PWS-2K04A-1R Supermicro Active 2000W PSU

High-Density 1U Redundant Hot-Swap Power Supply Architecture with the PWS-2K04A-1R

The PWS-2K04A-1R is a 2000W redundant hot-swap PSU module designed for 1U rack platforms where sustained power delivery and serviceability are mandatory. In CPU- and GPU-dense nodes, the power subsystem must maintain stable rails under rapid transient loads; the PWS-2K04A-1R targets this requirement with active PFC and an efficiency profile aligned to 80 PLUS Titanium, reducing conversion losses and lowering thermal burden in high-density chassis.

For modern server architectures, power telemetry is as critical as raw capacity. The PWS-2K04A-1R implements PMBus 1.2 for digital monitoring and control, enabling integration with platform management for power budgeting, fault correlation, and fleet-level operational visibility. Its hot-swap design supports N+1 or N+N redundant configurations, minimizing MTTR during maintenance windows while keeping PCIe expansion, storage backplanes, and accelerator subsystems within validated power envelopes.

Why Choose the PWS-2K04A-1R?

The PWS-2K04A-1R delivers a practical density-to-performance ratio for 1U deployments by consolidating 2kW capability into a serviceable redundant module that supports continuous operations. Using the PWS-2K04A-1R helps standardize spares across compatible Supermicro server families, streamlines on-site replacement procedures, and enables scalable rollouts where predictable power behavior and management-plane reporting are required.

Supermicro designs power modules with data center lifecycle considerations, emphasizing validated electrical behavior, thermal compatibility within constrained chassis, and interoperability with enterprise monitoring standards. Regulatory compliance (UL/cUL, CB, CCC, BSMI, RoHS) supports global deployment requirements and consistent procurement processes.

Key Applications:

• Rack server PSU replacement and spares
• High-density CPU/GPU compute nodes
• Redundant power architectures in 1U systems
• Data center power telemetry and budgeting
