PWS-751P-1R Supermicro Active 750W 1U Server PSU

High-Efficiency 1U Redundant Server Power Supply Module with PMBus Telemetry using the PWS-751P-1R

The PWS-751P-1R is a 750W AC power supply module engineered for Supermicro 1U rack server platforms that require redundant power delivery with predictable thermals and controlled power quality. Designed for density-focused compute and storage nodes rather than discrete CPU or GPU upgrades, the module supports stable rail regulation for modern multi-core CPU boards, PCIe expansion backplanes, and high IOPS storage configurations where power excursions must be contained.

With 80 PLUS Platinum efficiency, the PWS-751P-1R reduces conversion losses in high rack-density deployments and helps maintain fan curves and inlet temperature margins under sustained load. PMBus v1.2 monitoring enables integration into platform management for remote telemetry, alerting, and lifecycle tracking across fleets. Active PFC improves input power factor in shared PDU environments, while protection features including OVP, OCP, and SCP provide fault containment to safeguard system boards, PCIe devices, and storage cages during abnormal events or service operations.

Why Choose the PWS-751P-1R?

The PWS-751P-1R supports an enterprise redundancy strategy in 1U chassis by enabling hot-swap serviceability and consistent power behavior across standardized server builds. It delivers a strong density-to-performance profile for scale-out nodes, improves operational continuity with digital observability, and fits deployment models that prioritize repeatable configuration, rapid replacement, and centralized monitoring for large server populations.

Supermicro designs power subsystems to align with data centre operating requirements, focusing on validated interoperability, controlled component selection, and reliability under continuous duty cycles. The PWS-751P-1R follows this approach with efficiency, telemetry, and compliance to modern environmental standards including RoHS and REACH.

Key Applications:

• 1U redundant power configurations
• Scale-out compute nodes
• High-density storage servers
• Remote PSU telemetry and fleet monitoring
