Yijian Technology, a preeminent manufacturer of PC power supply with two decades of specialized expertise, has solidified its position in the global market by prioritizing technological innovation, precision manufacturing, and uncompromising quality in every aspect of its PC power supply production. Headquartered in Shenzhen, the company’s 20,000-square-meter factory is a testament to its commitment to large-scale, high-quality production, housing 5 advanced automated production lines and a workforce of over 500 skilled professionals, enabling a monthly output of 300,000 PC power supply units. This production capacity, combined with a streamlined supply chain and intelligent production management, allows Yijian to fulfill both large-volume OEM orders and small-batch customized requests with timely delivery, catering to the diverse needs of global customers across the consumer, commercial, and industrial sectors. The R&D division of Yijian’s PC power supply business is a cornerstone of its success, comprising over 20 industry experts with more than 10 years of hands-on experience in power supply design and development. The team’s leadership includes veterans from internationally renowned power supply brands such as Great Wall, FSP, Delta, and Enhance, who bring a wealth of knowledge in circuit design, efficiency optimization, and safety engineering. This elite team is dedicated to pushing the boundaries of PC power supply technology, continuously developing new products that align with the latest industry standards and market demands. Yijian’s R&D efforts have yielded more than 100 patents and certifications for PC power supply products, covering innovations in topology design, power conversion efficiency, noise reduction, and safety protection mechanisms. All PC power supply products from Yijian hold a comprehensive suite of international certifications, including UL, EAC, FCC, CE, CCC, RoHS, TUV, and CB, ensuring compliance with the strictest safety and performance regulations in North America, Europe, Asia, and other key markets worldwide. The product portfolio of Yijian’s PC power supply is diverse and comprehensive, encompassing a full range of wattage ratings from 300W up to 3000W, with both non-modular and full-modular configurations available, and certified to 80Plus Bronze, Gold, and Platinum efficiency standards. This extensive product line is designed to address the unique power requirements of every PC application scenario, from basic home computing to high-end professional workstations. Non-modular PC power supply units from Yijian are engineered for simplicity and cost-effectiveness, featuring integrated cables that are easy to install, making them the perfect choice for entry-level home office PCs and basic commercial desktops where hardware configurations are relatively fixed. These units deliver stable power output for daily computing tasks such as web browsing, document processing, and video streaming, with a focus on reliability and low noise operation. Full-modular PC power supply units, on the other hand, offer unparalleled flexibility, with detachable cables that allow users to connect only the wires needed for their specific hardware setup. This modular design not only simplifies cable management, resulting in a cleaner and more organized PC case, but also improves airflow and cooling efficiency, which is critical for high-performance systems. Yijian’s full-modular PC power supply products, available in Gold and Platinum 80Plus certifications, are specifically designed for high-end gaming PCs, professional design workstations, and content creation systems. These units boast high power conversion efficiency (up to 90% for Platinum models), low ripple and noise, and fast transient response, ensuring that high-power components such as PCIe 5.0 graphics cards and multi-core CPUs receive a stable and consistent power supply even under extreme load conditions. This level of performance eliminates system instability, ensuring a seamless experience for gaming, 3D rendering, video editing, and other high-intensity tasks. In commercial and industrial settings, Yijian’s PC power supply products demonstrate exceptional durability and adaptability. For corporate office environments with large fleets of PCs, Yijian’s mid-wattage high-efficiency PC power supply units reduce energy consumption and operational costs, while their robust build quality and stable power delivery minimize the risk of system failures that could disrupt business operations and cause data loss. For light industrial applications, Yijian’s industrial-grade PC power supply units are built to withstand harsh operating conditions, including temperature variations, electromagnetic interference, and voltage fluctuations. These units feature enhanced circuit protection and ruggedized components, ensuring reliable operation in factory floors, workshops, and other industrial environments, and providing a stable power source for industrial PC equipment and automation systems. Quality control is ingrained in Yijian’s PC power supply production process, with a comprehensive quality management system certified to ISO9001 and an environmental management system certified to ISO14001. The company implements strict quality checks at every stage, starting with rigorous incoming material inspection (IQC) to ensure that all components, from capacitors and inductors to transformers and MOSFETs, meet the highest quality standards. The production process is monitored and managed by an intelligent system comprising E-SOP, Andon, and MES, which standardizes operations, enables real-time issue resolution, and tracks every product’s journey from raw material to finished good. Yijian’s ubiquitous QC team is present at every production step, with 2-3 QC professionals inspecting each process to ensure compliance with technical specifications. Before shipment, each PC power supply unit undergoes more than 30 rigorous tests, including load testing, aging testing, short-circuit protection testing, over-voltage protection testing, and high-low temperature testing, guaranteeing that only products that meet Yijian’s stringent quality criteria are delivered to customers. Yijian’s commitment to customer satisfaction extends far beyond the sale of its PC power supply products, with a comprehensive after-sales service system that provides global customers with prompt and reliable support.
