PWS-903-PQ Supermicro Active 900W ATX PSU

High-Performance ATX Server Power Supply featuring 80 PLUS Gold efficiency with the PWS-903-PQ

The PWS-903-PQ is a 900W ATX server power supply engineered for CPU-centric and GPU-capable workstation or rack deployments where a single, non-redundant PSU is the appropriate availability model. With active PFC and 80 PLUS Gold efficiency, the PWS-903-PQ is designed to reduce conversion losses under sustained load profiles typical of enterprise compute nodes and edge racks.

Architecturally, the PWS-903-PQ supports modern multi-rail power distribution needs through a dense connector set aligned with contemporary CPU platforms and PCIe expansion. Multiple 12V auxiliary outputs enable stable delivery to motherboard EPS12V domains and add-in cards, while mixed PCIe 6-pin and 6+2-pin cabling simplifies integration of GPUs or high-power PCIe accelerators without adapter chains. A 120mm fan and 0–50°C operating envelope support predictable thermals in tower and chassis environments where acoustic-to-cooling balance and continuous operation matter.

Why Choose the PWS-903-PQ?

The PWS-903-PQ provides a pragmatic density-to-power ratio for single-PSU builds that prioritize efficient power conversion, clean cabling, and serviceable integration over redundant topologies. For enterprise IT, the PWS-903-PQ supports scalable standardization across ATX server and workstation fleets by delivering consistent connector availability for CPU power planes and PCIe-powered devices, helping reduce build variance and validation effort.

Supermicro designs power subsystems for long-duty-cycle data centre operation, emphasizing electrical stability, component qualification, and compatibility with standard chassis and motherboard ecosystems. This engineering approach aligns the PWS-903-PQ with modern infrastructure expectations for efficiency, maintainability, and predictable deployment behavior.

Key Applications:

• ATX server and workstation builds
• General compute CPU-only nodes
• GPU-ready tower systems
• PCIe accelerator expansion platforms
