Shares of SK Eternix, a South Korean power supply manufacturer, climbed sharply in Seoul trading as investors positioned for increased demand from artificial intelligence data centers.

The Korea Herald reported that the rally was driven by expectations that the company’s power solutions will be essential for the next wave of AI infrastructure deployment.

The move highlights a broadening of the AI trade beyond semiconductor makers into the supporting hardware ecosystem.

While chipmakers like SK Hynix have captured most of the recent attention, investors are increasingly looking at the power and cooling infrastructure required to sustain high-density computing clusters.

SK Eternix, a subsidiary of the SK Group, specializes in power supply units and related components, positioning it as a direct beneficiary of the sector's capital expenditure cycle.

This development follows a period of strong performance for SK Group affiliates in global markets.
