The global AI Power Supply Units (AI PSU) Market is experiencing rapid growth as artificial intelligence workloads transform data center infrastructure. According to a new report from Fact.MR, the market was valued at $560.4 million in 2025 and is projected to increase from $698.3 million in 2026 to $6.3 billion by 2036, registering a compound annual growth rate (CAGR) of 24.6%. The industry is expected to create an absolute dollar opportunity of $5.6 billion, expanding nearly ninefold between 2026 and 2036 as enterprises, hyperscalers, and cloud providers invest heavily in AI-ready infrastructure.
The 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,” said 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 from the report include that multi-rail PSUs are expected to account for 62% of the market share in 2026, while PSUs with output ratings between 1,000W and 3,000W are projected to hold a 46% share. Hot-swappable PSUs are anticipated to capture 43% of the market, and air-cooled PSUs remain dominant with a 58% share. Regionally, India and China emerge as the fastest-growing markets, with CAGRs of 28.9% and 27.6%, respectively, through 2036. North America remains the largest market, with the United States projected to expand at a 25.8% CAGR, while Europe continues to invest in energy-efficient technologies, with Germany growing at 21.2% CAGR.
The rapid expansion 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.
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.
