The global Power Electronics for Data Centers Market was valued at USD 19.99 billion in 2025. It is estimated to reach USD 25.43 billion in 2026 and is projected to grow to USD 78.58 billion by 2036, at a CAGR of 11.9% during the forecast period. This report offers a detailed look at the market, covering market dynamics, the impact of technology, the regulatory and standards landscape, pricing, the value chain, power semiconductor content, competitive activity, and future growth opportunities.
The market covers the sales of equipment that converts, conditions, and switches electrical power between the utility feed and the processor, together with the drives that run cooling motors. It includes server and storage power supply units (PSUs), rack power shelves, HVDC power racks and sidecars, intermediate bus converters, and voltage regulator and point-of-load modules. It also includes the conversion electronics of modular and centralized UPS systems, rectifiers and DC power systems, solid-state transformers (SSTs), static transfer switches, and cooling motor drives. Each item is counted once at the equipment level that the buyer purchases, so silicon, SiC, and GaN devices are not counted separately. Switchgear, conventional transformers, cables and busway, basic PDUs, generators, and batteries are excluded.
Server makers and original design manufacturers (ODMs) buy PSUs, power shelves, and board-level converters for every server and rack they assemble, mainly in Taiwan, China, Mexico, and the U.S. Data center operators and their contractors buy UPS systems, rectifiers, static transfer switches, and cooling drives where each facility is built. Market value is measured at the vendor selling price and assigned to the country of purchase, which places much of the IT-side value in assembly countries. Rising AI rack power has moved a large part of this value into the rack. NVIDIA states that its 800 VDC architecture is designed for IT racks from 100 kW to over 1 MW, and it plans full-scale production from 2027.
The report examines market drivers, restraints, opportunities, challenges, and trends, along with the technology landscape of the power conversion chain from grid to chip. This covers silicon, SiC, and GaN devices, rack power shelves and battery backup, 800 VDC sidecars and SSTs, intermediate bus converters and voltage regulators, and drives for cooling systems. Coverage extends to the regulatory and standards landscape, pricing, the value chain, and power semiconductor content, while Porter's five forces and bear, base, and bull scenarios are also analyzed. In addition, it provides market forecasts in value, segment-level insights, and regional analysis across 5 regions, 21 countries, the Nordics, and 4 rest-of-region groups.
Cost and supply constraints for silicon carbide (SiC) and gallium nitride (GaN) devices restrain market growth. TSMC will stop GaN foundry production by the end of July 2027, according to Semiconductor Today (July 2025). Navitas expects customer transfers to its new GaN foundry to take 1.5-2 years, because each change of device source forces requalification. Some Delta shipments in the third quarter of 2026 were also delayed by power IC shortages, according to TechNews (September 2026). Long qualification cycles at hyperscale buyers form a second restraint. Navitas reported more than 40 design wins in 48 V data center power on its August 2025 call, and these wins ramp in 2026, roughly one to two years after they were won. A supplier that misses a qualification slot can lose a full accelerator generation.
Solid-state transformers (SSTs) for grid-to-rack conversion offer a significant opportunity, because one SST can replace the transformer, the rectifier, and part of the UPS stage in an 800 VDC hall. In October 2026, Vantage Data Centers secured more than 1 GW of manufacturing capacity for the Heron Link SST of Heron Power, according to Latitude Media. Vertical and high-density power delivery to accelerators offers a second opportunity. Vicor estimated vertical power delivery content at USD 200-400 per accelerator on its February 2026 earnings call. The replacement of aging UPS and power fleets offers a third opportunity. Eaton estimated in February 2026 that 35-40 GW of data center capacity was installed at the end of 2024. It also states that UPS fans typically wear out after 6-7 years, which gives operators regular points to replace older units.
Thermal density and reliability in compact power shelves remain a major challenge. The OCP shelf specification of June 2026 raised the rating to 72 kW, and Lite-On showed a 110 kW shelf at NVIDIA GTC in March 2026. Even at 98% efficiency, a shelf turns 2% of its throughput into heat inside a few rack units. Safety standards and arc protection for high-voltage DC form a second challenge. Schneider Electric stated in August 2026 that no industry-wide standard yet addresses hazards in converter-fed 800 VDC systems. The DC arc flash methods in NFPA 70E Annex D are informative only, and IEEE 1584 covers AC systems. Until common standards exist, each project needs extra engineering studies, approvals, and staff training.
Key trends include the adoption of wide-bandgap (SiC and GaN) devices. Navitas puts power semiconductor content at about USD 10-20 million per GW in 48 V AI data centers and USD 30-50 million per GW in 800 V designs. Most of the 800 V converters shown at NVIDIA GTC in March 2026 used GaN, according to Power Electronics News. OCP Open Rack power standards and disaggregated power racks form a second trend. The Open Compute Project published the Mt. Diablo specification v1.0.0, contributed by Microsoft, Meta, and Google, in October 2026. It defines ±400 VDC power racks of 800 kW to 1.1 MW. Digital and AI-based power control is a third trend, as the NVIDIA Vera Rubin NVL72 rack carries 20 times more energy storage to keep power steady, according to NVIDIA (October 2025). The Delta SiC e-Fuse also clears faults in under 3 μs.
Based on product type, the market is segmented into power supply units & power shelves, DC-DC converters & voltage regulation, UPS power conversion systems, rectifiers & DC power systems, solid-state transformers, static transfer switches, and cooling motor drives. In 2026, power supply units & power shelves are expected to hold the largest share, because this first conversion stage is needed in every server and every AI rack. AI-related power supplies made up 23% of Delta revenue in the first nine months of 2025, according to the Taipei Times. Solid-state transformers are expected to grow the fastest from a small base, as 800 VDC halls adopt equipment that converts medium-voltage AC directly to DC. UPS power conversion systems form the second-largest product type, while rectifiers & DC power systems grow the slowest because -48 V telecom spending is mature.
Based on power supply units & power shelves, the market is segmented into server & storage power supply units, rack power shelves, and HVDC power racks & sidecars. Server & storage power supply units hold the largest share in 2026 and remain the largest sub-type until 2030. Rack power shelves lead in 2031-2033, as 48-54 V shelf ratings rise from 33 kW to 72 kW and above. HVDC power racks & sidecars are expected to grow the fastest and to become the largest sub-type from 2034. This is supported by the OCP Mt. Diablo specification and the full-scale 800 VDC production that NVIDIA plans from 2027.
Based on DC-DC converters & voltage regulation, the market is segmented into intermediate bus converters and voltage regulators & point-of-load modules. Voltage regulators & point-of-load modules hold the larger share, because every processor socket needs a multiphase regulator. Intermediate bus converters are expected to grow faster, as 800 VDC racks add converters such as the 800 V to 50 V ADH series that Advanced Energy introduced in June 2026. Based on UPS power conversion systems, the market is segmented into modular UPS and centralized UPS. Centralized UPS remains the larger sub-type until 2032, while modular UPS grows faster and leads from 2033, as AI halls are built out in phases.
Based on semiconductor technology, the market is segmented into silicon-based, SiC-based, and GaN-based. In 2026, silicon-based equipment is expected to hold the largest share, due to the large installed base and the continued use of silicon in voltage regulators, drives, and UPS systems. It remains the largest segment in every year of the forecast period. GaN-based equipment is expected to grow the fastest, driven by compact AI PSUs and new 800 V DC-DC converters inside compute racks. SiC-based equipment is the second-fastest-growing technology, led by HVDC rectifiers, 800 VDC sidecars, and SSTs.
Based on rack power architecture, the market is segmented into 12 V legacy architecture, 48-54 V DC architecture, and high-voltage DC (400/800 VDC) architecture. In 2026, the 48-54 V DC architecture is expected to hold the largest share, owing to the production ramp of Open Rack V3 (ORv3) racks and NVIDIA GB200 and GB300 NVL72 systems. It overtook the 12 V legacy architecture as the largest in 2026. The high-voltage DC architecture is expected to grow the fastest, as NVIDIA notes that 54 V distribution starts hitting physical limits above 200 kW per rack. The 12 V legacy architecture stays broadly flat until 2031 and declines from 2032, as conventional halls are refreshed with higher-voltage designs.
Based on data center type, the market is segmented into hyperscale & AI data centers, colocation data centers, enterprise data centers, and edge & telecom data centers. In 2026, hyperscale & AI data centers are expected to hold the largest share, due to the scale of AI campus construction and the high power content of each AI rack. This segment is also expected to grow the fastest during the forecast period. Colocation data centers form the second-largest segment, as their operators buy UPS systems, transfer switches, and cooling drives for multi-tenant halls. Enterprise data centers grow the slowest, because spending centers on upgrades and replacement rather than new capacity.
In 2026, Asia-Pacific is expected to account for the largest share of the global market, mainly due to purchases of server PSUs, power shelves, and board-level converters by ODMs in Taiwan and China. China is the largest market in the region, followed closely by Taiwan. Both are expected to grow below the global market as server assembly for U.S. buyers shifts to Mexico and the U.S. Malaysia and India are the fastest-growing markets in the region. Tenaga Nasional Berhad cut grid connection time for new data centers in Malaysia from 36-48 months to 12 months, and Google will invest USD 15 billion in an AI hub in Visakhapatnam, India.
North America is the second-largest region, and the U.S. is the largest country market in every year of the forecast period. The region is the largest buyer of facility-level power conversion equipment, as U.S. data centers used 175 TWh of electricity in 2024, according to Uptime Institute (November 2025). U.S. hyperscalers and neoclouds are also the first large buyers of high-voltage DC power racks and SSTs. Vantage Data Centers secured more than 1 GW of SST manufacturing capacity from Heron Power in October 2026, and Eaton acquired the Austin-based SST developer Resilient Power Systems in August 2025.
Europe is the third-largest region, with Germany as its largest country market in 2026, while the U.K. is expected to take the lead by 2036. The Nordics are projected to grow the fastest in Europe, supported by AI campuses such as the 230 MW Stargate Norway site in Narvik. Grid limits slow growth in Ireland and the Netherlands, where Dutch operators face transformer lead times of up to three years. Data centers also used 21% of Irish electricity in 2023, according to the CRU. Efficiency rules such as the German Energy Efficiency Act push operators to replace older UPS systems and cooling drives.
In Latin America, Mexico accounts for most of the market, as ODMs assemble AI servers there for U.S. hyperscalers. Mexico passed Taiwan in monthly server sales to the U.S. for the first time in May 2026, according to Mexico News Daily. The Middle East & Africa is expected to grow the fastest during the forecast period, from the smallest base of all regions. Saudi Arabia is the fastest-growing country, where HUMAIN targets 1.7 GW of capacity in 2027. The UAE is the largest market in the region, where Khazna is building the 1 GW Stargate UAE cluster in Abu Dhabi.

Market Dynamics
The rising rack power density of AI systems is the main force behind market growth. The Register (May 2025) put typical racks at roughly 5-30 kW and the NVIDIA GB200 NVL72 at about 120 kW. NVIDIA CEO Jensen Huang said at GTC 2025 that the Kyber rack for Rubin Ultra will draw up to 600 kW, according to Tom's Hardware (March 2025). Texas Instruments cites a roughly 70% increase in current demand per GPU generation, according to Power Electronics News (March 2026). The shift to 800 VDC and higher-voltage power architectures forms a second driver. NVIDIA states that 800 VDC gives up to 5% better end-to-end efficiency than 54 V systems, and it plans full-scale production from 2027. Efficiency mandates and energy cost pressure are a third driver. The IEA (April 2025) projects data center electricity use to rise from about 415 TWh in 2024 to about 945 TWh by 2030. EU Ecodesign Regulation 2019/424 has also required single-output server PSUs to reach 96% efficiency at 50% load since January 2023.Cost and supply constraints for silicon carbide (SiC) and gallium nitride (GaN) devices restrain market growth. TSMC will stop GaN foundry production by the end of July 2027, according to Semiconductor Today (July 2025).
