ATX Power Supply Manufacturer | 80Plus Gold/Platinum & ATX3.1

ATX power supply, as a standardized power supply solution for computing equipment, has become the cornerstone of desktop and server power supply systems due to its standardized interface, stable voltage output and scalable power design. Shenzhen Yijian Technology Co., Ltd., a national high-tech enterprise and a Shenzhen specialized and new enterprise, has focused on the innovation and manufacturing of ATX power supplies for many years, integrating R&D, design, production and sales, and building a complete product system that covers low, medium and high power levels and adapts to various application scenarios. Yijian’s R&D team has more than 20 members, all with over 10 years of experience in ATX power supply design, and has a deep grasp of the technical evolution of ATX specifications from ATX 12V 1.0 to ATX 3.0. The team optimizes the power factor correction (PFC) circuit and resonant conversion technology of ATX power supplies, improving the power factor to more than 0.95 and the conversion efficiency to reach the 80Plus Platinum level, which not only reduces energy consumption but also decreases heat generation, extending the service life of the product. The ATX power supply products of Yijian adopt high-quality electronic components such as Japanese capacitors, with built-in perfect protection functions including over-voltage, over-current, over-temperature, short-circuit and under-voltage protection, which can effectively protect the connected computing equipment from power supply abnormalities. The factory of Yijian has passed ISO9001 quality management system certification and ISO14001 environmental management system certification, and implements a full-process quality control system for ATX power supply production. The IQC team conducts strict inspection on all raw materials such as capacitors, inductors and PCBs to ensure that the incoming materials meet the production standards; 2-3 QC personnel are assigned after each production process to inspect the welding quality, component installation and interface accuracy of ATX power supplies; each finished product must pass aging tests, high and low temperature tests and electromagnetic compatibility tests to ensure stable performance in complex working environments. Yijian’s ATX power supplies have a variety of structural designs, including non-modular and full-modular types. The full-modular ATX power supply features detachable cables, which allows users to select the required cables according to the actual hardware configuration, reducing cable clutter in the chassis and improving heat dissipation efficiency, which is especially suitable for high-performance desktops and custom-built servers. The 80Plus Platinum AI-3000W full-modular ATX power supply, a flagship product of Yijian, was showcased at COMPUTEX 2025 and received high attention from the industry. This product is designed for high-power server clusters and professional workstations, with a dual +12V output design that meets the ATX 3.0 standard, supporting the instantaneous high-power demand of high-end hardware, and its conversion efficiency of more than 92% can greatly reduce the operating cost of large-scale computing equipment. The 80Plus Gold GN-1300W full-modular ATX power supply is suitable for high-end gaming desktops and professional design workstations, with multiple PCI-E 6+2pin interfaces to support multiple graphics card configurations, and stable voltage output to ensure the smooth operation of 3D modeling, video editing and other resource-intensive software. Yijian has a perfect after-sales service system for ATX power supplies, providing technical support and maintenance services for global customers. The company promises to respond to customer inquiries and feedback within 2 hours, and form a cross-departmental solution team to issue an 8D report within 24 hours, analyzing the root cause of the problem and providing targeted solutions. With its strong technical strength, advanced production equipment and strict quality control, Yijian’s ATX power supplies have obtained more than 100 domestic and foreign certifications and patents, and are exported to more than 20 countries and regions including Japan, South Korea, Canada, Mexico and the Middle East, becoming a reliable supplier of ATX power supplies for global computing equipment manufacturers and end users.
