ATX Power Supply Manufacturer | 20+ Years B2B OEM/ODM

A computer power supply is a critical electronic component that bridges the mains grid and computing hardware, converting unregulated AC power into the stable DC power required for the precise operation of various computer parts, and its technical design and manufacturing quality are key factors affecting the user experience and hardware durability of computing equipment. Shenzhen Yijian Technology Co., Ltd., a leading OEM manufacturer of PC power supplies with a focus on specialization and professionalism, has built a modern production base of 20,000 square meters with over 500 skilled workers, dedicated to the mass production of high-quality computer power supplies with a monthly capacity of 300,000 units, capable of meeting the large-volume procurement needs of global distributors, computer manufacturers and enterprise customers. Yijian’s computer power supply products feature a rational internal structure design, with high-quality electronic components such as Japanese solid capacitors and high-temperature resistant transformers selected for core parts, which significantly improve the product’s service life and stability, and reduce the failure rate during long-term use. The company’s R&D team pays close attention to the latest technological trends and market demands in the computer industry, and timely optimizes and upgrades computer power supply products to adapt to the development of new hardware such as the latest generation of CPUs and PCI-E 5.0 GPUs. For example, aiming at the high peak power demand of modern high-performance graphics cards, the team has upgraded the transient response circuit of computer power supplies, shortening the response time to power load changes and ensuring that the power supply can instantly provide sufficient energy to meet the hardware’s peak demand without voltage fluctuations. Yijian implements a multi-layered quality inspection system for computer power supplies, with the IQC team conducting strict electrical performance and appearance inspections on all incoming raw materials and components to ensure that they meet the company’s high production standards; the in-process QC team inspects the welding quality, component installation accuracy and wire connection reliability of each semi-finished product during the assembly process, preventing defective semi-finished products from entering the next process; the final QC team conducts a comprehensive performance test on each finished computer power supply, including no-load test, load test, short-circuit test and electromagnetic interference test, only delivering products that pass all tests to the market. All computer power supplies from Yijian have obtained international authoritative certifications, which not only prove the product’s compliance with global technical and safety standards but also facilitate the company’s product export to more than 20 countries and regions including the United States, Europe, Japan, South Korea and Russia. The company’s computer power supply products are divided into different series according to application scenarios, including the gaming series, server series, office series and industrial control series, each with targeted performance optimizations. The gaming series computer power supplies, such as the 80Plus Gold GTJ-850W model, adopt a full-modular design that allows users to customize cable configurations, reducing cable clutter in the chassis and improving heat dissipation efficiency, while the single +12V rail design delivers high current output to support the high-power needs of gaming hardware; the office series computer power supplies focus on low noise and energy efficiency, providing a quiet and energy-saving working environment for office computers; the server series computer power supplies, such as the 80Plus Bronze BF-550W model, are designed for 24/7 continuous operation with strong anti-interference capabilities, adapting to the complex electromagnetic environment of computer rooms. Yijian attaches great importance to the after-sales service of computer power supplies, and has formulated a complete after-sales service process to ensure that customer problems are solved efficiently. The company provides 1% spare parts for each order, which can be used for the urgent replacement of damaged parts, minimizing the downtime of customer equipment; after receiving customer feedback, the sales team responds within 2 hours to understand the specific problem, and all relevant departments jointly formulate a detailed 8D report within 24 hours, analyzing the root cause of the problem and proposing feasible solutions, and communicating fully with customers to confirm the solution and ensure its effective implementation. As a National High-tech Enterprise and Shenzhen Specialized and New Enterprise, Yijian has always adhered to the path of scientific and technological innovation oriented by people, and has obtained more than 20 appearance design patents for its computer power supply products, in addition to more than 100 professional certifications, combining aesthetic design with practical performance to meet the diverse needs of the market. The company’s unswerving pursuit of unity, innovation, pragmatism and progress has made its computer power supply products gain a good reputation in the global market, and Yijian is committed to complementing the advantages of various industries and creating brilliance together with global partners.
