Company collaborates with Nvidia on power systems for AI racks consuming up to 1.2MW

Schneider Electric on Aug. 4 outlined its progress in developing 800-volt direct current (800V DC) power infrastructure for artificial intelligence data centers, as it works with Nvidia to support next-generation AI racks with power requirements of up to 1.2 megawatts (MW).
Rising demand for generative AI and high-performance computing is driving data center rack power densities beyond 400 kilowatts (kW) and toward the megawatt range. Conventional alternating current (AC)-based power architectures increasingly face limitations because power conversion equipment, cables and connectors occupy valuable space inside IT racks, restricting compute density and airflow while increasing cooling requirements.
The 800V DC approach reduces current levels by operating at higher voltage, enabling efficient delivery of megawatt-scale power. By relocating AC-to-DC conversion equipment outside the IT rack, operators can free up space for GPUs and servers while improving airflow, power delivery efficiency and cooling performance.
Schneider Electric said it is developing an architecture that introduces 800V DC technology into existing data center environments through the use of dedicated power racks positioned alongside IT racks. These power racks handle power conversion and protection functions. The modular design also helps contain failures within individual racks, reducing the scope of potential disruptions.
The company is working with Nvidia on an 800V DC “sidecar” power system capable of supplying up to 1.2MW to next-generation AI racks. At Nvidia GTC earlier this year, Schneider Electric demonstrated a prototype 800V DC power infrastructure designed for Nvidia’s Vera Rubin Ultra platform.
Schneider Electric said its approach extends beyond power conversion equipment to include integrated design of grounding and protection systems, energy storage solutions and upstream and downstream power infrastructure. The company also conducts fault-current and arc-flash analysis, power system modeling, simulation and validation in real-world testing environments.
“Transitioning to 800V DC is not simply a matter of increasing voltage,” Kwon Ji-woong, country president of Schneider Electric Korea, said in a statement. “It requires designing and validating power conversion, protection, energy storage and maintenance as a unified system. We will support customers in implementing 800V DC architectures tailored to their operational environments.”
