PWS-982P-1R Supermicro 980W 1U Server PSU

High-Performance 1U Redundant Hot-Swap AC Power Module for resilient rack power with the PWS-982P-1R

The PWS-982P-1R is a 980W-class Supermicro 1U redundant hot-swap AC power module designed to stabilize enterprise compute and storage nodes where uptime is non-negotiable. In paired configurations, the PWS-982P-1R enables N+1 or 1+1 power architectures that keep platforms online during a PSU fault or planned service, supporting continuous operation in virtualized clusters and private cloud racks.

Architecturally, the PWS-982P-1R focuses on efficient AC-to-DC conversion and predictable power delivery for dense 1U systems hosting modern CPU and GPU workloads. With 80 PLUS Platinum efficiency up to 94% at peak, the PWS-982P-1R reduces conversion losses, lowers thermal load, and helps maintain stable fan curves and chassis acoustics under sustained utilization. The hot-swap design aligns with serviceability requirements for PCIe expansion, NVMe-heavy storage topologies, and high-memory configurations by minimizing maintenance windows and simplifying capacity planning at the rack level.

Why Choose the PWS-982P-1R?

The PWS-982P-1R provides a practical density-to-reliability balance for 1U deployments by enabling redundant power without increasing chassis footprint. For enterprise operations, the PWS-982P-1R supports standardized spare strategies, predictable failure domains, and rapid replacement procedures that match high-availability design patterns across compute, storage, and virtualization tiers.

Supermicro designs power modules with an emphasis on platform integration, electrical and thermal reliability, and data centre compatibility. The PWS-982P-1R follows this engineering approach with compliance to RoHS and REACH, supporting modern procurement and sustainability requirements while maintaining consistent operational characteristics across supported Supermicro systems.

Key Applications:

• 1U rack server N+1 and 1+1 power redundancy
• Virtualization and private cloud high availability
• Enterprise compute and storage nodes
• Maintenance-friendly hot-swap service operations
