Texas Instruments and NVIDIA partner on 800V power distribution for AI data centers

Texas Instruments (TI) has announced a collaboration with NVIDIA to develop power management and sensing technologies for 800V high-voltage direct current (HVDC) power distribution systems for data center servers, aimed at supporting scalable and reliable next-generation AI data centers.
The power demand per data center rack is projected to increase from 100kW to over 1MW in the near future. Current 48V distribution systems would require approximately 450 pounds of copper to support a 1MW rack, limiting their ability to scale for long-term computing needs. The 800V HVDC architecture is designed to provide the power density and conversion efficiency needed for future AI processors while minimizing increases in power supply size, weight, and complexity.
Jeffrey Morroni, director of power management research and development at TI’s Kilby Labs, stated that the partnership leverages TI’s power conversion expertise and NVIDIA’s AI expertise to address the rising power demands of AI data centers, transitioning from 48V to 800V architectures. Gabriele Gorla, NVIDIA’s vice president of system engineering, noted that the 800V HVDC architecture will support the power requirements of large-scale AI data centers.
