PWS-1K23A-1R
High-Efficiency 1U Redundant AC Power Supply Module with PMBus Telemetry using the PWS-1K23A-1R
The PWS-1K23A-1R is a Supermicro 1U redundant, hot-swap AC power supply module engineered for rack server platforms that depend on continuous power delivery and rapid serviceability. Designed as a drop-in PSU replacement for supported Supermicro chassis power backplanes, it aligns with enterprise change-control practices by enabling maintenance without extended downtime and by preserving N+1 power availability at the chassis level.
With 1200W capacity and 80 PLUS Titanium efficiency, the PWS-1K23A-1R targets dense compute nodes where heat, airflow, and operating cost are constrained. PMBus 1.2 management provides power telemetry and control integration into standard out-of-band monitoring workflows, supporting proactive operations through visibility into power draw and PSU health. Protection functions including OCP, OVP, UVP, SCP, and OTP help safeguard server boards, PCIe expansion, and storage backplanes from electrical anomalies, while active PFC improves input-side power quality in data centre circuits.
Why Choose the PWS-1K23A-1R?
The PWS-1K23A-1R delivers an enterprise-ready density-to-efficiency profile for 1U systems, pairing redundant hot-swap service design with high-efficiency conversion to reduce thermal load per rack unit. It supports scalable operations by standardising spares across compatible Supermicro platforms and by enabling policy-driven monitoring through PMBus, improving predictability in mixed workload clusters and multi-tenant environments.
Supermicro designs power subsystems to match modern data centre requirements for reliability, manageability, and controlled thermals, with validated integration across server chassis and power distribution topologies. The PWS-1K23A-1R follows this engineering approach to support consistent behaviour under continuous duty cycles.
Key Applications:
- Rack server PSU replacement and spares
- High-density 1U compute clusters
- Virtualisation and private cloud infrastructure
- HPC and AI node power redundancy
- Data centre efficiency optimisation projects
