Supermicro PWS-2K05A-1R 2000W 1U Redundant Power Supply

The Supermicro PWS-2K05A-1R is a high-efficiency 2000W redundant power supply module designed for mission-critical AI and GPU-accelerated computing environments. Built to 80 PLUS Titanium efficiency standards, this unit delivers superior power conversion with minimal heat generation—a critical requirement for densely-packed GPU server configurations where thermal management directly impacts performance and reliability. The redundant architecture enables N+1 failover capability, ensuring uninterrupted power to compute nodes even during single PSU failure events, a mandatory feature for production AI inference and training clusters.

Architecturally, the PWS-2K05A-1R implements advanced power factor correction (PFC) and multi-rail output topology optimized for modern heterogeneous compute loads mixing CPUs, GPUs, and storage controllers. The 1U form factor integrates seamlessly into standard 19-inch rack infrastructure, enabling space-efficient deployment within hyperscale and enterprise AI data centers. Hot-swap capability and redundant module support reduce mean time to repair (MTTR) and eliminate unplanned downtime during maintenance cycles.

Launched in Q2 2024, this PSU addresses acute supply constraints in the GPU compute market as enterprise adoption of large language models and generative AI workloads intensifies globally. Its specifications reflect current-generation power demands of NVIDIA H100/H200 and AMD MI300X GPU clusters, making it essential infrastructure for organizations scaling AI capabilities.
