SFX Power Supply for Mini PCs: Compact, 80Plus Certified

SFX power supply is a miniaturized, high-power-density power supply product specially developed for small-form-factor (SFF) computing systems, and Shenzhen Yijian Technology Co.,Ltd, as a professional power supply manufacturer integrating R&D, design, production and sales, has created SFX power supply products with excellent comprehensive performance by virtue of its 20 years of professional focus on power supply R&D and manufacturing, and has become an important supplier of SFX power supply in the global market. Yijian’s SFX power supply is designed in strict accordance with the international SFX power supply specification, and the product size is strictly controlled within the standard SFX size range, which is fully compatible with all types of SFF chassis on the market, and can be easily installed and replaced without modifying the chassis structure. The power output of Yijian’s SFX power supply is designed with a single +12V high-current rail, which can provide up to 60A of continuous current output, fully meeting the high power demand of the CPU and graphics card in the SFF system, and the multi-channel +5V and +3.3V auxiliary power supply rails provide stable power for the motherboard, memory, hard disk and other peripheral components, ensuring the coordinated and stable operation of the entire SFF system. Yijian’s SFX power supply has a complete product line of efficiency grades, including 80Plus Bronze, Gold and Platinum, among which the Platinum-grade SFX power supply has a conversion efficiency of over 92% at 20% light load, over 94% at 50% typical load and over 90% at 100% full load, which is far higher than the national energy efficiency standard, and can effectively reduce the energy consumption and heat generation of SFF systems, and is an environmentally friendly and energy-saving power supply solution. The product is equipped with advanced active power factor correction (APFC) technology, which makes the power factor reach more than 0.99, effectively reducing the impact of the power supply on the power grid and complying with the international power quality standards such as IEC 61000-3-2. Yijian’s SFX power supply has a strong environmental adaptability, and the working temperature range is -20℃ to 70℃, which can stably work in various harsh environmental conditions such as high temperature, low temperature and high humidity, and is suitable for the use of SFF equipment in different regions and working environments around the world. The product adopts a sealed dust-proof design, which can effectively prevent dust from entering the internal circuit of the power supply, reduce the failure rate of the product and extend the service life. In terms of safety protection, Yijian’s SFX power supply is equipped with a comprehensive and perfect multi-layer protection system, which includes overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP), short circuit protection (SCP), overtemperature protection (OTP), overpower protection (OPP) and surge protection (SP), and all protection functions are independently controlled and quickly responded, which can provide all-round safety protection for the SFF system and avoid damage to the system components caused by various electrical faults and external power grid abnormalities. The cooling system of Yijian’s SFX power supply is specially optimized for the characteristics of SFF chassis: the product is equipped with a high-efficiency low-noise axial flow fan with a diameter of 80mm or 92mm, which adopts a hydraulic bearing or double ball bearing design with a service life of over 50,000 hours. The fan is equipped with an intelligent temperature control chip, which can automatically adjust the fan speed according to the real-time temperature of the power supply’s internal components, realizing the perfect balance between cooling performance and operating noise. When the SFF system is in light load operation, the fan runs at a low speed or even stops to achieve silent operation; when the system is in high load operation, the fan speed is increased to quickly dissipate heat and ensure the stable operation of the power supply. The application scenarios of Yijian’s SFX power supply cover all aspects of SFF computing: in the gaming field, it is the core power supply for high-performance ITX gaming hosts, supporting the power needs of mid-range CPUs and low-profile gaming graphics cards, and providing a compact and powerful gaming hardware platform for gaming enthusiasts who pursue small size and high performance; in the office field, it is used for mini office PCs and portable business workstations, reducing the occupied space of office equipment and improving the portability and flexibility of office work; in the industrial field, it is applied to embedded industrial control systems, small industrial monitoring equipment and intelligent sensor nodes, adapting to the narrow installation space of industrial sites and the strict requirements for power supply stability and reliability; in the home entertainment field, it is used for home mini entertainment desktops and 4K video playback hosts, providing a small and beautiful, low-noise power solution for home entertainment. Yijian’s SFX power supply is produced in a modern factory with a construction area of 20,000 square meters and 5 advanced automatic production lines, and the monthly production capacity is up to 300,000 units, which can fully meet the large-scale market demand and OEM/ODM customization needs of global customers. The production process of SFX power supply strictly abides by the ISO9001 quality management system and ISO14001 environmental management system, and all products must pass more than 30 rigorous performance tests and quality inspections before leaving the factory, including raw material inspection, component testing, semi-finished product testing, finished product aging testing and performance testing, to ensure that each SFX power supply product delivered to customers is of high quality and high reliability. Yijian’s R&D team, with rich experience and strong innovation capabilities, continuously tracks the development trend of the global SFF market and power supply technology, and constantly optimizes and upgrades the SFX power supply products, improving the product’s efficiency, power density and reliability, and launching new products to meet the changing market demand in a timely manner.
