Episil Technologies Chairman: NVIDIA's 800VDC Architecture Still on Track for 2027 as Planned
Taylor Wilson
Episil Technologies chairman Hsu Chien-hua denied rumors of a delay to Nvidia's 800VDC architecture, confirming the 2027 timeline stands — a signal that silicon carbide demand driven by AI power upgrades remains alive.
What is 800VDC, and why does the market care so much?
Nvidia plans to shift data-center power delivery from the conventional 48V DC to an 800V DC (800VDC) architecture by 2027.
In plain terms = raising the voltage more than tenfold lets the same cables deliver far more power with less heat and line loss — it is the "power-grid upgrade" that follows AI's electricity surge.
Recent rumors suggested the rollout might slip. That hit silicon carbide (SiC — a semiconductor material that handles high voltage and high heat) stocks hard, because 800VDC is SiC's most certain high-volume use case.
What exactly did the chairman say?
Episil Technologies chairman Hsu Chien-hua told *Tech Taiwan*: "Nvidia's goal has always been to roll out 800VDC in 2027. As far as I know, everything is still on that timeline."
This means → the delay rumor has been denied by a supply-chain insider, and the SiC demand outlook has not been pushed back.
Episil is a Taiwanese power-semiconductor company sitting upstream in the SiC supply chain — Hsu's statement carries direct industry weight.
What other "surprise shortages" is the AI boom creating?
One industry executive quoted in the article said: "A lot of things we never thought could be in short supply have suddenly become scarce."
Beyond memory entering a "super-cycle" — which was broadly expected — IC substrates, printed circuit boards (PCBs), copper-clad laminates, and passive components have all hit severe shortages.
This reflects a reality broader than chips: the AI shock has spread from "compute" to "power" and "base materials," repricing the entire supply chain.
Who is benefiting most from these shortages?
The squeeze has pushed Unimicron and Elite Material past the NT$1 trillion market-cap mark.
Yageo chairman Pierre Chen became Taiwan's richest person — passive components, once a "low-profile part," delivered some of the biggest gains.
This means → AI supply-chain opportunities have migrated from "star chip stocks" to upstream materials and basic components. The market is relearning who the bottleneck is.
Could silicon carbide be the next "surprise winner"?
*Tech Taiwan* flagged SiC as the next material likely to face an "unexpected shortage" — once 800VDC lands, demand for SiC power devices will jump sharply.
The catch: most SiC companies are still losing money, burning cash to build capacity.
Put simply = SiC is the semiconductor industry's consensus "dream material," but the dream has not yet turned into profit. Whether 800VDC arrives on schedule in 2027 is the make-or-break timeline for SiC companies.
