Enteligent White Paper Finds 800VDC-to-50VDC Rack Architecture Removes Fundamental Bottleneck to AI Data Center Growth

MORGAN HILL, Calif.--(BUSINESS WIRE)--Enteligent, developer of direct current (DC) power infrastructure for high-density loads, released a new technical white paper titled “800VDC-to-50VDC Power Delivery Architecture: Completing the DC-Native Power Stack for AI-Scale Data Centers.” The report examines how next-generation data centers can improve electrical efficiency and power density by adopting high-voltage direct current (HVDC) distribution paired with rack-level DC power conversion.

The new white paper builds on research published by Enteligent in February 2026, examining the advantages of facility-level 800VDC power delivery for next-generation AI and GPU data centers, such as power efficiency, lower total cost of ownership and scalability. As AI workloads drive rack power levels beyond 100 kW and push facilities toward multi-hundred-megawatt and gigawatt-scale deployments, traditional AC-based electrical infrastructure is reaching practical limits. A DC-native architecture that distributes power at 800VDC across the facility and converts it to 50VDC within the rack better aligns with the actual internal power infrastructure of modern servers.

“AI is fundamentally reshaping data center power requirements. While 800VDC distribution solves the upstream limitations of traditional AC infrastructure, converting it directly to a 50VDC server bus within the rack addresses the final conversion bottleneck at the server level,” said Sean Burke, CEO at Enteligent. “The combination of 800VDC facility distribution with rack-level 800VDC-to-50VDC conversion represents a complete, DC-native power architecture that aligns with the realities of modern data center requirements.”

The white paper discusses the tangible benefits of centralizing AC-to-DC conversion into fewer, higher-utilization systems that rely on compact, efficient conductor infrastructure and highly efficient rack-level converters to serve the IT load. The lowest total cost of ownership and highest operational efficiencies are achieved when High-Voltage DC (HVDC) is implemented as a facility-native architecture paired with rack-level 800VDC-to-50VDC conversion. Notably, the research found an AI rack in a DC-native architecture can generate 10x to 15x more revenue than a traditional rack in the same square footage.

"Power density is revenue density, and this architecture unlocks both. Every percentage point of efficiency recovered from unnecessary AC conversion translates directly into lower operating costs, reduced cooling infrastructure, and more usable compute per square foot of data center floor space,” said Frank Smith, VP of Growth at Claros, a power-management platform company developing advanced power delivery technologies for data centers. “Claros and Enteligent share the same perspective that by eliminating 15 to 20 kW of wasted heat per rack, you address one of the more persistent cost and scaling barriers for AI and GPU data centers."

Enteligent's white paper further shows how centralized rack conversion in an 800VDC-to-50VDC architecture can provide a unified electrical platform for all data center workload types, including traditional enterprise and storage servers, GPU compute and next-generation AI infrastructure.
