Morgan Stanley: 800V DC Not Delayed; Mass Production Pace Aligns with Expectations

Overview

This brief note primarily clarifies the market rumor reported by SemiAnalysis on June 9 regarding the "delay of large-scale shipments of NVIDIA's native 800V DC power architecture until 2028." Morgan Stanley explicitly states that this news contradicts supply chain feedback obtained during Computex. Citing official statements from NVIDIA and the mass production progress of core supplier Delta Electronics, the report argues that the 800V DC technology roadmap is still advancing according to the established schedule, and the overall development trend remains undisturbed.

Core views

Refutation of Rumors and Verification via Official Channels: While there were market concerns about delays in the 800V DC architecture, Morgan Stanley points out through cross-verification with the supply chain that NVIDIA clearly stated at GTC Taipei that 800V DC development is ongoing, and 800V power racks will be ready for mass production in Q3 2026. Furthermore, R&D resources from major hyperscalers have refocused on 800V DC, shifting away from ±400V solutions, demonstrating the industry's firm commitment to this technology path. Clear Supplier Mass Production Schedule: The report specifically mentions that Delta Electronics (Delta Electronics) is poised to become the first supplier to achieve mass production of 800V DC standalone power racks, scheduled for Q4 2026, with customers being one of the major US hyperscale cloud providers. Although initial shipment volumes will be limited, and the development of 800V protection devices and the formulation of UL industrial safety standards will take time, this is a normal ramp-up process for new technology introduction and does not change the core judgment that the overall development of 800V DC is sound.

Analysis framework

The institution adopted a typical "rumor-verification" event-driven analysis framework. Facing market noise, analysts did not rely on a single source but compared media rumors with primary research information from recent industry exhibitions (Computex/GTC Taipei). The analytical logic unfolded along the chain of "confirmation of official technology roadmap → verification of core supplier mass production milestones → assessment of supporting ecosystem maturity," using specific quarterly timelines and manufacturer behaviors to qualitatively judge the continuity of industry trends, thereby reaching a conclusion opposite to the market's pessimistic expectations.

Methodology notes

• Industry/Industrial Analysis FrameworkUpstream, Midstream, and Downstream Transmission in the Industry Chain

  Verifying the technology implementation pace of downstream customers (NVIDIA/cloud providers) through the mass production readiness of core suppliers (e.g., Delta Electronics)

  In the hardware technology industry, the technology roadmap of terminal brands often requires cooperation from upstream component manufacturers to be implemented. By confirming the specific mass production timeline of power suppliers (Q4 2026), the report reversely proves that the 800V architecture has not been delayed. This is a more reliable verification method than simply believing market rumors.

• Event Gaming and Behavioral FinanceExpectation Gap/Expectation Management

  Identifying the deviation between market rumors and actual supply chain conditions as a basis for judgment

  When the market generates panic or adjusts expectations due to negative rumors, if institutions discover through primary research that the actual situation has not deteriorated or is even better than expected, this "expectation gap" often implies opportunities for mispriced assets or continuation of trends. The core value of this report lies in correcting the market's incorrect pricing of 800V progress.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Delta Electronics

  Beneficiary: Named as the first supplier to mass-produce 800V DC standalone power racks

  Strengths

  Leading technological R&D, tight binding with top US hyperscale cloud providers, clear mass production timeline (Q4 2026)

  Weaknesses

  Initial shipment volume is limited; must wait for completion of safety standard definitions such as UL

  Comparison

  Compared to other power suppliers, Delta Electronics has a clear first-mover advantage in the field of 800V standalone racks

  Risks

  Progress in formulating industrial safety standards falling behind expectations may affect the ramp-up rhythm

• NVIDIA (NVDA.US)

  Core Driver: Definition and demand side of the 800V DC architecture

  Strengths

  Clear technology roadmap, publicly denied delay rumors, guiding industry chain resources to focus on 800V

  Risks

  High market sensitivity to technology iterations; any developments can easily trigger stock price volatility

Key data

• Readiness Time for 800V Power Rack Mass ProductionQ3 2026Official milestone disclosed by NVIDIA at GTC Taipei, indicating readiness for deployment
• Mass Production Time for Delta Electronics' 800V Standalone Power RackQ4 2026Expected to begin shipments to top US hyperscale cloud providers
• Readiness Time for Next-Generation DC Power CenterQ2 20271.6MW Option 1B solution expected to be deployed and ready
• Readiness Time for Higher-Order Power BlockQ1 20284.8MW+ Option 1C solution expected to be deployed and ready; may have been misread by the market as an overall delay

Impact & implications

For investors focused on AI computing infrastructure, this briefing alleviates concerns about stagnation in power architecture iteration. 800V DC is a key technology supporting next-generation high-density AI computing clusters; its advancement on schedule means that the logic of increased value in the AI server industry chain remains intact. Meanwhile, the report implies that the competitive landscape in the power segment is differentiating, with suppliers possessing first-mover mass production capabilities (such as Delta Electronics) occupying favorable positions in the new technology cycle. Subsequent tracking should focus on industry thresholds such as配套 safety standards and protection device certifications.

Risks

• Development progress of 800V DC protection devices lags behind
• UL and major regulatory bodies take longer than expected to define 800V industrial safety standards
• Initial mass production yield or shipment ramp-up falls below market expectations

What to watch

• Actual shipment status of Delta Electronics in Q4 2026 and customer feedback
• Official release timing of 800V DC safety standards by institutions such as UL
• Latest guidance from NVIDIA on the 800V ecosystem in subsequent product launch events
