PWS-2K21G-2R
High-Density 2U Redundant Hot-Swap Power Module featuring PMBus Monitoring with the PWS-2K21G-2R
The PWS-2K21G-2R is a 2200W AC hot-swap PSU module engineered for Supermicro 2U redundant-capable chassis where modern CPU and GPU configurations drive fast load transients and sustained peak draw. By pairing high conversion efficiency (80 PLUS Titanium/Platinum) with deterministic power delivery, the PWS-2K21G-2R supports stable operation in GPU/AI nodes, virtualization hosts, and storage platforms that cannot tolerate brownouts during accelerator ramp or storage rebuild events.
Designed for serviceable rack architectures, the PWS-2K21G-2R integrates PMBus 1.2 for telemetry and control, enabling platform-level power budgeting, health monitoring, and automated alerting through BMC tooling. Protection coverage including OCP, OVP, and SCP helps isolate electrical faults before they cascade into downstream components, while the redundant hot-swap model enables replacement without planned downtime. This aligns power architecture with PCIe-attached expansion and high I/O storage layouts by maintaining consistent rail stability under mixed compute and I/O bursts.
Why Choose the PWS-2K21G-2R?
The PWS-2K21G-2R delivers a strong density-to-power ratio for 2U deployments that consolidate GPUs, high-core-count CPUs, and NVMe-heavy storage, while preserving availability through true hot-swap redundancy. With PMBus visibility and enterprise protection features, the PWS-2K21G-2R simplifies capacity planning, reduces operational risk, and scales cleanly across standardized chassis fleets in production racks.
Supermicro designs power subsystems to match data centre serviceability expectations, emphasizing validated interoperability, predictable thermal and electrical behavior, and long-life components suited for continuous duty cycles. The PWS-2K21G-2R reflects this approach with monitoring-centric engineering and deployment alignment to modern rack management standards.
Key Applications:
- 2U GPU/AI compute servers
- High-density virtualization hosts
- NVMe storage and SDS nodes
- Redundant PSU replacement and spares
At Happyware - Server Hardware you benefit from non-binding offers tailored to your chassis and redundancy design, helping you source the correct PWS-2K21G-2R configuration with minimal procurement risk. For fleet rollouts, bulk order discount options support standardized power modules across multiple racks and sites.
