Vicor Corporation — AI supply-chain exposure

Vicor designs high-density power modules and the factorized power architecture used to deliver electricity to AI accelerators and high-performance processors at the point of load. It sits in the power-delivery layer between the rack and the chip: modern accelerators draw enormous current at very low voltage, and getting that power the last few centimetres — cleanly, efficiently, without wasting it as heat — is a specialised engineering problem its modules address.

The structural hook is that as accelerator power keeps climbing, power delivery has become a genuine design constraint rather than an afterthought. Converting rack voltage down close to the die frees board space and cuts losses, which matters more with every generation of hotter chips. Vicor's factorized approach is a differentiated position in a niche that scales directly with accelerator power draw — a small but increasingly binding link as the silicon it feeds grows more demanding.
