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

An 850W power supply is a high-performance mid-to-high power solution tailored for modern computing systems that demand stable, efficient, and robust power delivery, making it ideal for high-end gaming desktops, professional design workstations, small enterprise servers, and industrial control computers. Shenzhen Yijian Technology Co., Ltd., a professional PC power supply manufacturer with over 20 years of experience integrating R&D, design, production, and sales, has engineered 850W power supply products that embody cutting-edge technology, strict quality control, and customer-centric design, adhering to the company’s development concept of "Adhere to quality, advocate innovation, and win-win cooperation." Yijian’s 850W power supply complies with the latest ATX 3.0 standard and ATX 12V specification, optimized to meet the high transient power demands of modern high-performance GPUs and multi-core CPUs. The product features a single high-current +12V rail design, eliminating the limitations of split rails and delivering a continuous, stable current output to support intensive tasks such as 4K gaming, 3D modeling, video rendering, and data processing. Equipped with an advanced active Power Factor Correction (PFC) circuit, the power supply achieves a power factor exceeding 0.95, minimizing harmonic pollution to the mains grid while maximizing energy conversion efficiency. It holds 80Plus Gold or Platinum certification, ensuring a conversion efficiency of over 90% (Gold) or 92% (Platinum) under typical load conditions, reducing energy waste and heat generation for long-term cost savings and environmental sustainability. Yijian’s R&D team, consisting of over 20 professionals with more than 10 years of industry experience—many from renowned power supply enterprises like Great Wall, FSP, Delta, and Enhance—has meticulously optimized the 850W power supply’s circuit topology, thermal management, and voltage regulation. The team’s expertise in resonant conversion technology and soft switching design reduces power loss and electromagnetic interference (EMI), while ultra-low voltage ripple (below 50mV) protects sensitive components such as high-speed NVMe SSDs, DDR5 memory, and professional graphics cards, enhancing system stability and lifespan. For thermal management, the power supply integrates a 12cm or 14cm hydraulic bearing fan paired with an intelligent speed control system, adjusting fan speed dynamically based on operating temperature to balance silent operation (at low-to-medium loads) and efficient heat dissipation (at high loads). The internal heat sink adopts a large-area, high-density design to maximize heat transfer, ensuring the power supply operates within a safe temperature range even during 24/7 continuous use—critical for enterprise servers and professional workstations. Yijian’s 850W power supply is built with premium components, including Japanese long-life electrolytic capacitors, high-temperature resistant transformers, and precision inductors, selected to ensure reliability and durability. It features a comprehensive suite of protection functions: over-voltage (OVP), over-current (OCP), over-temperature (OTP), short-circuit (SCP), under-voltage (UVP), and over-power (OPP) protection, forming a multi-layered safety net that instantly cuts power in abnormal conditions to prevent hardware damage and data loss. The product’s versatile interface configuration includes a 20+4pin ATX motherboard connector, an 8pin (4+4pin combinable) EPS CPU connector, multiple SATA 3.0 ports for storage devices, dedicated M.2 power connectors, and 2-3 PCI-E 6+2pin connectors supporting PCI-E 5.0 graphics cards, ensuring compatibility with mainstream high-end hardware and facilitating future upgrades. Manufactured in Yijian’s 20,000-square-meter factory—certified to ISO9001 and ISO14001 standards—the 850W power supply undergoes a rigorous quality control process overseen by a ubiquitous QC team. Raw materials are inspected via IQC (Incoming Quality Control) to meet strict standards; 2-3 QC inspectors monitor each production process to eliminate defects; and every finished unit passes over 30 tests (voltage stability, load capacity, high/low temperature resistance, aging, EMI, etc.) before leaving the factory. The factory’s 5 production lines, staffed by over 500 workers, achieve a monthly capacity of 300,000 units, supported by intelligent systems (E-SOP, Andon, MES) for standardized operation, real-time problem-solving, and full production traceability. All 850W power supplies from Yijian have obtained international certifications including UL, TUV, 3C, CB, FCC, CE, KC, CSA, and C-TICK, complying with technical, safety, and environmental standards across global markets. Products are exported to the United States, Europe, Japan, South Korea, Canada, Russia, Brazil, and beyond, adapting to 110V/220V power grids. The company’s commitment to after-sales service includes 1% spare parts for each order, 2-hour response to customer feedback, and a detailed 8D report within 24 hours, ensuring timely, effective solutions. Whether for a gaming enthusiast building a high-performance rig, a designer relying on a workstation for 3D rendering, or an enterprise deploying small servers, Yijian’s 850W power supply delivers the reliability, efficiency, and performance required to power critical operations.
