500W Power Supply 80Plus Bronze for Entry-Level PCs & OEM

As a mainstream power rating in the PC power supply market, the 500W power supply is designed to cater to the power needs of most daily computing and light professional applications, with its adaptability and reliability making it a preferred choice for global PC manufacturers, system integrators and end users. Shenzhen Yijian Technology Co., Ltd., with its 20 years of focused experience in PC power supply manufacturing, has built a complete R&D, production and sales system for the 500W power supply, integrating advanced manufacturing technology and strict quality management to ensure that each product meets the highest industry standards. Yijian’s 500W power supply adopts a high-efficiency circuit design, supporting a wide AC input voltage range (180V-260V), which makes it suitable for use in different regions and countries with unstable power grids, effectively avoiding system shutdown or component damage caused by voltage fluctuations. This feature is particularly important for customers in emerging markets and regions with imperfect power infrastructure, ensuring the stable operation of computing equipment in complex power environments. In the field of industrial control, Yijian’s 500W power supply is applied in small industrial computers and embedded systems, providing stable power for industrial control equipment used in automated production lines, intelligent monitoring and data acquisition, with its anti-interference and shock resistance performance meeting industrial-grade application requirements. The product is equipped with a multi-level protection system, including over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), over-power protection (OPP), short-circuit protection (SCP) and over-temperature protection (OTP), which can quickly cut off the power supply in case of an abnormal situation, effectively protecting the core components of the computer and avoiding secondary damage. Yijian’s strict quality control process for the 500W power supply starts from the incoming inspection of raw materials: the IQC team conducts rigorous testing on all components such as capacitors, resistors and transformers to ensure that only qualified materials enter the production process. During production, 2-3 QC personnel are assigned after each process to inspect the product’s appearance, welding quality and circuit connection, eliminating defective products at the source. After the production is completed, each 500W power supply unit undergoes a full-load aging test and a variety of performance tests to ensure that all technical indicators meet the design requirements. The company’s intelligent MES system records the entire production process of each 500W power supply, from component assembly to finished product testing, enabling real-time traceability of product quality and quick location of problems in case of quality issues. Yijian’s 500W power supply products are exported to more than 20 countries and regions including the United States, Europe, Japan, South Korea, Russia and Brazil, and have won high recognition from global customers for their stable performance, reliable quality and excellent after-sales service. Customers from the United States have praised Yijian’s professional manufacturing strength and high-quality products, while Russian customers have recognized the company’s comprehensive after-sales support and timely problem-solving capabilities. Whether for pre-sales technical consultation, in-sales production coordination or after-sales maintenance support, Yijian’s professional team provides whole-process services to ensure the best user experience for customers.
