NVIDIA’s next-generation AI data center’s 800V high-voltage DC power supply plan has recently been rumored by the market to be “delayed in mass production,” but core supply chain partners Delta Electronics and ABB have come forward to clarify: everything is progressing on schedule.

Why the 800V Power Revolution Matters

The power consumption of AI servers continues to rise. Each H100 GPU consumes up to 350W, and a data center housing tens of thousands of GPUs can have total power usage comparable to a mid-sized city. The traditional 400V AC power architecture is approaching its limits, and NVIDIA sees 800V DC as a key upgrade for next-generation AI data centers.

The advantages of the 800V DC architecture include:

• Reduced Losses: DC power eliminates the need for frequency conversion, improving transmission efficiency by over 10%
• Space Saving: At the same power level, thinner cables are used, allowing more GPUs to be packed into racks
• Simplified Architecture: Fewer converters are needed, reducing data center maintenance costs

Latest Supply Chain Progress

According to a report by 21st Century Business Herald citing NVIDIA’s core energy ecosystem partners, including Delta Electronics and ABB, the 800V solution is still on track. The timeline is as follows:

• Q3 2026: Morgan Stanley notes that NVIDIA clearly stated at the GTC Taipei conference that the 800V DC development is progressing normally, and the supporting power racks are expected to reach mass production readiness by then
• Q4 2026: Delta Electronics will begin initial small batch deliveries of 800V independent power cabinets to top North American cloud providers

Texas Instruments (TI) also jointly released a complete 800V DC power architecture with NVIDIA in March this year, covering the full chain from power supply cabinets to GPU endpoints.

Not Just One Company’s Game

What truly determines the pace of this power revolution is not just NVIDIA’s technological rhythm, but an entire immature energy infrastructure industry chain. From power management ICs manufactured by TSMC, to power supply cabinets from Delta Electronics, to substation equipment from ABB, every link needs to be upgraded simultaneously.

Taiwan occupies a key position in this supply chain. As the global leader in power supplies, Delta Electronics’ 800V product line has entered NVIDIA’s certification list. The upgrade of Taiwan’s manufacturing power infrastructure may also become an early dividend for the expansion of AI data centers.

In contrast, the U.S. domestic power supply manufacturing ecosystem is relatively fragmented. Maine recently became the first in the U.S. – Maine Proposes Ban on Large Data Centers, AI’s High Power Consumption Sparks Public Outrage, showing that the pressure of AI power consumption on local grids has become a real issue, not a distant future challenge.

Market Reaction and Outlook

NVIDIA’s 800V DC special session at the GTC Taipei conference showcased a complete technology roadmap, covering modular data center design and plug-and-play power architectures. In its analysis report, Morgan Stanley emphasized that 2026 will be a turning point for AI hardware infrastructure, and the confirmation of the 800V DC mass production timeline means data center construction will accelerate into a new investment cycle.

As global AI data centers shift from “building houses” to “powering up,” the maturity of power infrastructure will become the next bottleneck determining the speed of AI expansion—and NVIDIA, along with the Taiwan supply chain, is already ahead.
