NVIDIA 800 VDC Architecture
A scalable facility-to-rack power architecture to power next-generation AI factories.
Overview
Power Infrastructure for the AI Factory Era
As rack power rises, conventional low-voltage distribution can require more conductors, conversion equipment, and space. NVIDIA 800 VDC provides an evolutionary path to higher-density facility-to-rack power delivery. Depending on the facility design, it can reduce conductor requirements and eliminate or simplify conversion stages while supporting incremental adoption.
From AC to VDC
Moving to an 800 VDC Architecture
Data center architectures will gradually evolve from today's AC distribution to 800 VDC. The NVIDIA 800 VDC architecture supports all existing data centers while providing a smooth path to an all 800 VDC future.
Data Center Roadmap
Architecting AI Infrastructure for Next-Gen AI Factories
The 800 VDC architecture offers flexible deployment options—from rack-level power racks for hybrid integration in existing facilities, to cluster-level power centers and data hall-level power blocks for next-generation AI factories.
Features
Power AI Factories With 800 VDC
NVIDIA 800 VDC supports higher-density facility-to-rack power delivery by increasing distribution voltage and simplifying the power path where the selected facility design permits.
Fewer Conversion Stages
Eliminate or simplify conversion stages where the facility architecture supports 800 VDC distribution.
Lower-Current Distribution
Reduce current and conductor requirements for a given power level, helping simplify power delivery to high-density racks.
Industry Ecosystem
Advance a common 800 VDC direction with NVIDIA, Google, Microsoft, OCP, and partners across the data center electrical ecosystem.
Facility-to-Rack DC Power
Distribute 800 VDC through the facility and use it directly at the compute rack, minimizing loss and complexity in the power path.
Technology
Transition to Higher-Voltage DC Power
The common rack structure can support conventional AC-fed power shelves and 800 VDC configurations, allowing operators to evolve the electrical architecture without replacing the mechanical and cooling foundation.
Flexible Facility Architectures
Use 800 VDC in a configuration designed for the facility’s distribution topology, protection strategy, electrical codes, and transition plan.
Industry-Aligned Architecture
NVIDIA is working with the electrical and AI infrastructure ecosystem to advance a common, scalable direction for 800 VDC deployment.
Rack-Ready DC Power
Carry 800 VDC from facility power distribution directly to the compute rack, creating a streamlined path for high-density AI systems.
Benefits
Power More Compute in the Same Footprint
NVIDIA 800 VDC reduces end-to-end conversion stages and distribution losses, helping AI factories deliver more power to productive compute as rack density grows.
Reduce Space and Complexity
Use more compact switchgear, distribution boards, and busways to improve space efficiency and reduce system complexity.
Support Future AI Servers
Support high-density AI deployments with an architecture designed for the power needs that future AI servers will demand.
Make More Site Power Available to Compute
Simplify conversion and distribution where the facility design permits, reducing infrastructure overhead that can limit usable IT capacity.
Future-Proof AI Factories
Prepare AI factories for future server generations with a power architecture designed to evolve as rack density and power requirements rise.
