PWS-2K04F-1R Supermicro Active 2000W 1U Server PSU

High-Efficiency 1U Redundant Rack Power Module with PMBus Management using the PWS-2K04F-1R

The PWS-2K04F-1R is a 2000W hot-plug power supply module engineered for Supermicro 1U server platforms that require N+1 or 1+1 power redundancy without sacrificing rack density. Built around 80 PLUS Titanium conversion efficiency and Active PFC, the PWS-2K04F-1R is designed to reduce power loss and thermal load in high-density racks where PSU efficiency directly influences cooling headroom and overall facility power budgeting.

For operations teams, the PWS-2K04F-1R integrates PMBus 1.2 telemetry and control, enabling power, voltage, current, temperature, and status reporting for fleet-level monitoring and policy-driven power management. This allows tighter correlation between workload behavior and power delivery, supporting predictable capacity planning and faster fault isolation. Protection features such as overload protection and under-voltage protection (UVP) help maintain stable service under transient conditions common to multi-tenant and bursty compute environments.

Why Choose the PWS-2K04F-1R?

The PWS-2K04F-1R delivers a strong density-to-reliability profile for enterprise 1U deployments by combining redundant hot-swap serviceability with digitally managed power. The PWS-2K04F-1R supports consistent uptime targets through fast replacement workflows and controlled power behavior, making it well-suited for standardized rollouts where scalable maintenance and uniform monitoring are mandatory.

Supermicro designs power subsystems with data centre integration in mind, emphasizing efficiency, electrical safety margins, and interoperability with modern rack monitoring practices. With compliance to RoHS and REACH, the PWS-2K04F-1R aligns with procurement requirements while maintaining enterprise-grade operational stability.

Key Applications:

• 1U server redundancy upgrades and spares
• High-density virtualisation clusters
• Private cloud and scale-out infrastructure
• Managed hosting and multi-tenant racks
• Edge micro data centres with constrained cooling
