G1505-2700WNA – 2700W CRPS Power Supply for Advanced AI Servers, High-Density Compute Racks, and Large-Scale Cloud Systems
The G1505-2700WNA is a 2700W CRPS power supply designed for advanced AI servers, high-density compute racks, and large-scale cloud systems requiring exceptionally stable and high-capacity power delivery. Its 1U CRPS-standard footprint (185 × 73.5 × 40 mm) enables efficient integration into compact data center environments. This module provides a robust 12V main output rated at 225A, supported by a 12V standby rail at 2.1A for system monitoring, management controllers, and auxiliary electronics. The universal input voltage range of 90–264Vac / 180–300Vdc allows deployment across global compute facilities with varying power infrastructures. Featuring digital regulation and PMBus 1.2 support, the G1505-2700WNA delivers precise telemetry, remote configuration, and intelligent control of critical power parameters—ideal for automated AI clusters and orchestrated compute environments. Its efficient operating profile helps maintain thermal stability even under sustained high-load cycles. An adaptive cooling system ensures consistent airflow by dynamically adjusting fan speed according to system temperature and workload. Optional reverse-airflow capability provides flexibility for different rack orientations, making the unit suitable for both traditional and inverted cooling paths in dense compute deployments.

Deployment Scenarios
G1505-2700WNA sits as the entry topology within the G1505 high-density platform, designed for mid-to-high performance compute farms where sustained power draw, accelerator burst load and distributed concurrency run above the comfort zone of 2KW-class units. This watt tier is suited for GPU inference clusters, parallel virtualization nodes, large multi-tenant SaaS infrastructure, DB replication rings, analytics consolidation layers and multi-service data center racks moving toward higher utilization density.
Teams frequently deploy G1505-2700WNA in micro-HPC corridors, orchestration gateways, scalable storage-backed fabrics, medium GPU inference deployment rings, CDN and caching layers, media encoding pipelines and hybrid CPU+GPU compute grids. It provides thermal predictability, transient absorption capacity and ripple stability under concurrency events, making it a reliable baseline for heavy workloads without immediately stepping into extreme watt categories.

Power Architecture & Reliability Design
The G1505-2700WNA is engineered for heavy-duty compute environments where accelerated workloads operate for extended intervals, demanding conduction efficiency, rail stability, and ripple moderation as utilization approaches saturation. Its conversion stages preserve waveform integrity through inference bursts, database commit waves, container spool-up events, and analytics indexing cycles, allowing sustained high-duty operation without voltage degradation.
Thermal routing is designed to distribute airflow evenly across switching elements and magnetic components, reducing localized heat concentration and extending capacitor lifetime during long uptime windows. Spread-spectrum EMI shaping limits signal interference within dense backplane and interconnect fabrics, supporting clean coexistence with high-bandwidth networking and accelerator links under elevated load conditions.
PMBus-based health visibility enables early detection of degradation through trend analysis, including ripple ascent, thermal slope behavior, fan duty profile drift, and event frequency accumulation. Positioned as a strategic entry tier below extreme-watt platforms, the G1505-2700WNA supports high-density deployment growth while delaying the transition to 3200W-class solutions for continuous AI acceleration or HPC saturation scenarios.
