850W ATX3.1 Power Supply — 80Plus Gold/Platinum, Full-Modular

An 850W power supply is a high-performance, versatile component designed to meet the demands of mid-to-high-end computing systems, offering the perfect combination of power, efficiency, and reliability. It is widely used in scenarios such as high-end gaming desktops, professional video editing workstations, small enterprise servers, and industrial control equipment—where stable power delivery and long-term durability are essential. Shenzhen Yijian Technology Co., Ltd., a professional PC power supply manufacturer with over 20 years of experience, has developed its 850W power supply to uphold the company’s business purpose of "quality first, customer first, win by excellence," leveraging advanced R&D, premium materials, and strict quality control. Yijian’s 850W power supply is built with a focus on performance and efficiency, featuring an active PFC circuit that ensures a power factor of over 0.95, optimizing energy utilization and reducing the environmental impact. The power supply holds 80Plus Gold certification, achieving conversion efficiency of over 90% at typical load, 87% at 20% load, and 87% at 100% load. This high level of efficiency not only lowers electricity bills but also minimizes heat generation, extending the lifespan of the power supply and connected components. The resonant LLC converter topology further enhances efficiency by reducing switching losses, while the single +12V rail design delivers a continuous current output of up to 70.8A, ensuring ample power for high-performance CPUs and GPUs. The 850W power supply’s compatibility with modern hardware standards is a key advantage. It supports PCI-E 5.0, making it compatible with next-generation GPUs that require high power delivery, and includes a 20+4pin motherboard connector, an 8pin (4+4pin) CPU connector, multiple SATA 3.0 connectors, and dedicated M.2 power connectors. This comprehensive interface configuration ensures compatibility with all modern motherboards, processors, storage devices, and graphics cards, making it a versatile choice for system builders and upgraders. For content creators and professionals, the power supply’s ability to handle multi-tasking and resource-intensive applications—such as 3D rendering, video editing, and machine learning—is critical. The stable voltage output and low ripple (below 50mV) ensure that sensitive components like high-speed memory and SSDs operate smoothly, preventing data loss or corruption. Yijian’s R&D team, composed of over 20 professionals with more than 10 years of experience, has integrated advanced technologies to enhance the 850W power supply’s reliability. The use of Japanese long-life electrolytic capacitors ensures stable performance even under extreme conditions, while the precision-machined heat sink and 12cm PWM fan provide efficient thermal management. The fan’s hydraulic bearing reduces noise and vibration, extending its lifespan and ensuring quiet operation—even during long gaming sessions or rendering tasks. The power supply’s ability to withstand wide temperature ranges (-20℃ to 70℃) and voltage fluctuations makes it suitable for industrial control applications, where harsh environments are common. Yijian’s commitment to quality is reflected in its production process. The 850W power supply is manufactured in a 20,000-square-meter factory with 5 production lines and over 500 workers, operating under ISO9001 and ISO14001 certifications. The factory’s intelligent systems—E-SOP, Andon, and MES—standardize production, enable real-time tracking, and facilitate rapid problem resolution. Every power supply undergoes over 30 tests, including aging tests, high/low temperature cycling, short-circuit protection testing, and EMI testing, to ensure reliability and compliance with international standards. The ubiquitous QC team oversees every stage of production, from raw material inspection to final testing, ensuring that only flawless products reach customers. Safety is a top priority for Yijian, and the 850W power supply includes comprehensive protection functions: over-voltage, over-current, over-temperature, short-circuit, under-voltage, and over-power protection. These features safeguard the power supply and connected hardware from damage caused by electrical anomalies, providing users with peace of mind. All 850W power supplies are certified to UL, TUV, 3C, CB, FCC, CE, and other global standards, ensuring compatibility and safety in markets worldwide. Yijian’s after-sales service is second to none, with 1% spare parts for each order, 2-hour response to customer feedback, and a detailed 8D report within 24 hours. Products are exported to over 20 countries and regions, with local support to address customer needs. Whether for a gaming rig, a workstation, or a server, Yijian’s 850W power supply delivers the performance, efficiency, and reliability required to power the most demanding computing tasks.
