As AI factory compute density accelerates toward the megawatt scale, traditional AC power supply has become a core bottleneck for compute expansion. Reaching an industry consensus, NVIDIA—together with supply chain partners including Google and Microsoft—has established 800VDC as the standard power supply path for next-generation, high-density AI infrastructure, officially transitioning the industry from technical validation to full-scale deployment.

The white paper systematically outlines three deployment architectures—rack-level, cluster-level, and hall-level—supporting a smooth transition mode where AC and DC coexist to accommodate varying scales of facility retrofits and new builds.

Furthermore, it establishes a layered safety architecture centered around grounding design, arc fault protection, and solid-state circuit breakers (SSCBs). By concurrently advancing the equipment ecosystem, certification standards, and pilot deployments, it provides a complete power architecture solution for scaling compute capacity in AI factories.
