PWS-702A-1R Supermicro Active 700W 1U PSU

High-Availability 1U redundant hot-swap power module for rack servers with the PWS-702A-1R

The PWS-702A-1R is a 1U redundant AC hot-swap power module designed as a spare or replacement PSU for Supermicro 1U server platforms, enabling continuous operation during PSU servicing or unexpected power module failure. In dual-feed 100–240V AC environments, the PWS-702A-1R supports resilient power delivery aligned with modern rack-level availability targets and standard data centre power distribution.

With a 700W AC input design and an efficiency profile up to 88% at peak load, the PWS-702A-1R helps reduce wasted power and thermal load in dense 1U deployments where airflow and acoustic budgets are tightly managed. Its hot-swap modular construction and controlled cabling approach improve serviceability, minimizing mean time to repair and supporting predictable maintenance workflows for systems running virtualized infrastructure, edge nodes, or clustered compute that require stable power redundancy rather than platform redesign.

Why Choose the PWS-702A-1R?

The PWS-702A-1R provides a practical density-to-availability advantage by delivering redundant 1U power in a field-replaceable module that aligns with enterprise change-control and uptime objectives. It enables scalable operations through consistent spares strategy across compatible Supermicro racks, maintaining power redundancy without extending maintenance windows, and supports reliable operation across global AC ranges for standardized deployment.

Supermicro designs power modules with an engineering focus on operational continuity, component compatibility, and service-centric mechanics. The PWS-702A-1R reflects this approach through redundant hot-swap architecture, compliance with RoHS and REACH requirements, and integration suited to modern data centre standards for maintainable 1U server estates.

Key Applications:

• 1U rack server PSU replacement and spares
• Redundant power for virtualization hosts
• High-availability edge and branch compute
• Clustered infrastructure maintenance operations
