Data Center Power Supply Unit Market Size, Share & Forecast to 2035

The Data Center Power Supply Unit Market is valued at USD 7.12 billion in 2026 and is projected to reach USD 21.84 billion by 2035, up from USD 6.07 billion in 2025, a compound annual growth rate (CAGR) of 13.66% from 2025 to 2035 (DC Market Insights estimate). The value in a power supply unit (PSU) is moving from the pair of small supplies inside each general-purpose server to the shelves that feed a whole artificial intelligence (AI) rack: an NVIDIA GB200 NVL72 rack draws about 120 kilowatts (kW) through 48 PSUs of 5.5 kW in eight power shelves, according to the NVIDIA DGX user guide. That is why DC Market Insights puts AI rack power at USD 375 per kW of IT load in 2025, against USD 150 per kW for conventional servers, and why AI rack power rises from 40.2% of spending in 2025 to 77.6% in 2035. The next step, 800-volt direct current (800 VDC) power racks, makes 800 VDC Power Racks and Converters the fastest-growing product line, and Middle East and Africa the fastest-growing region at 20.91% a year.

Executive Summary

The Global Data Center Power Supply Unit Market size was valued at USD 3.18 billion in 2020, reached USD 6.07 billion in 2025, and is anticipated to reach USD 21.84 billion by 2035, at a CAGR of 13.66% during the forecast period.

Report attribute	Details
Historical Period	2020-2024
Base Year	2025
Forecast Period	2026-2035
Data Center Power Supply Unit Market Size 2025	USD 6.07 Billion
Data Center Power Supply Unit Market Size 2026	USD 7.12 Billion
Data Center Power Supply Unit Market, CAGR	13.66%
Data Center Power Supply Unit Market Size 2035	USD 21.84 Billion

Data center PSU spending grew 13.79% a year from 2020 to 2025, but the two halves of the market moved very differently. Conventional server, storage and networking PSUs grew from USD 2.87 billion to USD 3.63 billion, while AI rack power shelves went from USD 312.00 million to USD 2.43 billion as accelerator racks moved from 1.04 GW to 6.51 GW of IT load shipped a year. Growth of 13.66% a year to 2035 rests on the AI side: conventional PSUs grow only 3.01% a year because unit prices fall as volumes rise, while AI rack power grows 21.38% a year to USD 16.96 billion. The switch from 54-volt shelves to 800 VDC power racks after 2027 adds content per kW, so the 800 VDC line overtakes the 54-volt shelf line in 2030.

Key Takeaways

Five figures explain where data center PSU spending goes between 2025 and 2035, with the reason behind each.

• The market reaches USD 21.84 billion by 2035, because each kW of AI rack load carries 2.5 times the PSU value of a kW of conventional servers.
• AI rack power rises from 40.2% to 77.6% of spending, because accelerator racks grow from 6.51 GW to 44.47 GW of IT load shipped a year.
• 800 VDC power racks and converters reach USD 14.55 billion in 2035, because NVIDIA ties full-scale 800 VDC production to its Kyber racks in 2027.
• PSUs above 5.5 kW grow 27.58% a year, because 12 kW supplies and 72 kW shelves replace 3 kW server supplies in AI halls.
• Conventional server PSUs grow only 3.01% a year, because European and US efficiency rules already require Titanium-level units and prices keep falling.

What Counts as a Data Center Power Supply Unit?

A data center power supply unit converts facility power into the direct current that servers, storage and network equipment use, and DC Market Insights values these units at USD 6.07 billion in 2025.

Included. Alternating current to direct current (AC-DC) PSUs inside general-purpose servers, mostly in the Common Redundant Power Supply (CRPS) form factor; PSUs in storage arrays and network switches; rack-level power shelves and their hot-swap PSUs for Open Compute Project (OCP) Open Rack V3 (ORv3) and NVIDIA MGX racks at 48 to 54 volts; and 800 VDC or plus/minus 400 VDC power racks (sidecars) with the rack-level DC-DC converters that step 800 volts down for the compute trays. Values are factory prices of the PSU hardware sold to server makers, original design manufacturers (ODMs) and data center operators.

Excluded. Uninterruptible power supply (UPS) systems, covered in the Data Center UPS Market; battery backup units (BBUs) inside power shelves, covered in the Data Center Battery Market; power distribution units (PDUs), busway and switchgear; voltage regulator modules and other board-level converters on the motherboard; power semiconductors sold on their own; and PSUs for personal computers, industrial or telecom equipment outside data centers.

How the segments fit together. Every segment table splits the same USD 6.07 billion of 2025 value. The product-type split is computed directly in the model from conventional and AI shipments; the power-rating and end-user splits divide the same total, and each split sums to the total in every year from 2020 to 2035.

Why Do Data Center Power Supply Unit Market Estimates Differ?

Public estimates for data center power supplies differ because some add UPS systems, PDUs and power semiconductors, while DC Market Insights counts USD 7.12 billion of 2026 spending on PSU hardware only.

Broader definitions add four things. First, facility power equipment such as UPS systems, PDUs and busway, which sit upstream of the PSU and are sized in their own reports. Second, battery backup units, which share the power shelf with the PSUs in many AI racks but store energy instead of converting it. Third, board-level voltage regulators and the gallium nitride (GaN) and silicon carbide (SiC) chips inside PSUs, which would count the same value twice if added to finished PSUs. Fourth, all switched-mode power supplies sold for computing, including desktop and industrial units. Each is a real market, but adding them would blur what a server maker or data center operator pays for the box that turns AC or 800 VDC into the voltage a server uses.

Element	In this market?	Why
Server, storage and network PSUs	Yes (USD 3.63 billion in 2025)	Convert power inside IT equipment
AI rack power shelves (48-54 V)	Yes (USD 2.43 billion in 2025)	Convert power for a whole rack
800 VDC power racks and converters	Yes (USD 13.53 million in 2025)	Convert power for a row of racks
UPS systems and PDUs	No	Facility power equipment
Battery backup units	No	Store energy
Power semiconductors and board-level regulators	No	Components or downstream converters

Buyers inside the scope include hyperscale cloud providers, AI and graphics processing unit (GPU) cloud providers, enterprises and colocation tenants, and telecom and edge operators; servers in small and medium enterprise (SME) server rooms count under enterprise and colocation tenants. UPS systems, PDUs, BBUs, power semiconductors sold on their own and non-data-center PSUs stay outside the scope in every table.

Why Is Data Center PSU Spending Rising So Fast?

Data center PSU spending rises because AI racks carry far more power hardware per kW than general servers, and DC Market Insights expects AI rack power to grow from USD 2.44 billion in 2025 to USD 16.96 billion in 2035.

Rack-Scale NVIDIA Systems Put 48 PSUs in Every Rack

An NVIDIA GB200 NVL72 rack uses six air-cooled 5.5 kW PSUs in each of eight power shelves and consumes about 120 kW, according to the NVIDIA DGX GB200 user guide (revision of September 2026). That is 264 kW of PSU capacity for 120 kW of load, a ratio of 2.2, because each shelf runs with spare supplies. DC Market Insights therefore uses USD 375 of PSU content per kW of AI rack load in 2025, about USD 45,000 per 120 kW rack, against USD 150 per kW for conventional servers. AI racks shipped rise from 6.51 GW of IT load in 2025 to 8.32 GW in 2026.

The NVIDIA 800 VDC Architecture Creates a New Product Line

NVIDIA said in May 2025 that full-scale production of 800 VDC data centers will coincide with its Kyber rack-scale systems in 2027, and that the design improves end-to-end efficiency by up to 5% and cuts maintenance costs by up to 70%, according to its technical blog of 20 May 2025. NVIDIA named Delta, Flex, LITEON and Megmeet among its power component partners in October 2025. DC Market Insights models 800 VDC power racks and converters at USD 78.18 million in 2026, USD 822.41 million in 2027 and USD 6.17 billion in 2030, as their share of AI rack shipments rises from 2% to 60%.

Delta, Lite-On and Advanced Energy Report AI Power Growth

Delta Electronics reported record second-quarter 2026 revenue of NT$183.2 billion, up 48%, with Power Electronics revenue up 50%, and said that data center-related business made up more than half of its first-half revenue, according to its July 2026 results call. Advanced Energy reported Data Center Computing revenue of USD 587.3 million for 2025, up 107%, according to its results filed with the Securities and Exchange Commission (SEC) on 10 February 2026. Lite-On Technology said its Cloud and AIoT business grew more than 30% in 2025 and expects AI-related revenue to exceed 30% of the total in 2026. These results support the 17.2% rise DC Market Insights models from 2025 to 2026.

How Are Data Center PSU Designs Changing?

PSU ratings are rising from 3 kW to 5.5 kW and 12 kW per unit, and units above 5.5 kW grow from 17.0% of 2025 value to 54.0% in 2035 in the DC Market Insights model.

From 33 kW to 72 kW Power Shelves in the OCP Open Rack

A standard ORv3 power shelf holds six 5.5 kW PSUs for a maximum of 33 kW at above 97.5% efficiency, according to the Delta product listing on the OCP marketplace. The OCP Open Rack V3 High Power Rack (HPR) V2 specification, revision 1.0.0 of June 2026, doubles the PSU to 12 kW and the shelf to 72 kW, or 60 kW with one spare supply and dual cords. Shelves at this rating serve 100 kW to 200 kW racks without moving to 800 VDC, which keeps the 54-volt shelf line at USD 4.26 billion in 2027 before it gives way to 800 VDC racks.

Gallium Nitride and Silicon Carbide Raise Power Density

Navitas Semiconductor showed a 12 kW PSU for AI data centers and said in May 2025 that NVIDIA had selected it for the 800 VDC architecture. Infineon Technologies expects revenue from AI data center power of around EUR 2.5 billion in fiscal year 2027, up from around EUR 1.5 billion in fiscal 2026, according to its February 2026 release. Wide-bandgap chips let a 12 kW supply fit in the slot of a 5.5 kW unit, which is why DC Market Insights expects PSU prices per watt to fall from USD 0.13 in 2025 to USD 0.10 in 2035 while value per rack rises.

Power Makers Separate Their Data Center Businesses

Flex announced on 5 May 2026 that it intends to spin off its Cloud and Power Infrastructure segment and targets about 65% to 75% revenue growth for that business in fiscal 2027. Vertiv scheduled its 800 VDC power portfolio for the second half of 2026. Specialised data center power businesses can price and invest for AI racks rather than for broad industrial demand; the AI and GPU cloud provider segment grows fastest among buyers at 20.20% a year.

Market Restraints: What Limits Data Center PSU Growth?

Falling prices for conventional PSUs and uncertain 800 VDC timing restrain the market, and the DC Market Insights low case of USD 17.52 billion in 2035 shows the effect of a slower AI rack ramp.

Titanium Efficiency Is Already the Legal Floor for Servers

The European Union (EU) ecodesign rule for servers, Regulation (EU) 2019/424, has required single-output server PSUs to reach 90%, 94%, 96% and 91% efficiency at 10%, 20%, 50% and 100% load since 1 January 2023. The US ENERGY STAR Computer Servers Version 4.0 sets the same levels for supplies of 750 watts or more from 12 January 2024. With Titanium-level units already standard, buyers no longer pay a premium to upgrade efficiency, which holds conventional server PSUs to 3.01% a year, from USD 2.83 billion in 2025 to USD 3.81 billion in 2035.

800 VDC Volume Depends on Rack Launch Dates

Delta said in July 2026 that it would begin mass production of plus/minus 400 V and 800 V products in the third quarter of 2026, with meaningful volume next year, while Advanced Energy expects initial 800 V production revenue in late 2027 and a larger ramp in 2028, according to its August 2026 results call. A delay of one rack generation would cut 2028 spending sharply, since DC Market Insights puts 800 VDC at USD 2.48 billion that year. The low case assumes AI rack shipments 20% lower and prices 5% lower from 2027.

Where Are the Openings for Data Center PSU Suppliers?

The largest openings are 800 VDC power racks and AI campuses in the Gulf and India, worth USD 14.55 billion and USD 1.26 billion of 2035 value in the DC Market Insights model.

Sidecar Power Racks for 800 VDC Rows

Delta has shown a 1.1 megawatt (MW)-class in-row power rack that converts 400 to 480 volts AC into 800 VDC, and Lite-On said its 800 VDC power rack is in testing. At DC Market Insights content of USD 470 per kW in 2026, one 1.1 MW power rack with its downstream converters carries about USD 0.52 million of PSU hardware. The line grows from USD 13.53 million in 2025 to USD 14.55 billion in 2035, 66.6% of the market.

Gulf and Indian AI Campuses

Saudi Arabia grows from USD 60.71 million in 2025 to USD 502.27 million in 2035, 23.53% a year, and India from USD 121.43 million to USD 753.41 million, 20.02% a year. Both countries add AI capacity with rack-scale systems from the first hall and have a small installed base of older servers, which lifts growth above the 13.66% global rate.

How Much Does a Data Center Power Supply Cost per kW?

Data center PSU hardware costs about USD 150 per kW of IT load for conventional servers and USD 375 per kW for AI rack power shelves in 2025, according to DC Market Insights unit values.

Year	Conventional servers (USD per kW of IT load)	AI rack power shelves (USD per kW)	800 VDC racks and converters (USD per kW)	Typical PSU price (USD per watt of rating)
2020	165	300	Not shipped	0.15
2025	150	375	520 (pilot units)	0.13
2030	140	400	430	0.11
2035	132	360	385	0.10

No PSU maker publishes a price list, so these are DC Market Insights estimates built from rack designs. A GB200 NVL72 rack carries 264 kW of PSU rating for 120 kW of load, and a conventional server carries two redundant supplies rated at two to three times its draw. Advanced Energy said in August 2026 that 800 V racks are an opportunity to increase its content per rack, and Navitas puts power semiconductor content at about USD 55 per kW of GPU power in 2026, roughly one-seventh of the AI shelf price per kW.

Which Standards and Rules Apply to Data Center PSUs?

Six rules and specifications shape USD 6.07 billion of 2025 PSU spending, from EU efficiency law to OCP rack designs.

• Regulation (EU) 2019/424: ecodesign rule for servers and data storage; PSU efficiency of 90/94/96/91% at 10/20/50/100% load and power factor 0.95 at 50% load since 1 January 2023.
• ENERGY STAR Computer Servers Version 4.0: effective 12 January 2024; the same efficiency levels for single-output PSUs of 750 watts or more.
• 80 PLUS Titanium: the certification run by CLEAResult; 90/94/96/91% for 230-volt and 277-volt redundant data center PSUs.
• OCP Open Rack V3 power shelf specifications: 33 kW shelves with six 5.5 kW PSUs and the HPR V2 72 kW shelf with six 12 kW PSUs (revision 1.0.0, June 2026).
• NVIDIA 800 VDC architecture: published May 2025 and extended at the OCP Global Summit in October 2025; full-scale production with Kyber racks in 2027.
• IEC 62368-1: the International Electrotechnical Commission safety standard for information and communication technology equipment, which every data center PSU must pass.

Which Product Types Lead Data Center PSU Spending?

Conventional server PSUs lead with 46.6% of 2025 value, and 800 VDC power racks and converters become the largest product type by 2035 with 66.6%, according to DC Market Insights.

By Product Type: Conventional Server PSUs Lead with 46.6%

Product type	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
Conventional Server PSUs	2,829.84	46.6%	3,808.25	3.01%
Storage and Networking PSUs	798.16	13.1%	1,074.12	3.01%
AI Rack Power Shelves at 48-54 V	2,429.84	40.0%	2,401.59	-0.12%
800 VDC Power Racks and Converters	13.53	0.2%	14,554.08	100.98%
Total	6,071.37	100.0%	21,838.04	13.66%

By Power Rating: PSUs Below 2 kW Lead with 52.0%

PSU power rating	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
Below 2 kW	3,157.11	52.0%	4,804.37	4.29%
2 kW to 5.5 kW	1,882.12	31.0%	5,241.13	10.78%

DC Exclusive: AI Rack Power Content Teardown — From USD 150 to USD 470 of PSU Hardware per kW

DC Market Insights built this teardown from 9 inputs taken from NVIDIA and OCP documents, supplier statements and its own unit values; it is a modelled estimate of the PSU hardware each rack design carries per kW of IT load.

Rack design	PSU configuration	PSU rating per kW of load	PSU content, 2025 or first year	Source of configuration
Conventional server rack	Two redundant 1.6 kW CRPS units per server	2.0 to 3.0	USD 150 per kW	DC Market Insights unit value
ORv3 rack, 33 kW shelf	Six 5.5 kW PSUs, 27.5 kW with one spare	1.2 per shelf	USD 300 to 350 per kW	OCP marketplace listing
GB200 NVL72 rack, about 120 kW	Eight shelves of six 5.5 kW PSUs (264 kW)	2.2	USD 375 per kW, about USD 45,000 per rack	NVIDIA DGX user guide
HPR V2 rack, 72 kW shelf	Six 12 kW PSUs, 60 kW with one spare and dual cords	1.2 per shelf	USD 400 per kW (2030)	OCP HPR V2 specification
800 VDC row with in-row power rack	1.1 MW-class AC to 800 VDC rack plus DC-DC converters	About 1.2	USD 470 per kW (2026)	Delta product release; DC Market Insights

The teardown shows why PSU spending grows faster than server shipments. A kW of AI load carries 2.5 times the PSU value of a kW of general servers because of redundancy across shelves and the higher price of 5.5 kW and 12 kW units. The 800 VDC row adds another step, about USD 470 per kW in 2026, because conversion moves into a dedicated rack and a second converter stage in each compute tray. As volumes grow, the price per kW falls to USD 385 by 2035, but it stays above the 54-volt shelf.

Which Region Spends the Most on Data Center PSUs?

North America leads with 46.0% of 2025 value, or USD 2.79 billion, and Middle East and Africa is the fastest-growing region at 20.91% a year. Regions are counted where the equipment is installed, not where the PSU is made.

North America Leads with 46.0% Share

North American PSU spending rises from USD 2.79 billion in 2025 to USD 10.15 billion in 2035, a CAGR of 13.78%. The region installs the largest number of NVIDIA rack-scale systems, and its hyperscale and AI cloud campuses are expected to run the first 800 VDC rows from 2027.

Asia Pacific Holds 32.0% Share

Asia Pacific grows from USD 1.94 billion to USD 6.88 billion, 13.48% a year. China accounts for USD 789.28 million in 2025, mostly from domestic server makers and suppliers such as Great Wall Power and Huawei Digital Power, while Taiwan hosts the factories of Delta, Lite-On, Chicony Power and AcBel Polytech that ship to the rest of the world.

Europe Holds 14.5% Share

Europe grows from USD 880.35 million to USD 2.40 billion, 10.56% a year, the slowest of the five regions. Germany, the United Kingdom and France have large conventional server bases already at Titanium efficiency under Regulation (EU) 2019/424, so fewer new AI racks per installed kW hold back growth.

Middle East and Africa Is the Fastest-Growing Region at 20.91%

Middle East and Africa grows from USD 212.50 million to USD 1.42 billion as Saudi Arabia and the United Arab Emirates (UAE) build AI campuses with rack-scale systems from the first hall.

Latin America Holds 4.0% Share

Latin America grows from USD 242.85 million to USD 982.71 million, 15.00% a year, led by Brazil and Mexico, where cloud regions and colocation halls add AI racks.

Which Countries Spend the Most on Data Center PSUs?

The United States spends USD 2.52 billion on data center PSUs in 2025, 41.5% of the global total, and Saudi Arabia is the fastest-growing country in the top 12 at 23.53% a year.

Rank	Country	2025 (USD million)	2035 (USD million)	CAGR 2025-2035	Region
1	United States	2,519.62	9,171.98	13.79%	North America
2	China	789.28	2,511.37	12.27%	Asia Pacific
3	Japan	218.57	742.49	13.01%	Asia Pacific
4	Germany	200.36	524.11	10.09%	Europe
5	United Kingdom	194.28	545.95	10.88%	Europe
6	Canada	157.86	611.47	14.50%	North America
7	India	121.43	753.41	20.02%	Asia Pacific
8	Australia	121.43	436.76	13.66%	Asia Pacific
9	South Korea	115.36	447.68	14.52%	Asia Pacific
10	France	109.28	283.89	10.02%	Europe
11	Brazil	97.14	414.92	15.63%	Latin America
12	Saudi Arabia	60.71	502.27	23.53%	Middle East and Africa

The United States stays the largest buyer through 2035, with its share rising slightly to 42.0% as AI racks concentrate there. India, at 20.02% a year, is the fastest-growing large country after Saudi Arabia, because new Indian AI capacity starts with high-rating shelves (DC Market Insights allocation).

How Could the 2035 Data Center PSU Forecast Change?

The 2035 market ranges from USD 17.52 billion to USD 25.60 billion around the USD 21.84 billion base case, depending on AI rack shipments and PSU prices from 2027.

Scenario	2035 (USD million)	CAGR 2025-2035	Assumption
Low	17,524.56	11.18%	AI rack shipments 20% lower and PSU prices 5% lower from 2027
Base	21,838.04	13.66%	Model as described
High	25,600.46	15.48%	AI rack shipments 15% higher and PSU prices 5% higher from 2027

The low case follows a later 800 VDC ramp, in line with the late-2027 start Advanced Energy describes; the high case follows faster adoption of 12 kW supplies and 800 VDC rows, in line with the third-quarter 2026 production start Delta describes.

Who Are the Leading Data Center Power Supply Companies?

Delta Electronics leads with about 33% of 2025 value, and the top five suppliers hold about 74% (DC Market Insights assessment based on supplier results and named rack designs).

• Delta Electronics
• Lite-On Technology
• Advanced Energy Industries (Artesyn)

Methodology: How DC Market Insights Sizes the Data Center Power Supply Unit Market

DC Market Insights sizes the market as IT load shipped each year multiplied by PSU content per kW, which gives USD 6.07 billion in 2025 and USD 21.84 billion in 2035.

The model in numbers: new data center IT capacity of 12.0 GW in 2025, 22 GW in 2030 and 27 GW in 2035, with an AI share of 35%, 60% and 66%; conventional IT load shipped equals new conventional capacity plus one-sixth of the installed conventional base for server refresh (24.19 GW in 2025, 36.99 GW in 2035); AI load shipped equals new AI capacity plus 22% of the installed AI base (6.51 GW in 2025, 44.47 GW in 2035). Content per kW is USD 150 for conventional equipment in 2025 (22% of it storage and networking), USD 375 for 54-volt AI shelves and USD 470 for 800 VDC racks in 2026, with the 800 VDC share of AI shipments rising from 0.4% in 2025 to 60% in 2030 and 85% in 2035. The same capacity and refresh logic is used in the Server Chassis Market, and the power path upstream of the PSU is sized in the Data Center Busway Market.

Three bound checks test the result. Ceiling one: USD 6.07 billion is 1.1% of the USD 570.04 billion DC Market Insights estimate of total 2025 data center infrastructure spend, in line with a component that is a small part of each server. Ceiling two: at power semiconductor content of 15% to 25% of the PSU price, the USD 3.32 billion of 2026 AI rack power implies USD 0.5 billion to USD 0.8 billion of chips, below the around EUR 1.5 billion Infineon alone expects from AI data center power in fiscal 2026. Floor: Advanced Energy’s Data Center Computing revenue of USD 587.3 million covers 9.7% of the 2025 market from the third-largest supplier.
