GPU Power Supply Unit (PSU) Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global GPU Power Supply Unit (PSU) Market Trends and Insights

Surge in AI-Driven Data Centers

Hyperscalers committed USD 103 billion in 2026 capital expenditures to support 4.5 gigawatts of contracted capacity and a further 9 gigawatts in pipeline projects, accelerating grid interconnection timelines from 36 months to 18 months.^{[1]Duke Energy, “Duke Energy Announces Major Expansion Plans to Meet Growing Energy Needs,” duke-energy.com} NVIDIA GB200 NVL72 racks now draw 120-140 kilowatts per cabinet, compelling PSU vendors to move from 1-2 kilowatt designs to modular 5-10 kilowatt units that couple directly with liquid manifolds. Retrofit economics favor greenfield builds because upgrading a legacy 10-megawatt site to AI densities costs operators USD 3-4 million per facility, compared with USD 16 million for a new build that avoids thermal trade-offs. Vendors are staging inventory near hyperscaler construction clusters in Virginia, Texas, and Singapore to secure a first-mover advantage, and Delta Electronics disclosed that AI-related PSUs accounted for 50% of its server-PSU revenue in Q4 2025.

Rapid Adoption of GPU-Based High-Performance Computing

Enterprise HPC clusters are mirroring hyperscaler architectures as firms deploy on-premises inference servers to avoid cloud egress costs. Dell’s PowerEdge XE7745, launched in July 2025, integrates a 3,200-watt 80 PLUS Titanium PSU tailored for dual-GPU boards. Test-time compute scaling lifted per-query energy from 0.34 Wh to 4.32 Wh, forcing enterprises to double PSU capacity without increasing GPU count.^{[2]Scaling Test-Time Compute Team, “Scaling Test-Time Compute Optimally Can Be More Effective Than Scaling Model Parameters,” arxiv.org} Flex Ltd backed the trend by adding 1.134 million ft² of capacity across Dallas, Colombia, and Poland in 2025, shortening lead times for custom orders. The convergence of cloud and enterprise specifications is compressing design cycles to 12 months, encouraging vendors to develop interoperable platforms that satisfy both Open Compute Project and proprietary racks.

Growing Demand for Liquid-Cooled Rack Architectures

Air-cooled PSUs top out near 5 kilowatts because heat flux beyond 200 W cm² drives MOSFET junctions above 85 °C, eroding reliability. Vertiv and CoolIT introduced cold-plate PSUs that deliver 10-12 kilowatts while keeping junction temperatures below 70 °C, doubling the mean time between failures to 100,000 hours. Lite-On Technology went further, unveiling 110-kilowatt liquid-cooled power shelves for Nvidia’s Vera Rubin Observatory in 2025. Hyperscalers now prefer integrated power-and-cooling shelves from a single vendor to simplify rack assembly and warranty scopes, creating white space for suppliers that master computational fluid-dynamics modeling alongside power electronics.

Integration of Digital Twin-Enabled PSU Monitoring

Fraunhofer ISIT’s thermal digital twin, released in 2025, predicts gallium nitride MOSFET degradation 72 hours before failure, enabling 5-year warranties. Hyperscalers quantify downtime risk at USD 100,000-500,000 per multi-hour outage, so predictive telemetry is migrating from optional feature to qualification prerequisite. Delta Electronics embedded the framework into its 800-V direct-current PSU line, commanding a 15-20% price premium. Procurement guidelines now mandate open APIs that plug PSU data into rack orchestration stacks, elevating software capability as a hard requirement when awarding design wins.

Supply Chain Volatility in Gallium Nitride Components

China controls 98% of global gallium output, and 2024 export curbs doubled spot prices to USD 2,100 kg-¹, inflating BOM costs for high-power PSUs. Innoscience scaled wafer fabrication to 15,000 eight-inch units per month at 97% yields, locking in deals with Google but exposing non-Chinese vendors to sudden embargo risk. Western suppliers are co-funding gallium-nitride epi-lines in Europe and North America, but commercial scale remains two to three years away, maintaining price volatility through 2027.

Thermal Management Challenges Above 5 kW Output

Heat flux over 200 W cm² pushes gallium-nitride MOSFETs to 150 °C, trimming switching efficiency by 30% within 10,000 hours. Cold-plate integration adds USD 150-200 per PSU and extends design cycles to 18 months, restricting adoption to hyperscalers that can amortize the incremental cost across hundreds of racks. Navitas Semiconductor’s 12-kilowatt reference design achieves 97.8% efficiency but requires 48 V rack backplanes, which are incompatible with legacy 12 V infrastructure.

Segment Analysis

By Output Power Rating: Gallium Nitride Enables Multi-Kilowatt Designs

The 2-3 kilowatt category accounted for 42% of GPU power supply unit market revenue in 2025, underscoring its fit with existing 208/240 V power distribution and air cooling. Units above 5 kilowatts, however, are forecast to grow at a 20.04% CAGR through 2031 as hyperscalers standardize on 48 V backplanes and liquid manifolds to handle higher thermal loads. Navitas Semiconductor’s 12-kilowatt blueprint validated 97.8% efficiency, establishing an aspirational ceiling for vendors still limited to 3.3-kilowatt silicon designs.^{[3]Navitas Semiconductor, “GaN Power ICs Enable 12 kW Server PSU,” navitassemi.com} 

Enterprises upgrading inference clusters gravitate toward 3-5 kilowatt PSUs because they align with dual-GPU servers like Dell’s PowerEdge XE7745. The GPU power supply unit market for the above-5-kilowatt tier is concentrated in North America, whereas Asia-Pacific data centers are retrofitting 2-3 kilowatt units to postpone capex. Certification costs under 80 PLUS Titanium, running USD 3,500-8,000 per SKU, delay launches in the highest-power bands, and disproportionately burden smaller vendors.

By Form Factor: Custom Designs Outpace CRPS

Common redundant power supply units (PSUs) maintained a significant 45% market share in 2025. This dominance is attributed to enterprise buyers' preference for vendor-agnostic spare parts, which offer flexibility and compatibility across various systems. However, proprietary and hyperscaler-specific PSU layouts are experiencing rapid growth, with a compound annual growth rate (CAGR) of 19.46%. Delta Electronics reported that customized boards accounted for 50% of its server-PSU revenue during the fourth quarter of 2025, highlighting the increasing demand for tailored solutions. Meanwhile, the GPU power supply unit market associated with Open Compute Project (OCP) specifications is witnessing a decline. This is due to the inability of OCP thermal envelopes to meet the rising demand for 120-140 kilowatt rack targets, which are becoming the industry standard.

Hyperscalers are now actively collaborating with manufacturers to co-design power shelves that incorporate advanced features such as digital twin telemetry, liquid-convergence plates, and 800-volt direct current inputs. These features are not present in standard common redundant power supplies (CRPS), making them a key differentiator in the market. For instance, Lite-On’s development of a 110-kilowatt power shelf for Nvidia exemplifies the level of customization that has become essential in meeting hyperscaler requirements. This trend underscores the need for vendors to adopt dual roadmaps. On one hand, they must continue to produce standardized units to cater to enterprise refresh cycles. On the other hand, they are required to develop bespoke stock-keeping units (SKUs) that are updated every 6-9 months to align with the frequent revisions and evolving demands of hyperscalers.

By End Application: Inference Servers Drive Distributed Demand

GPU accelerator servers accounted for 56% of 2025 shipments, maintaining their dominance in the market. However, inference appliances are experiencing faster growth, with a compound annual growth rate (CAGR) of 19.39%, as production workloads increasingly surpass training cycles. According to Microsoft Research, energy consumption per inference has increased twelvefold, driving the need for more frequent PSU refreshes. The GPU power supply unit market share associated with inference gear is concentrated around 2-3 kilowatts, which represents an optimal range that balances air cooling requirements with performance efficiency.

High-performance computing (HPC) allocations have reached a plateau as budgets are being redirected toward commercial AI applications. This shift has resulted in a reduction in incremental PSU orders from research laboratories. Meanwhile, edge deployments are driving greater diversity in volume requirements, creating opportunities for suppliers with extensive logistics capabilities rather than those focused solely on hyperscaler clients. FuriosaAI’s RNGD Server, launched in September 2025 with a 3-kilowatt chassis, exemplifies power envelopes optimized for inference workloads, highlighting the growing demand for such specialized solutions.

Geography Analysis

Asia-Pacific retained 63% revenue share in 2025, anchored by Taiwan’s vertically integrated supply chain, where Delta Electronics, Lite-On Technology, and FSP Group collectively exceed 40% global output. Delta’s Q4 2025 sales reached NTD 161.61 billion (USD 5.11 billion) with AI PSUs contributing 50% of server-power turnover. Innoscience’s gallium nitride wafer-scale production secures priority access to raw materials, enabling Taiwanese assemblers to quote shorter lead times than their Western peers. Yet margin pressure is mounting as hyperscalers move design work in-house, relegating OEMs to build-to-print roles.

North America is projected to grow at a compound annual growth rate (CAGR) of 19.96% due to significant investments and developments by hyperscalers. These companies currently have 35 gigawatts of capacity under construction and have entered into a 10.5-gigawatt clean-energy agreement with Brookfield, which will span from 2026 to 2030.^{[4]JLL, “Data Center Outlook 2026,” jll.com} Additionally, Duke Energy has allocated USD 103 billion to grid upgrades to accommodate increasing energy demand driven by artificial intelligence (AI) applications. Flex Ltd expanded its U.S. operations in 2025 by adding 534,000 square feet of manufacturing space, addressing the growing preference for localized production to mitigate geopolitical risks and ensure supply chain resilience.

Europe and South America are experiencing slower growth than North America, primarily due to fewer hyperscale campuses and stricter environmental permitting regulations. However, Europe’s Ecodesign Directive is driving the adoption of 80 PLUS Titanium power supply units (PSUs), which are more energy-efficient and environmentally friendly. In contrast, the Middle East and Africa regions remain in the early stages of development, constrained by limited grid capacity and a heavy reliance on imported components. Despite these challenges, sovereign AI initiatives in countries like Saudi Arabia and the United Arab Emirates are fostering the establishment of first-wave data centers, signaling the beginning of growth in these regions.
