Flex provides power management systems optimized for next-generation NVIDIA AI infrastructure.

On August 4, 2025, Flex (NASDAQ: FLEX) announced a new power shelf system designed to accelerate 800 VDC power architectures and meet the growing demands of AI infrastructure and AI factories. The system provides industry-leading efficiency for NVIDIA GB300 NVL72 platforms while preparing for the transition to 800 VDC data center power infrastructure to support 1 megawatt IT racks. Chris Butler, president of Critical and Embedded Power at Flex, stated: "As AI workloads push rack power systems to new levels, Flex is at the forefront of enabling data center operators to overcome increasing power, heat, and scale challenges. Our collaboration with NVIDIA enables hyperscale and colocation customers to deploy next-generation AI infrastructure with greater speed and efficiency as they scale toward 1 MW racks and 800 VDC data center power infrastructure."

Introduced at OCP APAC, the Flex power shelf system is a high-density DC power distribution solution delivering up to 33 kW per shelf in a compact, industry-standard footprint. Featuring six power supply units in a 3+3 redundant configuration and an advanced power shelf controller, the system achieves peak efficiency of 97.5 percent at half-load. This design reduces power conversion losses by more than 60 percent compared to conventional systems, thereby lowering heat output, cooling demands, and energy costs. Fully compatible with the NVIDIA GB300 NVL72 platform that features 72 NVIDIA Blackwell Ultra GPUs, the system supports high-performance GPU- and CPU-based workloads for AI factories.

The power shelf delivers high-efficiency power tailored for the NVIDIA GB300 NVL72 rack-scale platform, providing a robust foundation today while paving the way for 800 VDC data center power infrastructure. Flex plans full-scale production of 800 VDC power components to coincide with the release of NVIDIA Kyber rack-scale systems, ensuring seamless scalability for increasingly demanding AI models. The power shelf system joins Flex's broader portfolio of grid-to-chip power products, complementing the company's advanced manufacturing capabilities, innovative power and cooling products, and end-to-end lifecycle services that address data center power, heat, and scale challenges in the AI era.
