NVIDIA’s 800 VDC plan includes a phased rollout that operates alongside existing AC distribution systems. The adoption level depends on each facility individually, rather than replacing an entire plant all at once. In the short term, NVIDIA’s Power Rack delivers 800V DC into the compute racks and standardizes the DC interface and backup configuration so it can fit existing AC infrastructure. Following this, a row-level Power Center manages centralized rectification and supplies a full high-density row via a busway, reducing cabling complexity in white space. Over the longer term, a hall-level DC Power Block becomes the standard power building block, supporting higher-density loads. NVIDIA will collaborate with industry partners to expand demonstration and pilot sites ahead of large-scale deployment.

AI is only as powerful as the infrastructure behind it. Our NVIDIA 800 VDC power architecture helps unlock compute density and performance. With system-level reference designs, there’s a practical path to upgrade existing infrastructure now and scale for the decade ahead. The future of AI infrastructure is being built today. ➡️

Wolfspeed $WOLF & LITEON are partnering on 800 VDC power solutions for next-generation AI data centers. LITEON has qualified Wolfspeed’s silicon carbide technology for its power sidecar and compute-rack PSU platforms targeting hyperscalers, with potential for broader CSP adoption

As AI workloads push data centers beyond traditional limits, the industry is moving toward 800 VDC to power the next generation of AI infrastructure. Discover how this architecture can improve efficiency, reduce power losses and support megawatt-scale AI deployments, and how Flex is working with @nvidia to turn the 800 VDC roadmap into infrastructure that can be deployed at scale.

New research notes out in CS Atlas on our takes from the CPO Summit at AI infra summit and some conversations we had on 800 VDC transition and timing.

Important SST update from $SEDG this morning, just ahead of its Investor Day. First, the three-phase medium-voltage to 800 VDC conversion stage of its DC powertrain is now operating under load in the lab, with system-level validation of the full path underway. This keeps the “working system by end of 2026” milestone on track. Second, $SEDG published a joint white paper with NVIDIA: “800 VDC Protection and Grounding for AI Data Centers.” When I wrote my Deep Dive, there was no public link between the two companies beyond Infineon. Now $SEDG is co-developing and publishing the protection framework for the exact architecture NVIDIA is pushing the industry toward, with SolarEdge’s own reference implementation used as the worked example. One of the risks I flagged was that 800 VDC safety standards and certification pathways are still evolving. This is basically $SEDG positioning itself to meet those requirements as they emerge. Importantly, the paper carries an explicit non-endorsement statement from NVIDIA and emphasizes an open, multi-vendor ecosystem. There's still no pilot customer or order here. What changed today is credibility. Disclosure: I own a position.

Powering the Next Era of AI: How Google, Microsoft and Nvidia Are Standardizing and Accelerating the Industry Transition to LVDC Three of the world’s largest AI infrastructure builders are collaborating within OCP to establish 800 VDC as the open, standardized power architecture for next-generation AI data centers and to make sure the entire industry can adopt it safely, at scale. AI infrastructure is entering a new power era. As models become more capable and inference demand grows, AI accelerators are being deployed in denser, more tightly coupled systems. Those systems require more power per rack, more coordinated facility design and a power distribution architecture that can scale without forcing every operator or supplier into a custom design. The industry is converging on 800 VDC because higher-voltage DC distribution can move more power with less conductor/copper than lower-voltage alternatives. That matters as AI rack densities rise. Lower current can reduce cable and conductor burden, simplify distribution and create a more practical path for high-density AI deployments. Google, Microsoft and NVIDIA are working through OCP with the broader power, cooling, facility and infrastructure ecosystem to align on common 800 VDC requirements. The goal is not a single prescriptive design. The goal is a common set of interfaces and system requirements that lets operators deploy safely, suppliers build interoperable products and the industry move faster together.

Morgan Stanley says SemiAnalysis' report on Nvidia's planned large-scale shipments of 800VDC power architecture being pushed back to 2028 is contrary to their own supply chain checks at Computex. "Nvidia at GTC Taipei Indicated 800 VDC developments are ongoing with 800 VDC power rack being ready for mass production in 3Q26. +-400 VDC development has been redirected to 800 VDC focus across various hyperscalers."

What does it take to build an AI factory ready for the agentic era? 80+ partners joined Jensen Huang at #NVIDIAGTC# Taipei to show how NVIDIA MGX is making it possible. With NVIDIA Vera Rubin, 800 VDC, and partners spanning systems, power, and cooling, NVIDIA MGX is turning modular design into deployed AI infrastructure for the agentic AI era. ⚡ #NVIDIAGTC# 🔗
