Nvidia has set out plans to move [AI data centres to an 800-volt direct current (VDC) power architecture](https://blogs.nvidia.com/blog/800-vdc-power-architecture-ai-factory/?ref=ai-360.online), arguing traditional AC-based power distribution cannot keep pace with the density demands of next-generation compute, the company said on 11 August 2026.

Nvidia, Google and [Microsoft](https://www.ai-360.online/microsoft/) have developed the 800 VDC standard together through the Open Compute Project, publishing a joint white paper in March 2026 and a transformer specification in July 2026\. More than 80 equipment and infrastructure companies are now building products to the specification.

For facilities already built around AC infrastructure, Nvidia's MGX-compatible 800 VDC power rack, arriving in the second half of 2026, is designed to slot into existing electrical systems without requiring building-level changes. Nvidia vice president Vladimir Troy said the architecture gives AI factories "a practical path forward, not just a future vision," through the OCP ecosystem.

Nvidia laid out a longer-term roadmap beyond the power rack, including a row power center supporting up to 2 megawatts per rack row, expected in 2027, and a facility-scale DC power block for new builds that converts grid power directly to 800 VDC.

The push comes as Wood Mackenzie projects $9 trillion in global AI and data infrastructure investment through 2040, with Nvidia arguing operators need to resolve power architecture before compute demand outstrips what facilities can deliver.

[AI Contracts Decoded: What Fortune 500 Legal Veterans Know That You Don’tWhen Microsoft refuses to negotiate indemnification with their biggest customers, what does that mean for your AI vendor contracts? When IBM data shows 97% of AI breaches stem from compliance failures—most being supply chain-related—who holds liability?
