The PC power supply industry is currently experiencing a situation where structural benefits coexist with industry reshuffling. The high-end and technological upgrade sectors will witness growth benefits, while the low-end homogeneous market will face a winter-like competitive elimination. The overall industry maintains steady growth but with increased differentiation. At the same time, the PC power supply industry as a whole will exhibit a development trend of "stable total growth and structural upgrading". Although the growth of the traditional consumer market has slowed down, mid-to-high-end products, emerging scenarios, and technological innovations will open up new growth spaces. The industry is shifting from "quantitative expansion" to "qualitative improvement", and its future prospects are concentrated in three dimensions: market structure, technological evolution, and scenario expansion. 

I. Market Landscape: Concentration Increases, Structural Growth Becomes Dominant 

The overall scale has been steadily increasing, with significant differentiation in various market segments. In 2024, the market size of PC power supplies in China reached 34.3 billion yuan. It is expected that the average annual compound growth rate from 2025 to 2030 will be approximately 7.8%. Among them, the proportion of low-end power supplies below 500W has been decreasing year by year, while the market share of high-end power supplies ranging from 750W to 1200W has risen from 17.5% in 2023 to 21.3% in 2024. The sales of products of 850W and above increased by 19.3% in 2024, becoming a core growth driver. Although the global market is affected by the traditional PC shipment volume, it is expected that the compound annual growth rate from 2025 to 2031 will be -1.5%, but high-efficiency and high-power products will still maintain positive growth. 

The concentration of the industry continues to increase. Policies and technical barriers accelerate the elimination of small and medium-sized manufacturers. In 2024, the number of active domestic PC power supply brands will decrease by approximately 32% compared to 2020. The industry's CR5 (market share of the top five enterprises) has risen from 32.5% in 2020 to 38.7% in 2023. Leading enterprises such as HAJIA, CHENGANG, and TAI DA have occupied over 50% of the domestic market share by leveraging their technological accumulation and supply chain advantages. However, if small and medium-sized manufacturers fail to break through the energy efficiency certification and cost bottlenecks, they will face the risk of being integrated or eliminated. 

II. Technological Evolution: High efficiency, miniaturization, and intelligence become the core directions 

The upgrade of energy efficiency standards has forced technological innovation. The new version of "Limits and Energy Efficiency Grades for Computer Switching Power Supplies" in China includes the 80PLUS gold-level energy efficiency as a mandatory reference. The new EU Ecodesign Lot 3 regulations require the standby power consumption to be lower than 0.5W, which has driven a general increase in industry conversion efficiency to over 90%. The penetration rate of Titanium Gold-certified products will increase from 18% in 2023 to 40% in 2030. Leading enterprises have launched flagship products with conversion efficiency approaching 95%, meeting the demands for green and energy-efficient operations. 

New materials and new forms expand product boundaries. Widespread bandgap semiconductors such as gallium nitride (GaN) and silicon carbide (SiC) have begun to be piloted for application. After adopting GaN components, the DPS series power supplies launched by Delta have significantly increased power density, and the proportion of single path + 12V output exceeds 95%, meeting the power supply requirements for high-end GPUs. At the same time, the SFX miniaturized power supplies have a penetration rate of 29.4% in the mini computer market. The liquid cooling power supply interface standard will be upgraded to an industry standard in 2025, further promoting product form innovation. 

Intelligent functions are gradually becoming widespread. Digital power modules have begun to integrate the PMbus communication protocol, enabling remote monitoring of voltage and current status. Some products also come equipped with intelligent temperature control algorithms, allowing for dynamic power consumption adjustment and fault prediction, meeting the intelligent management requirements for scenarios such as AI PCs and workstations. 

III. Scene Expansion: From Consumer Level to Commercial Level, New Scenarios Open Up Additional Growth Space 

Consumer market: Esports and high-performance PCs become the main force. The popularity of esports PCs and content creation consoles has driven the growth in demand for modular, low-noise, high-power power supplies. Products with 80PLUS Gold or higher certification have become standard equipment for mid-to-high-end esports consoles, and the shipment volume of such products has exceeded 60% by 2024. 

Commercial and emerging scenarios: AI PCs and servers bring new opportunities. AI PCs and edge computing devices have higher requirements for instantaneous peak power and stability of power supply. The explosion of the server power supply market has also driven traditional PC power supply enterprises to make cross-border layouts - the market size of server power supply (including AI servers) in China is expected to reach 34.3 billion yuan in 2025, with a compound growth rate of over 150%. Companies like Hengjia and Great Wall have begun to develop server-level PC power supplies, achieving cross-scenario technical collaboration. In addition, the domestic demand for integrated machines in the information security field also drives the research and development of dedicated power supply solutions. Great Wall Technology has established an information security power supply R&D center in Wuhan, focusing on low-power consumption and high-security products. 

In conclusion, the development prospects of the PC power supply industry are influenced by a variety of factors, including market demand, technological progress, competitive landscape, and policy environment, etc.
