800 VDC Data Center Power Architecture Market Size Worth USD 59.76 Billion By 2034 | CAGR: 15.6%

The global 800 VDC data center power architecture market size is expected to reach USD 59.76 billion by 2034, according to a new study by Polaris Market Research. The report, "800 VDC Data Center Power Architecture Market Size, Share, Trends, & Industry Analysis Report By Power Architecture, By Deployment Type, By MV to 800 VDC Conversion System, By Downstream Conversion Stage, By Region – Market Forecast, 2026–2034" gives a detailed insight into current market dynamics and provides analysis on future market growth.

Rising AI workloads are increasing the power drawn by each data center rack, and operators are evaluating 800 VDC distribution as a way to deliver that power with fewer conversion stages, lower distribution losses, and less equipment in the rack. Most installed capacity still runs on AC distribution, so sidecar designs are giving operators a way to add 800 VDC racks to existing facilities, while new AI campuses can plan for hybrid and native 800 VDC from the start.

Advances in power conversion are widening the range of products available to buyers. Solid state transformers, silicon carbide, and gallium nitride devices are moving into product development, and suppliers are introducing converters that step 800 VDC down to the lower voltages servers need in fewer stages. Equipment makers including ABB, Eaton, Infineon Technologies, Siemens, and Flex announced 800 VDC products or partnerships during 2026, while safety and protection standards for high voltage DC in data halls are still developing.

"Power architecture is now being decided at the start of AI data center projects. Operators planning megawatt class racks are evaluating 800 VDC distribution alongside the compute design, which opens demand for conversion, protection and distribution equipment built for the voltage."
