PWS-1K22-1R Supermicro Active 1200W 1U PSU

High-Efficiency 1U Redundant Power Supply Module for Rack Server Platforms with the PWS-1K22-1R

The PWS-1K22-1R is a Supermicro hot-swap power supply unit engineered for 1U rack server and appliance designs that require predictable power delivery under variable CPU and GPU load. In power-dense nodes, stable rails and fast transient response are critical to maintaining CPU turbo behavior, GPU boost stability, and memory reliability during peak utilization; the PWS-1K22-1R is positioned to support those operational requirements within a redundant PSU architecture.

By integrating the PWS-1K22-1R into a compatible Supermicro chassis, IT teams can align power capacity with modern PCIe expansion and storage backplanes without over-provisioning at the rack level. While platform-specific CPU generation, memory topology, and PCIe lane mapping are defined by the host system, the PWS-1K22-1R directly influences availability and serviceability: hot-swap replacement reduces maintenance windows, and redundant pairing mitigates single-PSU failure scenarios in clustered deployments.

Why Choose the PWS-1K22-1R?

The PWS-1K22-1R provides an enterprise-appropriate density-to-resilience profile for 1U infrastructures where uptime, controlled thermals, and standardized spares strategy matter. Selecting the PWS-1K22-1R supports scalable operations by enabling consistent PSU stocking across fleets, simplifying on-site replacement procedures, and improving continuity for virtualized, containerized, and accelerator-enabled workloads hosted on compatible Supermicro platforms.

Supermicro designs power subsystems with a data centre engineering mindset, emphasizing component compatibility, controlled manufacturing processes, and integration with rack-scale service models. The PWS-1K22-1R follows this approach by targeting predictable installation, consistent electrical behavior, and long-term maintainability within Supermicro server ecosystems.

Key Applications:

• High-availability rack server power redundancy
• Spare PSU standardization for fleet operations
• Data centre break/fix maintenance programs
• Virtualization and container host continuity
