PWS-1K02A-1R Supermicro 1000W 1U PSU

High-Efficiency 1U CRPS Redundant Hot-Swap Power Module with the PWS-1K02A-1R

The PWS-1K02A-1R is a 1000W single-output 1U CRPS power supply module engineered for redundant power bays in modern rack servers, where predictable power delivery and serviceability are operational requirements. Designed for hot-swap maintenance, the PWS-1K02A-1R supports live replacement workflows that reduce downtime during refresh cycles and capacity expansions in enterprise racks.

With an 80 PLUS Titanium efficiency profile, the PWS-1K02A-1R targets lower conversion losses under sustained load, supporting thermal headroom and consistent chassis airflow design. PMBus 1.2 integration enables platform-level telemetry and power management, allowing monitoring systems to correlate power behavior with CPU, memory, PCIe, and storage activity for fault isolation and capacity planning. Protection functions including OCP, OVP, UVP, SCP, and OTP are implemented to help safeguard server backplanes and attached compute nodes, while a 0–50°C operating envelope aligns with controlled data centre environments and standard front-to-back airflow architectures.

Why Choose the PWS-1K02A-1R?

The PWS-1K02A-1R delivers a practical density-to-reliability balance for 1U CRPS platforms by combining hot-swap redundancy behavior with high-efficiency conversion and PMBus visibility. For enterprise operations teams, the PWS-1K02A-1R supports standardized spares strategy, faster mean-time-to-repair, and consistent power bay compatibility across server fleets, making it well suited to phased infrastructure refresh and scalable rack deployments.

Supermicro designs power subsystems to match enterprise chassis requirements, prioritizing electrical stability, protection coverage, and telemetry-ready integration that aligns with modern data centre monitoring, compliance, and lifecycle management practices.

Key Applications:

• 1U server power bay redundancy
• Data centre PSU standardization programs
• Hot-swap maintenance operations
• PMBus-based power telemetry monitoring
