2025 OCP APAC Summit

This presentation outlines the evolving requirements and technical considerations for next-generation Open Rack V3 (ORv3) Power Supply Units (PSUs) and power shelves, with a focus on the transition from ORv3 to High Power Rack (HPR) and HPR2 architectures. It highlights significant advancements such as increased power density from 33kW to 72kW, enhanced support for AI-driven pulse load demand. HVDC architecture is also introduced for quick adaptation to solve the challenging of bus bar while power demand from AI still keeps on increasing.
