World’s first? Nvidia has had a three-phase architecture of 800V DC adoption in their specs for over a year. I am having difficulty believing that nobody else has implemented this.

    I was confused too, and the article didn't make it very clear, but from what I gather, the world-first part is the solid-state-transformer that converts 10kV AC directly to 800V DC instead of some multi-stage setup (hence the advertised gains)

    AWS has been doing this for over a decade now as I've heard each racks gets 800v DC. Hungry GPUs have gotten more attention for others. Datacenters next plan is to put 1500v at rack level.
