PWS-1K62-BR Supermicro Active 1620W Server PSU

High-Density Redundant Hot-Swap Server Power Architecture with the PWS-1K62-BR

The PWS-1K62-BR is a 1.62kW redundant hot-swap AC PSU module engineered to stabilise modern rack server and GPU server platforms where CPU turbo behaviour, accelerator bursts, and storage spin-up events create rapid load transients. By pairing Titanium-class conversion with active PFC, the PWS-1K62-BR supports predictable power delivery under mixed workloads while reducing upstream power draw and heat output in tightly packed racks.

Designed for enterprise chassis with N+1 or N+N redundancy, the PWS-1K62-BR enables in-service replacement without planned downtime, aligning with 24x7 operational requirements and remote-hands maintenance models. High-efficiency operation helps preserve thermal headroom for PCIe expansion and high-throughput storage backplanes, while the integrated 90mm fan provides directed cooling for sustained high-wattage operation across an operating range of -5°C to 50°C.

Why Choose the PWS-1K62-BR?

The PWS-1K62-BR delivers a balanced density-to-reliability profile for data centre deployments that must maintain node availability during component replacement or PSU failure events. With hot-swap redundancy, high-efficiency Titanium conversion, and controlled power-factor behaviour, the PWS-1K62-BR supports scalable rollouts in compute clusters where consistent electrical characteristics simplify capacity planning and reduce operational risk.

Supermicro designs power subsystems to match enterprise server duty cycles, emphasising platform-level validation, predictable thermals, and serviceability aligned with modern data centre standards. The PWS-1K62-BR follows this engineering approach by integrating redundancy-ready mechanics and efficiency-focused electrical design suitable for continuously operated infrastructure.

Key Applications:

• Redundant power for high-density rack servers
• GPU and accelerator server power domains
• HPC and AI compute clusters
• Enterprise virtualisation hosts
• 24x7 infrastructure requiring hot-swap serviceability
