NVIDIA 800 VDC Architecture
Power delivery for the AI servers and factories of the future.
Overview
Powering AI Factories With 800 VDC
The AI revolution is causing data centers to rapidly outgrow their traditional power delivery methods. As data centers transform into AI factories, the legacy 54 V standard has become a bottleneck.
NVIDIA 800 volts direct current (VDC) has emerged as the optimal architecture for next-generation power distribution. It decreases conversion and routing volumes in the compute space while minimizing data center distribution losses and total end-to-end conversion stages. 800 VDC significantly reduces current, copper use, and cable bulk compared to rack-level 54 VDC systems and facility-level 480 volts alternating current (VAC) systems, while remaining safe and scalable. For operators, this means better AI token efficiency and the ability to pack more computing power into the same footprint, making 800 VDC the essential foundation for the next generation of intelligence.
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.
The top diagram shows today's data center, with multiple AC-to-AC conversions before being converted to DC at the compute rack. The bottom diagram shows the AI factory of the future, with a single AC-to-800 VDC conversion. 800 VDC is distributed within the data center and used directly by the compute rack.

Benefits
The Advantages of 800 VDC Technology
Support Future AI Servers
Future generations of AI servers will need more power than today’s 54 VDC architectures can support.
Maximize Token Efficiency
800 VDC architectures minimize energy losses due to multiple AC-to-DC conversion steps and maximize tokens per watt in AI factories.
Reduce Space and Complexity
An 800 VDC architecture enables more compact switchgear, distribution boards, and busways, improving space efficiency and reducing complexity.
Future-Proof AI Factories
By moving to 800 VDC, AI factories and data centers can be ready for future generations of AI servers.
