This dataset is a model of two bill-of-materials lines that are easy to mix up with the whole data-center power room: the server power supply, and the rack PDU. Delta, Lite-On, Bel Fuse, and Advanced Energy are examples on the power-supply side. Vertiv, Schneider, Eaton, and Legrand are examples on the rack-PDU side. Cooling, UPS plants, the utility feed, switchgear, liquid cooling, and utility substations are not in this dataset. Vertiv’s company revenue includes those other lines and is not used as this market. CPUs, accelerators, DRAM, SSDs, and NICs are not in this dataset. The data is provided starting in 2025 and forecasts through 2032. In 2025, we estimate an $8.63 billion total market. A unit count for that combined market was not published. From 2026 the same market is carried forward on three paths that share a downside, base, and upside case.
The market, 2025–2032
In 2025 the market was $8.63 billion, server power supplies of about $5.82 billion and rack PDUs of $2.81 billion added together. Our base forecast is $17.52 billion in 2032, a 10.6 percent compound rate from 2025, with $14.38 billion at the 2030 checkpoint. The downside case ends at $13.87 billion. The upside case ends at $21.30 billion. These figures are the two server-bill lines, not the power room around the rack.
Data set details
The model. The 2025 total is the two lines added together. Units and average selling price are blank, because a 2025 shipment count on the same scope was not published. Geography, the hyperscale share, and the efficiency mix are held flat through 2032.
The forecast. The data is provided for revenue by year on downside, base, and upside. All three paths share the 2025 total market. Base 2026 is $9.57 billion. Base 2032 is $17.52 billion. Downside 2032 is $13.87 billion. Upside 2032 is $21.30 billion.
Key players. Power-supply makers on the sheet are Delta, Lite-On, Bel Fuse, Advanced Energy, Flex, Murata, and Vicor. Rack-PDU makers are Vertiv, Schneider, Eaton, Legrand, nVent, Chatsworth, Panduit, Rittal, Huawei, ABB, CyberPower, and Enlogic. None of them is given an in-scope 2025 dollar of its own. Company revenue that mixes cooling and facility power stays out.
Key buyers and segments. The market is two segments: server power supplies and data-center rack PDUs. In the 2025 cut used for the power-supply piece, hyperscale buyers are 60 percent and Titanium-rated supplies are 44 percent. Those shares are applied to the combined picture and held flat in 2032.
The products. Product rows name common redundant power supplies, open-rack supplies, and rack-PDU families. The dated launch on the sheet is Vertiv PowerIT in September 2025. Its kilowatts were not in the summary, so that cell is blank.
Narratives and documents. The data set is accompanied by articles that explain the forecast methodology and assumptions, the market drivers, the challenges, the forecast, the companies, and the events to watch.
