PWS-504P-1R2 Supermicro Active 600W 1U Server PSU

High-Performance 1U Redundant Hot-Swap Server Power Supply Module with the PWS-504P-1R2

The PWS-504P-1R2 is a Supermicro 1U redundant hot-swap AC power supply module engineered for monitored rack server platforms where power integrity and serviceability are operational requirements. Designed for redundant-capable chassis, the PWS-504P-1R2 enables rapid in-rack replacement to maintain uptime while supporting power-domain efficiency targets in dense deployments.

With 80 PLUS Platinum efficiency up to 94% peak, the PWS-504P-1R2 reduces conversion losses and thermal load, directly improving airflow planning and fan policies at the system level. PMBus 1.2 integration provides telemetry and control for power, voltage, current, and status reporting, allowing alignment with modern out-of-band management and automated maintenance workflows. An active PFC design supports stable input behavior, while OCP, OVP, and SCP protection mechanisms help shield downstream server components during fault conditions; the integrated 40 mm fan supports local thermal management within 1U mechanical constraints.

Why Choose the PWS-504P-1R2?

The PWS-504P-1R2 is optimized for high-availability 1U infrastructures that require predictable redundancy behavior, controlled servicing, and power monitoring at scale. By combining hot-swap operation with Platinum efficiency and PMBus-managed visibility, the PWS-504P-1R2 supports a strong density-to-reliability profile for enterprise racks and standardized spares strategies.

Supermicro designs power subsystems to align with data centre operational standards, focusing on validated interoperability, robust protection circuitry, and service-friendly module form factors. This engineering approach supports consistent lifecycle management across mixed server fleets and monitored power domains.

Key Applications:

• 1U rack server redundant PSU replacement
• Data centre spares and maintenance stocking
• PMBus-monitored enterprise server platforms
• High-efficiency power domains in dense racks
