Flex announced a new power shelf system to fast-track 800 VDC power architectures and support the growing demands of AI infrastructure, AI factories, and data centers.
The Flex power shelf system provides industry-leading efficiency for NVIDIA GB300 NVL72 systems while preparing for the transition to 800 VDC data center power infrastructure to support the deployment of 1 megawatt IT racks, the company said.
“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,” said Chris Butler, president, critical and embedded power at Flex. “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.”
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, it achieves peak efficiency of 97.5 percent at half-load. This reduces power conversion losses by more than 60 percent compared to conventional systems, 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.
Flex’s new power shelf delivers high-efficiency power tailored for the NVIDIA GB300 NVL72 rack-scale platform—providing a robust foundation 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 for the NVIDIA GB300 NVL72 joins Flex’s robust portfolio of grid-to-chip power products. Flex provides advanced manufacturing capabilities, innovative power and cooling products, and end-to-end lifecycle services that solve data center power, heat, and scale challenges in the AI era.
