G1317-1200WNA – 1200W CRPS Power Supply for Telecom Servers, Edge Computing Nodes, and Distributed Network Equipment
The G1317-1200WNA is a 1200W AC/DC CRPS power module designed for telecom servers, edge computing nodes, and distributed network equipment operating in high-density or space-limited environments. Its compact 1U CRPS-standard form factor (185 × 73.5 × 40 mm) ensures easy integration into modern modular architectures.This model provides a main 54.5V output at 22A along with a 12V standby rail supplying 3A, offering stable and efficient power for POE-driven systems, network processors, and compute hardware at the edge. Designed for infrastructures using a +48Vdc input, it delivers consistent performance across telecom racks, carrier-grade installations, and outdoor/remote nodes. Equipped with PMBus 1.2, the G1317-1200WNA enables detailed telemetry, remote configuration, and automated power optimization. Its high-efficiency design minimizes energy loss and reduces heat generation, improving long-term reliability in tightly packed enclosures. Adaptive fan control ensures efficient thermal management with reduced noise levels, while a reverse-airflow option allows compatibility with diverse cooling layouts used in edge and telecom deployments.

Deployment Scenarios
The G1317-1200WNA is the high-power variant of the G1317 family, delivering 1200W continuous output for deployments where CPU resources operate at high concurrency and GPU acceleration is frequently involved in inference or pre-processing tasks. This capacity tier is ideal for AI inference gateways, mid-range GPU servers, SDS clusters, media processing, multi-tenant virtualization, and regional compute expansion where workloads rise above what 920W can comfortably sustain long-term. With stronger transient handling and wider thermal headroom, the 1200W tier keeps performance stable during real-time model execution, NVMe caching bursts, data aggregation, and traffic-spike scenarios, preventing throttling under peak conditions.

Power Architecture & Reliability Design
The G1317-1200WNA employs an enhanced multi-phase power topology with improved transient recovery, delivering stable 12V output during GPU-accelerated pipelines, caching bursts, and concurrent I/O activity. Its electrical design is optimized to absorb short-term load spikes without rail distortion, supporting inference execution, analytics workloads, and storage commit operations where voltage precision directly affects latency and throughput.
Thermal management is structured around balanced component zoning and controlled airflow paths, reducing localized hotspot pressure even during prolonged compute saturation. Ripple suppression and EMI control protect sensitive PCIe and NVMe fabrics, helping maintain clean signal behavior during storage flush cycles, inference graph input loads, and mixed virtualization traffic that stress both compute and I/O subsystems.
The PSU maintains high efficiency across the duty cycles typical of edge AI deployments, POP resource pools, and hybrid cloud fabrics. Integrated PMBus telemetry enables long-term observation of thermal drift, fan scaling behavior, and load response trends, supporting predictive maintenance strategies in large server fleets. As the upper tier of the G1317 series, the G1317-1200WNA is well suited for environments that require sustained compute capability with predictable electrical and thermal behavior over extended service windows.
