AI Power Supply Units Market to Reach USD 6.3 Billion by 2036 Amid Surging Investments in AI Data Centers

The global AI Power Supply Units (AI PSU) market is witnessing rapid expansion as artificial intelligence workloads continue to reshape data center infrastructure worldwide. According to Fact.MR, the market was valued at USD 560.4 million in 2025 and is projected to grow from USD 698.3 million in 2026 to USD 6.3 billion by 2036, registering a remarkable 24.6% CAGR during the forecast period. The industry is expected to create an absolute dollar opportunity of USD 5.6 billion, expanding nearly 9X between 2026 and 2036 as enterprises, hyperscalers, and cloud providers invest heavily in AI-ready infrastructure.

Growing adoption of artificial intelligence, machine learning, high-performance computing (HPC), and generative AI applications is significantly increasing power density requirements across modern data centers. As a result, demand for high-efficiency, high-wattage power supply units capable of supporting advanced GPU clusters and AI servers is accelerating worldwide. "The AI PSU market is no longer driven by traditional server power requirements alone," says Shambhu Nath Jha, Principal Consultant at Fact.MR. "Hyperscale AI data center expansion, rising GPU deployments, and the need for energy-efficient computing are transforming power supply units into a critical component of next-generation digital infrastructure."

Key market highlights include multi-rail PSUs accounting for 62% market share in 2026, 1,000W–3,000W PSUs holding 46% share by output rating, hot-swappable PSUs capturing 43% share, and air-cooled PSUs remaining dominant with 58% market share. India (28.9% CAGR) and China (27.6% CAGR) emerge as the fastest-growing markets.

The rapid growth of hyperscale data centers and cloud computing infrastructure is creating substantial demand for advanced power delivery systems. AI workloads require higher energy consumption than traditional computing environments, making efficient and reliable PSU solutions essential for operational performance. Multi-rail power supply units are gaining widespread adoption because they provide superior load balancing, improved safety, and enhanced reliability in high-density AI server environments. Meanwhile, demand for hot-swappable and modular PSU configurations is increasing as operators seek uninterrupted operations and simplified maintenance.

North America remains the largest market, supported by investments from major cloud providers and AI infrastructure developers. The United States is projected to expand at a 25.8% CAGR through 2036. In Asia Pacific, rapid digital transformation and data center investments are driving exceptional growth. India is forecast to register the highest growth rate globally at 28.9% CAGR, while China is expected to grow at 27.6% CAGR, supported by government-backed AI initiatives and strong domestic manufacturing capabilities. Europe continues to invest in energy-efficient data center technologies, with Germany projected to grow at 21.2% CAGR during the forecast period.

The market remains semi-consolidated, with leading manufacturers focusing on efficiency, power density, thermal management, and OEM partnerships. Key companies operating in the AI PSU market include Delta Electronics, Inc., LITE-ON Technology Corporation, AcBel Polytech Inc., FSP Group, Advanced Energy Industries, OmniOn Power Inc., Shenzhen Megmeet Electrical, and Great Wall Power Technology Co., Ltd. Industry innovation is increasingly centered on high-efficiency architectures, liquid-cooling compatibility, Gallium Nitride (GaN) technologies, Silicon Carbide (SiC) power electronics, and smart power management systems.

As AI infrastructure deployment accelerates globally, advanced power supply units are expected to become a critical enabler of data center performance, energy efficiency, and operational reliability. For more detailed analysis, the full report is available at Fact.MR.
