Rack Level Infrastructure: Power Delivery

In the GB200 article from 2024 , we discussed the previous evolution on power delivery from node level PSU (power supply unit) to centralized rack level power shelf. As VR NVL72 rack TDP reaches 180kW-220kW per rack from 120kW-140kW for GB200 and GB300, the power delivery infrastructure has evolved yet again. In the section below we will discuss the power delivery infrastructure at the rack level of the reference design and the power delivery at the compute tray level for VR NVL72.

Evidence

Hyperscalers are developing power delivery infrastructure to address the challenges that comes with high density AI server racks with the roadmap set to 1MW per rack in the next couple of years
