PWS-1K11P-1R Supermicro Active 1010W 1U Server PSU

High-Performance 1U Server Power Supply Module with PMBus Telemetry using the PWS-1K11P-1R

The PWS-1K11P-1R is a 1U AC-DC power module engineered for Supermicro rack server platforms where predictable power delivery and serviceable spares strategy are mandatory. With 1010W output, active PFC, and up to 90% peak efficiency, the design supports stable rails under variable CPU and PCIe load profiles, helping maintain platform power margins for dense configurations and mixed I/O expansion.

For operational control, the PWS-1K11P-1R implements digital monitoring and control with PMBus 1.1, enabling PSU-level telemetry in environments that rely on automated health checks and proactive maintenance windows. Integration is streamlined via a 24-pin ATX main connector with a detachable 4-pin section, while OCP, OVP, and SCP protections reduce the risk of component stress during transient events. The PWS-1K11P-1R is also suitable for system-dependent redundant-capable power infrastructures, supporting continuity planning when paired in compatible chassis configurations.

Why Choose the PWS-1K11P-1R?

The PWS-1K11P-1R delivers a balanced density-to-power profile for 1U deployments where monitored power is part of the operational baseline. It aligns with enterprise reliability requirements by combining efficiency, protection circuitry, and PMBus-managed visibility, and it scales cleanly as a standardized replacement module across fleets to reduce variance in spares and maintenance processes.

Supermicro power engineering emphasizes platform consistency, serviceability, and compliance with modern data centre integration practices, enabling predictable behavior across supported server generations and simplifying lifecycle management within standardized rack environments.

Key Applications:

• Rack server PSU replacement and spares
• Monitored power telemetry for fleet operations
• Redundant-capable power configurations (system-dependent)
• Data centre standardization and lifecycle refresh
