Powering next-generation AI infrastructure with 110 kW DC power delivery

Flex’s 110 kW 3RU MGX power shelf for NVIDIA Vera Rubin NVL72 (or equivalent) is designed for the most demanding GPU workloads. Supporting up to six hot-pluggable 18.4 kW power supply units (PSUs) and one power supply controller (PSC), the shelf delivers up to 110 kW of DC output power to all rack-level payloads through a 52 V DC-DC bus architecture, operating with a three-phase AC input range of 346 VAC to 480 VAC.

主要特点

  • Hot-pluggable PSUs and PSC for simplified servicing and zero-downtime maintenance
  • Telemetry and monitoring available through Redfish for real-time visibility into shelf and PSU health
  • Current sharing capability across multiple shelves with two rear-side RJ45 connectors enabling synchronized power-up and active current sharing
NVIDIA Vera Rubin NVL72 电源架
  • Bootloader support for field firmware upgrades of both PSC and PSUs, upgradable online by the system
  • Front-to-back airflow with internally controlled variable-speed fans
  • Power pulsation buffer device (>1200J energy storage) ensures sinusoidal AC input current under dynamic and EDPP loading conditions
  • Titanium+ efficiency at 400 VAC, 415 VAC, and 480 VAC (measured with fans)
  • UL/IEC62368-1 safety certified
