Nvidia’s push for an HVDC 800V power design has opened a new growth window for the power management supply chain heading into 2026. IC distributors said that as AI infrastructure investment accelerates, demand for 400-800V solutions is gaining traction. With Taiwanese firms stepping into power module development, component demand is set to rise in tandem.

The economics of advanced semiconductor manufacturing in the US differ sharply from those in Taiwan, and TSMC’s experience in Arizona is underscoring how difficult that gap is to bridge. Analysts say higher depreciation per wafer and elevated labor costs are placing sustained pressure on margins at the company’s US fabs, even as production ramps up.
