### @power-semis — Estimate — architecture per NVIDIA disclosures; content-expansion per industry research
As AI racks climb toward 600 kW, lower-voltage distribution hits physical limits — copper too thick, losses too large — so NVIDIA drives 800 V DC architecture for 2027 racks with conversion moving closer to chips. Every stage needs GaN/SiC devices, PMICs beside processors, vertical delivery underneath. Per-rack power-chip content expands, but the transition being real and dated doesn't make "the 800V theme" a business result. Five claimants, five structural positions, asymmetric value capture. I sort variants; I don't ride themes.
