PPA5008400 FSP FSP500-50FDB Active 500W Flex-ATX NAS PSU

Compact Flex-ATX Server Power Supply engineered for high-efficiency edge builds with the PPA5008400

The PPA5008400 is a Flex-ATX 500W enterprise PSU designed for compact NAS appliances and space-constrained edge or branch servers where power density, electrical stability, and predictable thermals are decisive. It provides regulated DC output through a standard 24-pin ATX plus EPS12V/ATX12V CPU power, enabling deployment with modern x86 server-class motherboards in short-depth chassis.

With 80 PLUS Gold efficiency, Active PFC, and ErP Lot 6 alignment, the PPA5008400 reduces waste heat and input draw in always-on storage and virtualization nodes, supporting tighter acoustic and thermal envelopes. PCIe 6+2-pin support addresses add-in accelerators, high-port NICs, or HBA cards, while multiple SATA and peripheral connectors simplify mixed-drive power distribution without additional backplane adapters. Integrated OCP, OVP, OTP, OPP, and SCP protections harden the power domain against transient load events typical of drive spin-up and burst I/O, and the 40mm fan is tuned for the airflow constraints of Flex-ATX enclosures; non-modular cabling prioritizes electrical integrity over cable management.

Why Choose the PPA5008400?

The PPA5008400 delivers a strong density-to-efficiency ratio in a 40.5mm-wide Flex-ATX footprint, making it well-suited for standardized edge platforms where serviceability and consistent power behavior matter more than oversized capacity. Its connector set and protection stack support scalable storage and network expansion while maintaining enterprise reliability expectations for 24/7 operation.

FSP designs power platforms with an engineering focus on conversion efficiency, protection coverage, and compliance readiness for modern data centres, enabling stable operation under continuous load profiles and frequent power-state transitions.
