China's Envision has switched on what it calls a world-first 800-volt DC power system at the Galaxy AI campus, per TechRadar — a direct shot at one of the AI boom's most stubborn constraints: getting enough clean, efficient power into data centers.

The pitch is straightforward. Conventional data center power chains run through multiple AC/DC conversion stages, each one shedding energy as heat. A high-voltage DC architecture cuts conversion steps, which Envision says yields better efficiency, native support for battery storage, and reduced infrastructure requirements overall.

The move lands as hyperscalers everywhere wrestle with grid bottlenecks, and as the industry converges on higher-voltage DC distribution — Nvidia and its partners have been pushing 800V DC designs for next-generation AI racks. If Envision's deployment performs as claimed, it's a data point that the 800V transition is arriving in production facilities, not just on roadmap slides.
