Texas Instruments and NVIDIA Collaborate on 800V High-Voltage DC Power Systems for AI Data Centers
Texas Instruments (TI) has partnered with NVIDIA to develop advanced power management and sensing technologies for 800V high-voltage direct current (HVDC) power distribution systems. This collaboration aims to create the infrastructure necessary to meet the growing demands of AI data centers.
The new power architecture will be crucial in enabling the scalability and reliability required for next-generation AI-powered systems.
Why This Development Is Crucial
As AI technology advances, the power requirements for data center servers will rise considerably. Presently, every data center rack draws roughly 100kW of power.
Nonetheless, projections indicate that this figure will increase to more than 1MW per rack soon. Traditional 48V power systems, which would require almost 450lbs of copper to support such demands, are simply not scalable for the long-term requirements of AI workloads.
In contrast, the new 800V high-voltage DC power-distribution architecture promises to deliver the necessary power density and conversion efficiency to support future AI processors. By minimizing the weight, volume, and complexity of power supplies, the architecture enables more power-efficient racks that can scale in accordance with changing data center needs.

A Paradigm Shift for AI Infrastructure
Jeffrey Morroni, Director of Power Management Research and Development at TI’s Kilby Labs, said, “A paradigm shift is happening right in front of our eyes.”
He added, “AI data centers are pushing the limits of power to previously unimaginable levels. A few years ago, we faced 48V infrastructures as the next big challenge. Today, TI’s expertise in power conversion combined with NVIDIA's AI expertise is enabling 800V high-voltage DC architectures to support the unprecedented demand for AI computing.”
Gabriele Gorla, VP of System Engineering at NVIDIA, also highlighted the critical role of semiconductor power systems in enabling high-performance AI infrastructure. With this new architecture, the collaboration between NVIDIA and TI aims to set a foundation for supporting large-scale, next-generation AI data centers efficiently.
