Technical specifications for AI data center infrastructure indicate that Nvidia 800V rack designs require approximately 200 tons of copper per gigawatt of power demand specifically for busbars.

Context

Nvidia is aggressively pivoting toward co-packaged optics (CPO) and 800V HVDC power architectures to mitigate the unsustainable material demands of next-generation AI factories. With copper demand projected to grow at 6% annually through 2030, supply constraints have forced a shift away from traditional copper-heavy interconnects. Industry estimates for data center copper intensity vary significantly, ranging from BHP’s low of 27,000 tons per GW to Schneider Electric’s high of 65,000 tons per GW. By transitioning to "all fiber" networking, Nvidia aims to reduce copper requirements by approximately 5,000 tons per GW. The technical shift begins with the Quantum-X and Spectrum-X photonics platforms, slated for commercial rollout in 2025 and 2026. This evolution is paired with a move to 800V DC power standards by 2027, which uses higher voltage to slash the volume of heavy copper busbars required for power distribution. These innovations are critical for scaling to million-GPU clusters while avoiding a looming bottleneck in global metal markets.
