to 800V, which cuts amperage by ~15x and tames the so-called “copper tax,” albeit manmohanpreet.singh@jpmchase.com

at the cost of introducing new technologies. While the destination is broadly agreed Marc Vitenzon

upon, the journey is likely to unfold in phases, with architectural approaches (1-212) 622-3342

differing simplistically in where AC-to-DC conversion occurs, with some more marc.vitenzon@jpmchase.com

others are better suited in the long-term as power densities inflect higher. The

directional shift is nonetheless clear, and is already shaking up the supplier

landscape from silicon to substation in order to prepare for data center IT loads that

are on track to triple to ~300 GW by 2030, and dollar content scaling even faster,
