The market is projected to reach USD 21.84 billion by 2035, a CAGR of 13.66% from 2025. **How fast is the Data Center Power Supply Unit Market growing?** 13.66% a year from 2025 to 2035, after 13.79% a year from 2020 to 2025, because AI racks carry 2.5 times the PSU value per kW of conventional servers and their shipments grow almost sevenfold. **What does a data center power supply unit do?** USD 6.07 billion of 2025 spending went to units that convert facility power into the direct current servers, storage and switches use. AI racks group them in power shelves; 800 VDC designs move conversion into separate power racks. **Which product type leads the Data Center Power Supply Unit Market?** 46.6% of 2025 value, or USD 2.83 billion, goes to conventional server PSUs. 800 VDC power racks and converters grow fastest and reach USD 14.55 billion, 66.6% of the market, by 2035 (DC Market Insights estimate). **How much do data center power supplies cost per kW?** About USD 150 per kW of IT load for conventional servers and USD 375 per kW for AI rack power shelves in 2025, and USD 470 per kW for 800 VDC racks in 2026 (DC Market Insights unit values). **How many power supplies does an AI rack use?** 48 PSUs of 5.5 kW in eight power shelves feed an NVIDIA GB200 NVL72 rack that draws about 120 kW, according to NVIDIA. That is 264 kW of PSU rating, about USD 45,000 of hardware per rack (DC Market Insights). **What is 800 VDC power for data centers?** USD 14.55 billion of 2035 PSU spending goes to 800 VDC power racks and converters in the DC Market Insights model. NVIDIA plans full-scale 800 VDC production with Kyber racks in 2027, citing up to 5% better efficiency. **Which region leads the Data Center Power Supply Unit Market?** 46.0% of 2025 value, or USD 2.79 billion, is spent in North America. Middle East and Africa grows fastest at 20.91% a year, and Saudi Arabia is the fastest-growing country in the top 12 at 23.53%. **Who are the leading data center power supply companies?** About 33% of 2025 value is held by Delta Electronics (DC Market Insights assessment). Lite-On Technology, Advanced Energy, Chicony Power and AcBel Polytech follow; the top five hold about 74%. **Why do Data Center Power Supply Unit Market estimates differ?** USD 7.12 billion in 2026 is the DC Market Insights figure for PSU hardware only. Estimates that add UPS systems, PDUs, battery backup units, power semiconductors or non-data-center power supplies are larger. ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 6,070 | USD million | | Revenue CAGR | 13.66 | % | | Market size 2035 | 21,840 | USD million | ## Frequently asked questions ### What is the size of the Data Center Power Supply Unit Market in 2026?
