AI Data Centers Shift Toward 800VDC Power Architecture

DIGITIMES Intelligence released a report detailing an industry-wide transition toward 800VDC power architecture in AI data centers. This shift is driven by scaling AI computing, which has increased rack-level power requirements and forced a redesign of electricity delivery from the grid to compute systems.

The report identifies power delivery as a critical system-level design issue that directly impacts thermal management, conversion efficiency, and the overall system footprint. This transition is altering the competitive landscape for power semiconductors, specifically regarding the application of Gallium Nitride and Silicon Carbide technologies.

According to the analysis, competition is moving away from individual device specifications toward system-level design collaboration with original equipment manufacturers and original design manufacturers. The ability to ensure supply stability and adapt to rapidly changing AI platform requirements will determine value distribution across the global supply chain.
