The Need for Power Innovation

As AI chips become increasingly powerful, they require more electricity, causing existing power systems to struggle. NVIDIA reports that the current 54V DC power distribution system is reaching its capacity as racks begin to exceed 200 kilowatts. The company predicts that power requirements per data center rack will surge from 100kW today to more than 1MW in the near future 3

. These collaborations aim to create robust and diverse power solutions to meet NVIDIA's goals.

The implementation of the new power system will occur in phases:

1. Initially, power supply units (PSUs) will be placed beside the rack in a "sidecar" configuration.
2. Over time, NVIDIA plans to integrate these power modules into a centralized power delivery system for entire AI data centers 2
