TrendForce’s latest AI server power‑architecture study says NVIDIA is developing
an 800V HVDC Power Rack, targeting inventory readiness in Q3 2026 and offering
it as an optional (non‑standard) configuration for Vera Rubin customers. Based
on per‑cabinet power designs, adoption should expand after the Rubin Ultra
series in H2 2027, with large-scale deployment estimated in 2028.
