Understanding High-Voltage DC Power Architectures for AI
By 2027, NVIDIA''s Kyber system is projected to demand 600 kW per rack with the Vera Rubin Ultra series of chips, an order of magnitude increase over CPU data centers from five years

Microsoft and Meta have been working on a new open rack design for AI data centers which separates power and compute into different cabinets. Known as Mount Diablo,
At the 2025 OCP EMEA Summit today, we discussed the power delivery transformation from 48 volts direct current (VDC) to the new +/-400 VDC, which will enable IT
High-density power modules with low thermal resistance and coplanar surfaces for straightforward mating to liquid-cooling cold plates will play a key role in enabling high-voltage DC distribution
Traditionally, data centers distribute three-phase 415/480V AC directly to each compute rack, where it is converted to 48V DC. In the proposed model, racks receive ±400V.
This presentation will discuss how we arrive at the design choice- including: 1) Power demand roadmap- 2) input power to rack- 3) rack DC distribution & safety)- 4) considerations for
400V DC power is designed to ensure the highest levels of eficiency and reliability. Based on a flexible architecture, 400V DC power can be implemented at a wide variety of diferent telecom
Based on a flexible architecture, 400V HVDC power can be implemented at a wide variety of telecom and data centers sites. Whether your site equipment powering needs include 400
