At the core of Yijian’s PC power supply business is its elite R&D team, composed of more than 20 industry professionals with a minimum of 10 years of hands-on experience in power supply design and development. The team’s leadership includes veterans from leading international power supply brands such as Great Wall, FSP, Delta, and Enhance, who bring a wealth of expertise in circuit topology, efficiency optimization, safety engineering, and product design. This experienced team is responsible for driving Yijian’s technological innovation, developing new products that align with the latest industry standards and market trends, and optimizing existing products to enhance performance and efficiency. The R&D team’s efforts have led to Yijian holding more than 100 patents and international certifications for its PC power supply products, covering a wide range of technical innovations in power conversion, noise reduction, safety protection, and structural design. All of Yijian’s PC power supply products are certified to international standards such as UL, EAC, FCC, CE, CCC, RoHS, TUV, CB, KC, CSA, and C-TICK, ensuring compliance with the stringent safety, performance, and environmental regulations of countries and regions worldwide. This global certification allows Yijian’s PC power supply products to be sold and used in over 20 countries and regions, including the United States, Europe, Japan, South Korea, Canada, Russia, Brazil, and the Middle East. Yijian’s PC power supply product line is diverse and comprehensive, offering a full range of wattage ratings from 300W to 3000W, with both non-modular and full-modular configurations available, and certified to 80Plus Bronze, Gold, and Platinum efficiency levels. Each product series is engineered to meet the specific power requirements of different application scenarios, ensuring optimal performance and reliability. Non-modular PC power supply units are designed for simplicity and cost-effectiveness, featuring integrated cables that are easy to install, making them an ideal choice for entry-level home office PCs and basic commercial desktops with fixed hardware configurations. These units deliver stable power output for daily computing tasks, with a low-noise design that ensures a quiet working environment. Full-modular PC power supply units, on the other hand, offer maximum flexibility with detachable cables, allowing users to connect only the wires needed for their specific hardware setup. This design simplifies cable management, improves airflow within the PC case, and enhances cooling efficiency—critical factors 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 and ensures a seamless user experience for gaming, 3D rendering, video editing, and other high-intensity tasks. In commercial office environments with large PC fleets, Yijian’s mid-wattage high-efficiency PC power supply units play a vital role in reducing energy consumption and operational costs. Their high power conversion efficiency minimizes energy waste, while their robust build quality and stable power delivery prevent unexpected system failures that could lead to data loss and workflow disruptions. 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 settings, and providing a stable power source for industrial PC equipment and automation systems. Quality is the cornerstone of Yijian’s PC power supply production, with a comprehensive quality management system certified to ISO9001 and an environmental management system certified to ISO14001. The company implements strict quality control measures at every stage of the production process, starting with rigorous incoming material inspection (IQC) to ensure that all components meet the highest quality standards. The production process is monitored by a ubiquitous QC team, with 2-3 QC professionals assigned to inspect 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 flawless products reach customers. Yijian’s commitment to customer satisfaction is further demonstrated by its comprehensive after-sales service system for PC power supply products. For every order, the company provides 1% free spare parts to facilitate quick replacement and minimal downtime in the event of a fault.
