system designs.
The intelligent fan controller adjusts fan speed based on system load and thermal demand. At lighter loads, the fan runs more slowly to reduce noise, then increases cooling only when needed.
The FSP250-50FEB is listed with broad international certifications including CB 62368, CE, FCC, TUV, UL/cUL, CCC, BSMI, UKCA, and KC, supporting safe deployment across multiple global markets.
