G1401-2000WNA – 2000W CRPS Power Supply for AI Compute Nodes, Cloud Data Platforms, and High-Density Server Architectures
The G1401-2000WNA is a 2000W Titanium-grade CRPS power supply designed for AI compute nodes, cloud data platforms, and high-density server architectures that require exceptional efficiency and consistent power delivery. Its 1U CRPS-standard chassis (185 × 73.5 × 40 mm) supports streamlined integration into compact, performance-driven systems. Delivering a robust 12V output rated at 166.6A and a 12V standby output at 2.1A, it provides stable power for GPUs, CPUs, storage controllers, and system management modules. The universal input range of 90–264Vac / 180–300Vdc ensures compatibility across global deployments, from hyperscale data centers to distributed compute environments. Digital control and PMBus 1.2 support enable precise power supervision, real-time telemetry, and remote configuration—ideal for automated operations and intelligent workload optimization. Its Titanium-level efficiency helps reduce energy consumption and heat generation during extended high-load operation. The built-in intelligent cooling system adjusts airflow dynamically based on thermal demand, maintaining consistent operating temperatures while minimizing acoustic noise. Optional reverse-airflow support allows flexible placement across various rack orientations, including edge sites and multi-zone data facilities.

Deployment Scenarios
G1401-2000WNA stands as the entry high-power class within the G1401 CRPS platform, designed for data centers that require elevated watt capacity while maintaining strong conversion behavior, thermal predictability and long-life reliability across continuous workloads. This model is well-positioned for virtualization clusters, distributed AI inference nodes, high-volume transaction layers, CDN caching infrastructure, microservice fabric deployments, and medium-to-heavy HPC workloads with day-long runtime windows.
Its watt capacity allows operators to scale node performance without immediate adoption of N+1 rail multiplication, giving infrastructure teams a stable foundation for edge aggregation, database routing, and mid-density GPU-assisted compute. Under distributed workloads where replication, indexing and inference execution overlap across cycles, G1401-2000WNA maintains power discipline with smooth ripple characteristics.

Power Architecture & Reliability Design
The G1401-2000WNA is architected for sustained high-utilization environments where workload pressure, thermal accumulation, and voltage integrity must coexist without sacrificing component longevity. Its switching topology balances conduction efficiency with fast transient recovery, allowing the PSU to maintain stable rails during inference arrivals, data indexing phases, and container surge windows as utilization rises.
Thermal dissipation zones are shaped to distribute airflow evenly across magnetic components and capacitor banks, reducing localized hotspots and slowing electrolyte aging in racks operating near thermal thresholds. Spread-spectrum modulation minimizes EMI signature, improving coexistence with high-speed interconnect fabrics and dense networking environments while preserving clean rail behavior under mixed compute and IO workloads.
PMBus telemetry provides long-horizon operational insight, exposing thermal slope shifts, fan curve elevation, ripple evolution, and accumulated runtime stress patterns. Positioned as the entry performance tier of the G1401 family, the 2000W model delivers safe overhead for sustained load execution, enabling data centers to scale node density confidently before workloads justify a transition into higher-wattage classes for long-term expansion.
