SemiAnalysis forecasts that Nvidia's native 800V high-voltage direct current power architecture may not see large-scale deployment until beyond 2028, later than the market previously expected in 2027.
Why it matters
The delay threatens growth prospects for companies in the AI power supply chain, which have been preparing for earlier adoption of this more efficient power technology.
What to watch
The forecast challenges prior market expectations; investors and suppliers should monitor whether Nvidia meets any revised timeline and how competitors respond to the extended wait.
SemiAnalysis released a forecast indicating that Nvidia's native single-ended 800V high-voltage direct current power architecture may not achieve large-scale deployment as soon as the market previously anticipated. The market had expected this deployment in 2027, but SemiAnalysis now forecasts it could slip to beyond 2028. The delay raises concerns over growth prospects for the AI power supply chain, the ecosystem of companies that design, manufacture, and supply power delivery components for AI data centers and infrastructure. The shift in timeline suggests either technical hurdles, manufacturing constraints, or slower-than-expected customer adoption of the 800V standard, any of which would push back the transition from earlier power architectures. For suppliers and manufacturers who have been preparing product launches and capacity planning around a 2027 ramp, this extended timeline requires recalibration of business strategies and investment priorities.
SemiAnalysis's forecast represents a significant shift in expectations around Nvidia's 800V high-voltage direct current power architecture, a native single-ended system designed to improve power efficiency for AI infrastructure. The delay from a previously expected 2027 deployment to potentially beyond 2028 signals challenges in the readiness or adoption timeline for this technology. For the AI power supply chain—a sector that includes manufacturers and suppliers of power delivery components—the delay creates uncertainty about revenue timing and product roadmap priorities. Companies have been positioning themselves to capitalize on early adoption of more efficient power solutions, so an extended timeline may compress near-term growth expectations.
