PWS-920P-1R2 Supermicro Active 920W 1U Server PSU

High-Efficiency 1U Hot-Swap Redundant AC Power Supply Module with the PWS-920P-1R2

The PWS-920P-1R2 is a 920W 1U hot-swap AC PSU module engineered for Supermicro rack servers where power resiliency and predictable serviceability are mandatory. Designed for redundant-capable chassis, the PWS-920P-1R2 supports N+1 or 1+1 power configurations to maintain uptime during module failure or planned maintenance without impacting system availability.

In dense compute nodes running multi-core CPU platforms and GPU-accelerated workloads, stable power delivery directly affects memory integrity and PCIe stability across high-I/O topologies. The PWS-920P-1R2 aligns with these requirements through 80 PLUS Platinum efficiency (up to 94% peak) to reduce rack-level thermal load, and active PFC to improve input power quality under variable utilization. For operational control, PMBus 1.2 enables telemetry-driven power monitoring and configuration, supporting data center automation and capacity planning. Integrated protection mechanisms (OCP, OVP, SCP) help safeguard storage backplanes, PCIe devices, and board-level VRMs during fault conditions.

Why Choose the PWS-920P-1R2?

The PWS-920P-1R2 delivers an enterprise-appropriate density-to-reliability profile for 1U systems by combining hot-swap maintenance with redundant deployment logic. The result is consistent power continuity, reduced mean time to repair, and scalable fleet operations through PMBus-based monitoring in standardized racks and managed power domains.

Supermicro designs power subsystems with an emphasis on data center interoperability, controlled component qualification, and long-term platform support. The PWS-920P-1R2 reflects this approach through efficiency-focused engineering, digital manageability, and compliance alignment (RoHS, REACH) for modern enterprise procurement and sustainability requirements.

Key Applications:

• 1U rack server redundancy upgrades and replacements
• Virtualization and private cloud infrastructure
• HPC and GPU compute nodes with high I/O demand
• Edge data centers requiring serviceable power continuity
