Flex announced an 800 VDC Power Rack developed in collaboration with NVIDIA to support the NVIDIA Vera Rubin platform, targeting higher-efficiency power delivery for next-generation AI infrastructure. Flex positions the rack as part of its AI Infrastructure Platform and says it’s built to accelerate deployment of 800 VDC architectures at global scale.

In the release, Flex argues that traditional in-rack power distribution systems designed for kilowatt-scale racks “can no longer support the megawatt-scale demands” of modern AI workloads. Flex also points to NVIDIA’s 800 VDC architecture announcement as a “new benchmark for AI infrastructure,” framing the new rack as an enabling building block for that shift.

Technically, Flex says the 800 VDC Power Rack uses a disaggregated architecture and includes Flex’s power shelf for the NVIDIA Vera Rubin platform. The company describes the approach as shifting power products out of the IT rack to free up space for compute, with the stated goal of packing GPUs more densely and improving communication efficiency.

Flex claims the architecture can help “current data centers” support high power density, next-generation accelerated computing racks without “costly retrofits.” It also provides a before-and-after power-density number: “When deployed with a future GPU platform,” Flex says the approach can increase available compute power per rack from approximately 125 kW to up to 880 kW.

For ride-through and resiliency, Flex says it also offers Battery Backup Units (BBUs) and Capacitor Backup Units (CBUs) as options for the 800 VDC Power Rack, “protecting critical AI workloads from outages and grid disturbances.” The announcement doesn’t include electrical interface details (for example, input feed requirements, conversion stages, protection, or rack-level distribution topology) beyond the 800 VDC architecture callout and the disaggregated design description.

Flex is also selling its manufacturing story alongside the product. The company says the 800 VDC Power Rack is supported by Flex’s global manufacturing and supply chain network, including “the ability to manufacture the 800 VDC Power Rack in North America,” which it frames as giving customers in-region manufacturing flexibility.

“Megawatt-scale AI workloads are redefining what’s required from data center power infrastructure,” said Chris Butler, President, Embedded and Critical Power, Flex. “Flex’s 800 VDC Power Rack pairs advanced power products with global manufacturing scale to enable efficient, scalable power delivery and faster deployment of next-generation infrastructure.”
