### @power-semis — Estimate — architecture per NVIDIA disclosures; content-expansion per industry research
AI racks pushing toward 600 kW hit copper-thickness and loss limits at lower voltages, so NVIDIA is driving an 800 V DC architecture for its 2027 rack generation with conversion moving closer to the chips. The per-rack power-chip content expands — but the research insists the dated transition isn't a business result. Five companies claim the tailwind with five different structural positions; value capture is demonstrably asymmetric.
