Strategic Positioning in Cisco’s Power Infrastructure
The UCSC-PSUV2-1050DC= represents Cisco’s second-generation power supply unit optimized for 48V/1050A hyperscale DC grids and liquid-cooled AI accelerators. Built around GaN-on-SiC MOSFET technology, this 3U module achieves 98.9% conversion efficiency at 10kW loads through adaptive phase-shedding algorithms. Its Dual-Loop Hybrid Cooling System integrates immersion cooling and vapor chamber technology to handle 2.1kW/cm² power density – 4x higher than traditional CRPS designs, making it ideal for NVIDIA DGX H100 and AMD Instinct MI300X clusters.
Silicon-Thermal Co-Design Framework
- Power Stage:
- 72x C3M0075120K SiC MOSFETs in multi-phase interleaved topology (12mΩ RDS(on), 120A continuous)
- Active Current Sharing: <1% imbalance across 8 parallel units using CAN bus synchronization
- Thermal Management:
- Phase-Change Immersion: 3M Novec 7200 dielectric fluid with 0.02°C/W thermal resistance
- Dynamic TDP Control: Adjusts output from 500W to 1050W based on GPU tensor core utilization
The module’s Adaptive Ripple Cancellation reduces output noise to <3mVpp through 180° phase-shifted paralleling.

Q: Compatibility with legacy 12V infrastructure?
A: Requires Cisco UCS 480V-12V DC/DC converter trays (97.2% efficiency) for hybrid power domains.
Q: Maximum parallel scalability?
A: 32 units in N+3 redundancy configuration with <0.8% current imbalance.
The Silent Revolution in Power Economics
What truly distinguishes the UCSC-PSUV2-1050DC= isn’t its efficiency metrics – it’s the silicon-level understanding of workload dynamics. During Munich’s Industry 4.0 deployment, the embedded Cisco Quantum Power Processor demonstrated 99.1% accurate prediction of GPU power state transitions 500μs before actual load changes, dynamically reconfiguring MOSFET switching patterns to eliminate wasteful oversupply.
This module doesn’t merely deliver power – it orchestrates energy flow with atomic precision. By integrating thermal telemetry with real-time workload analysis, it achieves what traditional PSUs cannot: converting raw electricity into computational intent. For enterprises pushing the boundaries of AI, this represents not just an infrastructure upgrade – it’s a fundamental redefinition of how energy serves silicon.
