B2B Power Supply Solutions: 80Plus Gold/Platinum PSUs for Servers & Gaming

Power supply for computer is the core energy supply component of all computer systems, responsible for converting alternating current (AC) from the power grid into stable direct current (DC) that can be used by computer hardware components such as CPUs, GPUs, motherboards, and hard drives, and its performance and reliability directly determine the stable operation and service life of the entire computer system. Shenzhen Yijian Technology Co., Ltd., a professional PC power supply manufacturer with over 20 years of industry experience, has been committed to the research and development, production and sales of computer power supplies, and has built a comprehensive product system covering non-modular and full-modular types, with power ratings ranging from 550W to 3000W, and 80Plus certifications from Bronze to Platinum, which can meet the power supply needs of various computer systems such as home desktops, gaming computers, enterprise servers, and industrial control computers. Yijian’s computer power supply products are designed in strict accordance with the ATX standard, the most widely used power supply form factor in the world, which ensures universal compatibility with nearly all computer cases and motherboards, including ATX, MATX, and ITX specifications. All products support global universal AC input (100-240V 50/60Hz), which means they can operate stably on any power grid around the world without manual voltage adjustment, making them suitable for international users and global enterprises with cross-border business. In terms of core technical performance, Yijian’s computer power supplies adopt advanced circuit architectures such as active Power Factor Correction (PFC), LLC half-bridge resonance, synchronous rectification, and DC-to-DC conversion, which significantly improve energy conversion efficiency and reduce energy loss. The active PFC circuit corrects the power factor of the input current to nearly 1.0, reducing harmonic pollution to the power grid and complying with international energy efficiency regulations such as the EU’s ErP Directive and the US’s ENERGY STAR program. The LLC half-bridge resonance and synchronous rectification technologies minimize energy loss during high-frequency switching, while the DC-to-DC conversion technology realizes independent voltage regulation for each output channel, ensuring stable voltage output and low ripple noise. Yijian’s 80Plus Platinum certified computer power supplies, such as the AI-3000W and PL-850W, achieve a conversion efficiency of up to 94% at 50% load and over 92% at full load, which is far higher than that of non-certified power supplies. This high efficiency not only reduces electricity costs for users but also reduces heat generation, extending the service life of the power supply and other computer components. For different application scenarios, Yijian has developed targeted computer power supply products with unique design features. For home and office desktops with low to medium power demand, Yijian provides cost-effective non-modular computer power supplies with stable performance and low noise, which can meet the daily office, web browsing, and video playback needs of users. For high-end gaming desktops and content creation workstations, the company has launched high-power, high-efficiency full-modular computer power supplies such as the 80Plus Gold GT-1000W, GTJ-850W, and GN-1300W, which feature a single +12V rail design to provide high-current power output, supporting flagship CPUs and GPUs such as Intel Core i9, AMD Ryzen 9, NVIDIA RTX 4090, and AMD RX 7900 XTX, and meeting the extreme power demand of 4K gaming, 3D rendering, video editing, and other high-load tasks. For enterprise servers and data centers, Yijian’s 80Plus Bronze BF-550W and 80Plus Platinum AI-3000W computer power supplies are specially designed with 24/7 continuous operation capability, multiple protection mechanisms, and high-density component layout, ensuring uninterrupted power supply for server equipment and the safety of enterprise data. Yijian attaches great importance to the quality and reliability of computer power supplies, and has established a strict full-process quality control system. The company’s factory has passed the ISO9001 quality management system certification and ISO14001 environmental management system certification, and all computer power supply products have obtained a number of international and domestic certifications such as UL, EAC, FCC, CE, CCC, RoHS, TUV, CB, KC, and CSA, ensuring compliance with the safety, environmental protection, and performance standards of different countries and regions. Yijian’s QC team deploys 2-3 inspectors after each production process, implementing layer-by-layer inspection from raw material incoming inspection to finished product delivery. All computer power supplies undergo more than 30 rigorous tests, including sample testing before mass production, in-process performance testing, high-temperature aging testing, ripple noise testing, and protection function testing, to ensure that each product leaving the factory meets the highest quality standards. In terms of production capacity, Yijian has a strong advantage: the company’s factory covers an area of 20,000 square meters, has 5 advanced automated production lines, more than 500 skilled workers, and a monthly production capacity of over 300,000 units of computer power supplies, which can quickly respond to the large-order demand of customers and ensure on-time delivery. The company also has a perfect supply chain management system, establishing long-term cooperative relationships with well-known raw material suppliers at home and abroad, ensuring the stable supply of high-quality components such as capacitors, transformers, and wires. Yijian’s computer power supply products are equipped with a comprehensive set of protection mechanisms to safeguard the safety of the power supply and connected computer components. These protection mechanisms include Overvoltage Protection (OVP), Overcurrent Protection (OCP), Short Circuit Protection (SCP), Over Temperature Protection (OTP), Under Voltage Protection (UVP), and Over Power Protection (OPP). In the event of a fault such as a short circuit in peripheral equipment, overvoltage of the power grid, or overheating of the power supply, the corresponding protection function will be activated immediately, cutting off the power output in a few milliseconds to prevent damage to the CPU, GPU, motherboard, and other core components, minimizing the risk of hardware failure and data loss. In terms of after-sales service, Yijian has built a complete global after-sales service system for computer power supplies. The company promises to provide 1% spare units for each order, ensuring that customers have replacement parts on hand to minimize equipment downtime in case of product failure. After receiving customer feedback or complaints, the sales team will respond within 2 hours, and all departments will jointly issue a detailed 8D report within 24 hours to analyze the root cause of the problem and provide targeted solutions. Yijian also has a professional after-sales technical team that can provide customers with technical consultation, remote troubleshooting, and on-site maintenance services in multiple languages, ensuring that customer problems are solved in a timely and effective manner. Yijian’s computer power supply products have been widely recognized by the global market, with products exported to more than 50 countries and regions including the United States, Europe, Russia, Brazil, Japan, South Korea, Canada, the Middle East, and Southeast Asia. Customers in various countries have highly praised Yijian’s computer power supplies for their stable performance, reliable quality, high efficiency, and thoughtful after-sales service.
