The MES system achieves full-process traceability of power supply units, recording every production step, quality check and product detail in real time. This data-driven approach provides valuable insights for production optimization, quality control and after-sales service, enhancing the overall operational efficiency of the enterprise. All power supply units produced by Yijian undergo stringent quality testing and hold a comprehensive range of international certifications, including UL, EAC, FCC, CE, CCC, RoHS, TUV, 3C, CB, KC, CSA and C-TICK. These certifications validate that Yijian’s PSUs comply with the strict technical, safety and environmental regulations of different countries and regions, enabling seamless market access across the globe. The company’s power supply unit product line is diverse, spanning power ratings from 550W to 3000W, with non-modular and full-modular configurations, and 80Plus Bronze, Gold and Platinum efficiency ratings. These products are tailored to various application scenarios, including gaming desktops, enterprise servers, industrial control equipment and office computers. For instance, the 80Plus Gold GN-1300W full-modular power supply unit is engineered for high-performance gaming desktops and professional workstations. It boasts high conversion efficiency, stable voltage output and low ripple, delivering a reliable power supply for high-end components such as multi-core CPUs, flagship GPUs and high-speed SSDs. Its full-modular design allows for flexible cable management, reducing chassis clutter and improving heat dissipation. For enterprise server applications, the 80Plus Bronze BF-550W full-modular power supply unit offers high reliability, low noise and consistent performance, supporting 24/7 continuous operation and minimizing server downtime, which is crucial for businesses relying on stable IT infrastructure. Quality control is a cornerstone of Yijian’s manufacturing process for power supply units, implemented through a ubiquitous QC team that oversees every stage from raw material procurement to finished product delivery. Prior to production, the IQC department conducts rigorous inspections on all incoming raw materials and components, verifying their performance, appearance and material composition to ensure compliance with production standards. During production, 2-3 QC inspectors are assigned to each process, conducting real-time checks and random sampling to identify and rectify quality issues promptly. After production, each power supply unit must pass more than 30 rigorous tests, including voltage stability, load capacity, high/low temperature resistance, aging, electromagnetic compatibility and safety performance tests. Only products that meet all quality criteria are released from the factory, guaranteeing that every PSU delivered to customers is of the highest quality. Yijian’s commitment to customer satisfaction extends to a comprehensive after-sales service system for power supply units. The company provides 1% spare parts for each order, ensuring customers have access to replacement components for urgent repairs, minimizing equipment downtime. Upon receiving customer feedback, the sales team responds within 2 hours, and a cross-departmental team develops a detailed 8D report within 24 hours, analyzing root causes and proposing targeted solutions. Yijian maintains close communication with customers to confirm solutions and ensure timely resolution of all issues. Additionally, the company offers long-term technical support and maintenance services, regularly tracking PSU usage to help customers optimize performance and extend product lifespan.
