BP009EU Be Quiet! System Power 11 Active 450W ATX PSU

Efficient ATX 3.1 EPS Power Supply Unit for Cost-Controlled Tower Platforms with the BP009EU

The BP009EU is an ATX 3.1 compliant EPS form factor PSU designed for stable power delivery in entry GPU workstations, office desktops, and embedded ATX/EPS appliances where predictable electrical behavior matters more than peak density. With a 450W single-PSU, non-redundant architecture and 80 PLUS Bronze efficiency, BP009EU supports balanced CPU-and-GPU configurations while controlling thermals and operating cost across large tower fleets.

BP009EU integrates fixed, non-modular cabling to reduce connector resistance and simplify standardized builds, providing the core rails required for modern mainboards and add-in cards. Expansion planning is supported via 2x 6/8-pin PCIe for entry discrete GPUs, while 5x SATA and 1x 4-pin IDE enable mixed SSD/HDD and legacy peripheral footprints common in SMB refresh cycles. The 150mm fan targets low acoustic impact at 19.1 dB(A), and power management features including ErP Lot 6 and C6/C7/Modern Standby help keep idle draw controlled for always-on endpoints.

Why Choose the BP009EU?

BP009EU is engineered for reliable, repeatable deployment in volume desktop and edge programs where qualification time, electrical compliance, and service predictability are key. Its ATX 3.1 alignment supports current platform power expectations, while the 450W capacity and fixed harness design deliver a practical density-to-performance ratio for cost-focused rollouts without overprovisioning.

be quiet! focuses on electrically robust PSU design with an emphasis on stable regulation, acoustically considerate cooling, and adherence to contemporary platform standards. This approach aligns BP009EU with modern data centre-adjacent environments such as edge closets and office IT rooms, where efficiency, low-noise operation, and consistent integration are operational requirements.

Key Applications:

• Entry-level GPU workstation builds
• Office and SMB desktop fleets
• Edge appliances with ATX/EPS compatibility
• General-purpose compute towers
