PWS-741P-1R Supermicro 740W 1U PSU

High-Availability 1U Redundant Hot-Swap AC Power Supply engineered for Supermicro platforms with the PWS-741P-1R

The PWS-741P-1R is a 1U redundant hot-swap AC power supply designed to maintain uninterrupted power delivery in Supermicro rack systems where uptime and serviceability are operational requirements. Built for dense deployments, it supports wide-range 100–240V AC input and high-efficiency conversion to reduce rack-level thermal load and upstream power provisioning pressure.

Within a redundant power architecture, the PWS-741P-1R enables N+1-style availability for compatible 1U chassis using a card-edge/backplane connector, allowing in-service replacement without taking the server offline. Active PFC and 80 PLUS Platinum efficiency (up to 94% peak) improve power quality and lower losses, while PMBus v1.2 telemetry supports platform-level monitoring, trending, and proactive maintenance. Integrated protection against over-voltage, over-current, and short-circuit events helps safeguard system boards, PCIe expansion, and storage backplanes from power anomalies that can destabilize enterprise workloads.

Why Choose the PWS-741P-1R?

The PWS-741P-1R is selected for its reliability profile and operational fit in 1U environments where density-to-availability trade-offs are unacceptable. By combining redundant hot-swap mechanics with efficient conversion and manageability, the PWS-741P-1R supports scalable rack deployment strategies, simplifies spares standardisation, and shortens mean time to repair during power-domain service events.

Supermicro designs power subsystems with a focus on data centre serviceability, electrical safety, and predictable behaviour under variable load. The PWS-741P-1R aligns with modern enterprise requirements for monitored, redundant power in compact chassis, backed by a >200,000-hour MTBF target for continuous operation.

Key Applications:

• 1U server PSU replacement and spares standardisation
• High-availability rack deployments with redundant power domains
• Virtualisation and private cloud nodes
• Edge and branch compute with constrained maintenance windows
• Storage and network appliances requiring hot-swap serviceability
