PWS-1K24A-1R Supermicro Active 1200W 1U Server PSU

High-Density 1U Redundant Server Power Supply Module with Titanium Efficiency using the PWS-1K24A-1R

The PWS-1K24A-1R is a 1U hot-swap redundant PSU module engineered for dual-PSU server configurations where uptime, predictable power delivery, and serviceability are mandatory. Designed as a standardized replacement power subsystem, it supports dense compute nodes by maintaining continuous operation during PSU servicing or module failure events while keeping electrical characteristics consistent across a fleet.

With 80 PLUS Titanium efficiency, the PWS-1K24A-1R reduces conversion losses to limit rack-level heat output and lower facility power overhead, helping data centre teams protect thermal budgets and PDU capacity planning. PMBus 1.2 enables power telemetry and management integration for platform monitoring, alerting, and capacity governance. The PWS-1K24A-1R includes active cooling via an integrated 40mm fan and is specified for 0–50°C operation, supporting stable behavior in tightly packed 1U environments. Hardware protections including OCP, OVP, UVP, OTP, and SCP help safeguard server backplanes and connected components against abnormal electrical conditions, while EMI Class A compliance supports deployment in regulated enterprise installations.

Why Choose the PWS-1K24A-1R?

The PWS-1K24A-1R provides a strong density-to-reliability profile by combining 1200W capacity with hot-swap redundancy to minimize maintenance windows and reduce operational risk in clustered server racks. It scales cleanly for standardized rollouts, enabling consistent power behavior across mixed workloads while improving energy efficiency metrics at the rack and row level.

Supermicro designs power subsystems with an emphasis on enterprise lifecycle stability, field-replaceable service models, and compatibility with modern rack server chassis standards, aligning component engineering with data centre operational practices.

Key Applications:

• 1U rack server redundant PSU replacement
• Dense compute clusters and scale-out nodes
• Virtualization and private cloud infrastructure
• HPC and AI infrastructure power standardization
• Data centre energy efficiency optimization
