NVIDIA developing 800V HVDC Power Rack for Vera Rubin (next-gen cluster), targeting Q3 2026 readiness with full-scale adoption expected 2028+.

NVIDIA is developing an 800V HVDC Power Rack to support its Vera Rubin next-generation cluster, according to TrendForce analysis of AI server power architectures. The company targets completion of the rack design by Q3 2026, with availability as an optional offering for Vera Rubin customers—not as a standard configuration.

Broader adoption is expected to accelerate after the Rubin Ultra series launches in late 2027, when the 800V Power Rack design becomes increasingly incorporated into cabinet deployments. Full-scale adoption across NVIDIA's infrastructure is estimated to arrive in 2028 and beyond.

The transition to 800V HVDC power delivery signals NVIDIA's push toward higher-voltage, more efficient power distribution for next-generation AI clusters. Higher voltages reduce current flow and associated losses, allowing denser compute packaging and lower infrastructure costs—key advantages as GPU clusters scale to handle larger training and inference workloads.
