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

Shenzhen Yijian Technology Co., Ltd. stands as a paragon of specialization and expertise in the PC power supply industry, with over two decades of dedicated research, development, and manufacturing experience that has shaped it into a global leader in delivering high-quality, high-performance PC power supply solutions. Since its inception in 2006, the company has remained singularly focused on the PC power supply sector, eschewing diversification to hone its craft, build deep technical expertise, and develop a nuanced understanding of the unique challenges and requirements of powering modern PC systems—from entry-level home desktops to cutting-edge gaming rigs and professional workstations. This unwavering focus has allowed Yijian to create a product portfolio that is second to none in terms of performance, reliability, and adaptability, with PC power supply units that cater to every conceivable application scenario and customer need. Yijian’s manufacturing capabilities are a cornerstone of its success in the PC power supply market, with a 20,000-square-meter modern factory equipped with 5 advanced automated production lines and staffed by a team of over 500 skilled engineers, technicians, and production workers. This robust setup enables the company to achieve a monthly production capacity of 300,000 PC power supply units, making it capable of fulfilling large-volume OEM/ODM orders for computer manufacturers and distributors worldwide, as well as accommodating small-batch customized requests for niche applications. The production process is governed by a suite of intelligent manufacturing systems, including E-SOP, Andon, and MES, which work in tandem to standardize operations, streamline production workflows, enable real-time issue resolution, and provide end-to-end traceability of every PC power supply unit—from the sourcing of raw materials to the final shipment to the customer. This intelligent approach not only maximizes production efficiency but also ensures consistent quality across all batches, a critical factor in meeting the stringent standards of global customers. The technological prowess of Yijian’s PC power supply business is driven by its elite R&D team, a group of over 20 industry veterans each with a minimum of 10 years of hands-on experience in power supply design, development, and testing. The team’s core members are recruited from internationally renowned power supply brands such as Great Wall, FSP, Delta, and Enhance, bringing with them a wealth of knowledge in advanced circuit topology, efficiency optimization, safety engineering, and noise reduction techniques. This seasoned team is responsible for driving Yijian’s innovation agenda, continuously developing new PC power supply products that align with the latest industry standards—such as ATX 3.0 and PCIe 5.0—and market trends, while also refining existing products to enhance their performance, efficiency, and reliability. The R&D team’s efforts have yielded remarkable results, with Yijian holding more than 100 patents and international certifications for its PC power supply products, covering a wide spectrum of technical innovations in power conversion, structural design, safety protection, and energy efficiency. All of Yijian’s PC power supply units are certified to a comprehensive range of international standards, including UL, EAC, FCC, CE, CCC, RoHS, TUV, CB, KC, CSA, and C-TICK, ensuring that they comply with the strictest safety, performance, and environmental regulations in North America, Europe, Asia, Australia, and other key global markets. This extensive certification portfolio allows Yijian’s PC power supply products to be seamlessly sold and deployed in over 20 countries and regions, from the United States and Western Europe to Japan, South Korea, Russia, Brazil, and the Middle East. Yijian’s PC power supply product line is meticulously engineered to offer a diverse range of solutions, with wattage ratings spanning from 300W for entry-level systems to an impressive 3000W for high-performance workstations and industrial PC equipment. The product range includes both non-modular and full-modular configurations, each with distinct advantages tailored to specific use cases, and all are available with 80Plus Bronze, Gold, or Platinum efficiency certifications— a testament to Yijian’s commitment to energy efficiency and environmental sustainability. Non-modular PC power supply units feature integrated cables, offering a cost-effective, easy-to-install solution ideal for entry-level home office PCs and basic commercial desktops with fixed hardware configurations. These units deliver stable, reliable power for daily computing tasks such as web browsing, document editing, and video conferencing, with a low-noise design that ensures a quiet and comfortable working environment. Full-modular PC power supply units, by contrast, feature detachable cables that allow users to connect only the wires required for their specific hardware setup, offering unparalleled flexibility in cable management. This design not only results in a cleaner, more organized PC case but also improves airflow and cooling efficiency—essential for high-performance systems that generate significant heat. 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 exceptional electrical performance, including high power conversion efficiency (up to 90% for Platinum models), low ripple and noise, and rapid transient response, ensuring that high-power components such as PCIe 5.0 graphics cards, multi-core CPUs, and high-speed NVMe SSDs receive a stable and consistent power supply even under extreme load conditions. This level of performance eliminates system instability, ensuring a seamless user experience for intense gaming, 3D rendering, 4K video editing, and other high-demand tasks. In commercial and industrial environments, Yijian’s PC power supply products demonstrate exceptional durability and adaptability. For corporate offices 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 costly data loss. For light industrial applications, Yijian’s industrial-grade PC power supply units are built to withstand harsh operating conditions, including wide 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 embedded in every aspect of 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 rigorous quality control measures at every stage, starting with strict 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 by a ubiquitous QC team, with 2-3 QC professionals assigned to inspect each production step to ensure compliance with strict 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 extends far beyond the sale of its PC power supply products, with a comprehensive after-sales service system that provides global customers with prompt, reliable, and professional support.
