Flex unveils NVIDIA-aligned AI factory designs with 800 VDC power and liquid cooling for hyperscale data centers

Flex announced new NVIDIA Omniverse DSX Blueprint reference designs on 16 March 2026, offering prefabricated, modular power and liquid-cooling systems for AI data centres. The systems feature an 800 VDC Power Rack and support phased migration from traditional AC setups, positioning Flex as a systems-level partner for hyperscale AI infrastructure rather than a traditional contract manufacturer. The announcement follows Flex's expanded collaboration with AMD to build Instinct AI platforms in Austin. Together, these moves underscore Flex's strategy to become a full-stack AI hardware and infrastructure partner, though customer concentration and potential in-housing of power and cooling capabilities remain key risks. Optimistic analysts project Flex reaching $29.7 billion revenue and $1.4 billion earnings by 2028. The company's shares rose 5.1% following the announcement.
