Shares of TIANYU SEMI (02658) surged more than 6% in today's session.

At the time of writing, the stock was up 5.92% to HK$51.9, with a turnover of HK$3.2783 million.

Key Catalysts for the Move

Reports indicate that due to the dramatic increase in power consumption by AI data centers, the commercial implementation of an 800V high-voltage direct current (HVDC) power supply architecture is expected to be accelerated.

It is reported that Nvidia's Vera Rubin platform and Google's next-generation AI data centers will be among the first to adopt this solution, potentially driving a new wave of upgrades in AI infrastructure.

A research report from Kaiyuan Securities points out that silicon carbide (SiC) is entering a new phase of growth in both volume and value.

Nvidia's push to upgrade data center power architectures to 800V HVDC is significantly boosting the value and penetration rate of SiC.
