PWS-1K66P-1R
High-Density 1U Redundant Hot-Swap Power Module for resilient rack power with the PWS-1K66P-1R
The PWS-1K66P-1R is a 1U redundant 1600W hot-swap power supply module designed to maintain continuous server operation during PSU replacement or failure in Supermicro 1U chassis power bays. Rather than influencing CPU or GPU compute directly, the PWS-1K66P-1R stabilises the electrical foundation those platforms depend on, delivering consistent power delivery for modern multi-core CPU nodes, storage-dense systems, and accelerator-capable configurations where uptime and predictable power margins are critical.
Built for high-efficiency rack power architecture, the PWS-1K66P-1R supports 80 PLUS Platinum efficiency to reduce wasted energy and heat load at the rack level, improving thermal headroom for memory and PCIe expansion subsystems. PMBus 1.2 telemetry enables firmware and BMC-level monitoring for proactive maintenance, while the hot-swap design aligns with serviceability requirements in production environments. A wide operating window of 0–50°C and integrated protections (OCP, OVP, UVP, SCP, OTP) help keep power stable across fluctuating data centre conditions and transient load events.
Why Choose the PWS-1K66P-1R?
The PWS-1K66P-1R delivers enterprise-grade redundancy in a compact 1U form factor, optimising density-to-availability for racks where maintenance windows are limited. With monitored power behaviour via PMBus and robust protection logic, the PWS-1K66P-1R supports scalable fleet operations, enabling consistent deployment standards and reducing risk during in-service replacement.
Supermicro engineers server power subsystems for predictable interoperability, focusing on validated chassis integration, compliance-ready design, and operational reliability aligned with modern data centre requirements, including EMI Class A and safety standards such as UL/IEC 60950-1.
Key Applications:
- Redundant PSU replacement and lifecycle maintenance
- 1U rack server uptime and failover continuity
- Power monitoring and telemetry-driven operations
- Energy-efficient data centre power architecture
