PWS-407P-1R
High-Efficiency 1U Redundant Power Supply Module for Rack Servers with the PWS-407P-1R
The PWS-407P-1R is a Supermicro 1U redundant-capable 400W power supply designed to maintain continuous service in rack server fleets where PSU health telemetry and controlled power delivery are required. Built for chassis that implement hot-swap redundancy, the module supports predictable uptime by enabling PSU replacement without taking the node offline when paired in a redundant configuration.
Architecturally, the PWS-407P-1R targets modern x86 compute and storage nodes operating within a 400W-class power envelope, including edge racks where thermal headroom and power efficiency directly affect density. 80 PLUS Platinum efficiency (up to 94% peak) reduces waste heat, helping sustain stable inlet temperatures and fan curves. PMBus 1.2 provides digital monitoring and control for integration into platform management, enabling proactive maintenance workflows and datacenter automation. Active PFC improves power quality at the rack level, while OCP, OVP, and SCP protections harden the platform against fault propagation to boards, backplanes, and attached storage.
Why Choose the PWS-407P-1R?
The PWS-407P-1R delivers an enterprise-grade balance of efficiency, redundancy readiness, and manageability for 1U deployments where serviceability and predictable power behavior drive operational continuity. It supports high node counts per rack by minimizing thermal and electrical overhead, and its PMBus telemetry aligns with scalable monitoring across clustered compute, storage, and edge footprints.
Supermicro designs power subsystems with a focus on reliability, controlled component tolerances, and alignment with datacenter compliance expectations. The PWS-407P-1R follows this engineering approach with digitally monitored operation, active PFC, and regulatory conformity to support consistent fleet standards.
Key Applications:
- 1U rack server redundant PSU replacement
- Standard compute nodes
- Edge rack deployments
- Storage nodes within 400W power budgets
- PMBus-based power and health monitoring
