As artificial intelligence (AI) redefines the scale and density of data center compute, the supporting infrastructure must evolve in lockstep. At Computex 2025, NVIDIA introduced its 800 VDC higher-voltage DC rack-level architecture, marking a significant step forward in the development of power systems designed for next-generation high-density AI factories.
Vertiv is proud to support this initiative as a foundational ecosystem partner. Our contributions are grounded in real-world experience, with more than 80 years of DC power innovation, nearly two decades of ±400 VDC deployments, and a global track record of delivering critical infrastructure at scale.
This step on the AI roadmap reflects Vertiv’s continued commitment to staying one GPU generation ahead in infrastructure design and readiness. Vertiv’s 800 VDC portfolio is scheduled to be commercially available in the second half of 2026—ahead of NVIDIA Kyber and NVIDIA Rubin Ultra compute platforms. Early access to reference designs and roadmaps allows customers to validate and deploy supporting infrastructure in parallel with emerging GPU systems, allowing performance alignment and accelerated time to value.
Why 800 VDC
AI compute platforms are rapidly pushing rack densities beyond 300 kilowatts. In these homogeneous, high-performance environments, traditional 415 VAC or 480 VAC architectures face limitations in copper volume, thermal loss, and space efficiency. Shifting to 800 VDC enables significant reductions in current, conductors, and conversion stages—while centralizing power conversion at the room level.
Vertiv’s 800 VDC portfolio will be designed and tested for these workloads, allowing operators to simplify rack designs, increase thermal flexibility, and support modular expansion within AI zones.
A mature foundation
Vertiv enters this transition from a position of strength. DC power solutions have long supported global telecom networks, industrial systems, microgrids, and critical megawatt-scale data center infrastructure deployments, all longtime Vertiv focus applications. We’ve deployed higher-voltage DC architectures safely and reliably, integrating solar PV, DC lighting, HVAC, and large-scale rectifier systems for critical applications globally. 800 VDC is a natural evolution of what we’ve already delivered globally, and Vertiv’s portfolio will be end-to-end, including centralized rectifiers, high-efficiency DC busways, rack-level DC-DC converters, and DC-compatible backup solutions, complementing an already robust AC power train.
What’s changing — and what’s not
Centralizing power conversion improves system efficiency and reliability, but it also introduces new considerations. Today, higher-current DC protection at this voltage is delivered through fuse-and-disconnect combinations, as the ecosystem for resettable breakers is still maturing. Fault detection and recovery are active areas of innovation—areas where Vertiv’s experience brings tangible value.
This higher-voltage DC architecture is designed for the highest-density, future generation GPU deployments. The 800 VDC portfolio complements Vertiv’s broad power train of AC and DC power systems that we expect to continue to support traditional enterprise and mixed-load environments and hybrid power applications. Vertiv’s ability to support both architectures — and guide customers between them — is a key differentiator.
Supporting “one unit of compute”
The shift to 800 VDC is fully aligned with Vertiv’s “one unit of compute” strategy — a systems-level design engineered to enable all infrastructure components to interoperate as one modular and scalable system that scales infrastructure to meet the power, thermal, and operational demands of next-gen racks. By designing infrastructure that matches the compute itself, we’re helping customers streamline deployment, increase efficiency, and prepare for future generations of AI.
We’re proud to be part of the NVIDIA 800 VDC ecosystem and committed to delivering the technologies and services that turn next-generation power architectures into operational reality.
