PWS-2K03P-1R Supermicro Active 2000W 1U PSU

High-Density 1U Redundant Hot-Swap Server PSU Module with the PWS-2K03P-1R

The PWS-2K03P-1R is a 1U redundant hot-swap power supply module engineered for Supermicro rack platforms that require continuous uptime under variable compute and storage loads. With 2000W capacity and 80 PLUS Platinum efficiency, it supports modern CPU and GPU server configurations by reducing conversion losses and thermals, improving rack-level power budgeting and cooling stability.

Designed for enterprise power domains, the PWS-2K03P-1R integrates PMBus 1.2 telemetry for power monitoring and policy-driven management, enabling tighter control in automated data centre operations. Active PFC improves input power quality, while protection mechanisms such as OVP, OCP, and SCP help maintain system integrity during fault conditions. The hot-swap architecture aligns with serviceability targets in high-density environments, allowing PSU replacement cycles without planned downtime when deployed in redundant configurations.

Why Choose the PWS-2K03P-1R?

The PWS-2K03P-1R provides a strong density-to-resilience profile for 1U server nodes where power headroom and availability are critical. Its redundant, hot-swappable design supports scalable fleet operations by standardising maintenance procedures and minimising MTTR, while the Platinum efficiency profile helps sustain predictable performance within constrained rack power envelopes. The PWS-2K03P-1R is a pragmatic choice for deployments that prioritise operational continuity and manageable power observability.

Supermicro designs power subsystems with a focus on data centre reliability, compliance, and platform integration, aligning PSU behaviour with enterprise rack standards and service workflows. The PWS-2K03P-1R reflects this approach through controlled power management interfaces and robust protection for mission-critical infrastructure.

Key Applications:

• 1U rack server power redundancy
• High-density compute nodes
• Storage and NVMe-heavy platforms
