G1401-2200WNA – 2200W CRPS Power Supply for GPU Servers, Scalable Cloud Platforms, and High-Throughput Compute Systems
The G1401-2200WNA is a 2200W CRPS power supply engineered for GPU server platforms, scalable cloud infrastructures, and high-throughput compute systems that require reliable, high-density power delivery. Its 1U CRPS-standard form factor (185 × 73.5 × 40 mm) allows seamless integration into compact, performance-driven environments. This AC/DC unit delivers a regulated 12V output rated at 183.3A together with a 12V standby rail at 2.1A, supporting accelerators, processors, memory subsystems, and system management components. The wide input range of 90–264Vac / 180–300Vdc ensures global deployment flexibility across diverse electrical conditions. Digital power regulation combined with PMBus 1.2 communication enables real-time telemetry, remote adjustments, and accurate monitoring of system power behavior. Its high-efficiency operation helps maintain stable temperatures during intensive workloads, improving long-term reliability. An adaptive cooling system automatically adjusts fan behavior based on thermal demand, ensuring effective heat dissipation while keeping noise output low. Optional reverse-airflow support allows integration into various rack cooling orientations, from traditional data centers to space-restricted compute clusters.

Deployment Scenarios
G1401-2200WNA is the higher-capacity performance tier within the G1401 CRPS platform, designed for environments where distributed compute, analytics indexing, inference serving and cloud-native workloads generate sustained upper-mid utilization ranges beyond what 2000W comfortably covers. This watt class fits deployments where VM concurrency scales, replication windows lengthen, GPU-assisted tasks become routine and data ingestion layers operate continuously throughout the day.
It is frequently adopted in data analytics nodes, inference routing fabrics, large database engines, media transformation clusters, content distribution workloads, hybrid multi-service compute networks, and enterprise-scale virtualization pools. With additional headroom to mitigate load spikes, G1401-2200WNA offers longer performance runway before power ceilings appear, reducing the urgency for immediate multi-PSU parallel introduction.

Power Architecture & Reliability Design
The G1401-2200WNA extends the electrical envelope beyond the 2000W tier to support heavier inference loads, parallel analytics, and blended compute–storage operations without rail degradation at elevated duty levels. Its transient response is tuned for fast recovery when inference batches, container expansion, and database commit phases overlap, while efficiency optimization helps limit thermal overhead during extended high-utilization cycles.
Thermal management is reinforced through widened airflow geometry that stabilizes heat distribution across capacitor banks and magnetic cores, slowing electrolyte fatigue in clusters operating near ambient upper bounds. Spread-spectrum EMI control reduces interference risk in dense interconnect fabrics, preserving signal integrity for high-speed networking and accelerator links as node density increases.
PMBus telemetry delivers multi-metric health visibility, including ripple drift, temperature rise slope, fan curve evolution, and accumulated fault patterns. Positioned as the upper tier of the G1401 family, the 2200W model is recommended for deployments where 2000W configurations approach saturation or where workload growth forecasts require additional headroom without immediate transition to higher-wattage platforms.
