GaN for Data Center Power Supply Market, Trends and Growth Outlook 2026–2034

GaN for Data Center Power Supply Market is emerging as a critical enabler for next‑generation cloud and AI infrastructures. Industry analysts anticipate a sustained acceleration of adoption as hyperscale operators, hyperscale cloud providers, and edge‑computing facilities seek to replace legacy silicon‑based converters with gallium nitride (GaN) solutions that promise superior efficiency, higher switching frequencies, and reduced thermal footprints.

GaN power devices are increasingly being integrated into server‑level power supplies, high‑density storage arrays, and networking equipment, delivering up to 30% improvement in conversion efficiency and cutting cooling loads dramatically. This efficiency uplift translates directly into lower total‑cost‑of‑ownership (TCO) for data centre operators, enabling tighter power budgets while supporting the relentless drive toward higher compute density and sustainability goals.

Data Center Energy Efficiency: The Primary Growth Engine

The report highlights that the surge in global data‑center construction-projected to exceed 12 GW of new capacity annually by 2034-creates a compelling demand for power conversion technologies that can deliver higher efficiency at lower heat output. GaN devices meet these requirements by operating at switching frequencies three to five times greater than silicon counterparts, allowing designers to shrink magnetic components, reduce bill‑of‑materials, and free up valuable rack space. Moreover, the tighter thermal envelope supports aggressive power‑density targets of 10 kW per rack unit (U), which is a pivotal metric for hyperscale operators.

Regulatory pressures, such as the European Union’s “Green Deal” and the United States’ Energy Star for data centres, are also nudging operators toward greener power solutions. GaN’s ability to achieve conversion efficiencies above 95% positions it as a cornerstone technology for meeting mandatory PUE (Power Usage Effectiveness) targets below 1.2 across most regions.
