PWS-2K63A-1R Supermicro Active 2600W 1U Server PSU

High-Density 1U Redundant Hot-Swap Power Supply Architecture with the PWS-2K63A-1R

The PWS-2K63A-1R is a 1U redundant hot-swap PSU module engineered for high-density rack servers where GPU acceleration, high-core-count CPUs, and power-intensive storage require stable delivery under sustained load. With 2600W capacity and 80 PLUS Titanium efficiency, the PWS-2K63A-1R supports power budgets that align with modern PCIe expansion and multiple accelerator-class devices while minimizing conversion losses and thermal impact at the rack level.

Designed for enterprise platforms that demand continuous operation, the PWS-2K63A-1R integrates PMBus v1.2 telemetry to expose power, voltage, current, and status data for infrastructure monitoring and automated management. Protection mechanisms including OCP, OVP, and SCP help isolate fault conditions, supporting predictable behavior during transient spikes common in GPU nodes and high-throughput storage controllers. In redundant configurations, the hot-swap design enables service actions without interrupting workloads, improving overall availability.

Why Choose the PWS-2K63A-1R?

The PWS-2K63A-1R provides a strong density-to-performance ratio for 1U deployments by combining high wattage with Titanium-class efficiency and operational telemetry, enabling tighter rack power planning and more consistent thermal envelopes. Its redundant hot-swap profile supports scalable rollouts across compute clusters, storage tiers, and accelerator pods where maintenance windows are limited and uptime objectives are strict.

Supermicro designs power subsystems with a focus on data centre reliability, serviceability, and standards alignment, ensuring that modules such as the PWS-2K63A-1R integrate cleanly into enterprise racks with controlled power behavior, compliance readiness, and predictable lifecycle management.
