Modular Power Supply for Business PCs & Servers

Modular power supplies have redefined the standards of flexibility and performance in the PC power supply industry, and Shenzhen Yijian Technology Co., Ltd. has emerged as a pioneer in this domain by leveraging its extensive manufacturing experience, advanced R&D capabilities, and unwavering commitment to quality. Yijian’s modular power supply lineup is a testament to the company’s engineering prowess, featuring full-modular designs that cater to the diverse needs of gaming enthusiasts, enterprise IT professionals, and industrial users alike. At the core of Yijian’s modular power supply design is the pursuit of optimal system performance and user convenience. The full-modular cable architecture allows for complete customization of the power supply setup, enabling users to eliminate redundant cables and create a streamlined internal case layout. This not only enhances the aesthetic appeal of the system but also improves airflow, a critical factor in maintaining stable operating temperatures for high-performance components. In high-end gaming systems, where every degree of temperature reduction can translate to better performance and longer component life, Yijian’s modular power supplies make a tangible difference. For example, a gaming rig equipped with a Yijian GTJ-850W full-modular power supply can achieve a more efficient airflow path, reducing the overall system temperature by 3-5°C compared to a system with a non-modular power supply—this temperature drop can prevent thermal throttling of the CPU and GPU, ensuring consistent performance during extended gaming sessions. Yijian’s modular power supplies are also engineered to deliver exceptional electrical performance, with tight voltage regulation and low ripple noise. Voltage regulation is critical for ensuring that sensitive components like CPUs and GPUs receive a stable power supply, as even small voltage fluctuations can cause system instability, crashes, or permanent hardware damage. Yijian’s modular power supplies maintain voltage regulation within ±0.5% of the rated value, a level of precision that exceeds industry standards. This is achieved through the use of high-precision voltage regulators, feedback circuits, and premium components that minimize voltage drift even under varying load conditions. Ripple noise, which is the AC component present in the DC output of a power supply, is another key performance metric—high ripple noise can interfere with the operation of sensitive electronic components and cause data corruption. Yijian’s modular power supplies feature advanced filtering circuits that reduce ripple noise to extremely low levels (below 50mV for the +12V rail), ensuring a clean and stable power supply for all connected components. The performance of Yijian’s modular power supplies is further enhanced by their compliance with the latest industry standards, including ATX 3.0 and PCIe 5.0. The ATX 3.0 standard introduces new requirements for power supply reliability and transient power handling, mandating that power supplies can withstand 3x the rated power for short durations to accommodate the sudden power surges of modern GPUs. Yijian’s ATX 3.0-compliant modular power supplies, such as the GN-1300W and AI-3000W, are built to meet these stringent requirements, providing a robust power supply solution for the latest high-performance hardware. The PCIe 5.0 standard, meanwhile, introduces a new 16-pin power connector that can deliver up to 600W of power to a single GPU, eliminating the need for multiple 8-pin connectors and simplifying the power supply setup. Yijian’s modular power supplies equipped with the PCIe 5.0 connector offer a future-proof solution for gamers and content creators, supporting the next generation of GPUs without the need for adapter cables. In terms of manufacturing and quality control, Yijian sets the bar high for the modular power supply industry. The company’s 20,000-square-meter factory is equipped with 5 state-of-the-art production lines that utilize automated assembly and testing equipment, ensuring consistent product quality and high production efficiency. The factory operates under the guidance of ISO9001 and ISO14001 certifications, adhering to strict quality and environmental standards throughout the production process. Yijian’s quality control process is comprehensive, with IQC (Incoming Quality Control) inspections for all raw materials and components, in-process inspections after every production step, and FQC (Final Quality Control) inspections for all finished products. Every modular power supply undergoes over 30 rigorous tests, including efficiency testing, ripple and noise measurement, protection function validation, high-temperature aging, and vibration testing. Only products that pass all these tests are deemed ready for shipment, ensuring that customers receive nothing but the highest quality products. Yijian’s commitment to customer satisfaction extends beyond the production of high-quality modular power supplies to include comprehensive after-sales service. The company has established a global after-sales service network that provides fast and reliable support to customers in over 50 countries and regions. Yijian’s after-sales service team is composed of experienced technicians who can provide technical consultation, troubleshooting, and repair services for all modular power supply products. The company’s 2-hour response time guarantee ensures that customer inquiries are addressed promptly, and the 24-hour 8D report commitment ensures that any issues are resolved quickly and effectively. Additionally, Yijian provides 1% spare units for every order, allowing customers to minimize downtime in the event of a product failure. For OEM and ODM customers, Yijian offers customized after-sales service solutions, including dedicated technical support, on-site maintenance, and spare parts supply. Yijian’s modular power supply products have earned a reputation for excellence in the global market, with customers praising their performance, reliability, and flexibility. American customers have commended the company’s "professional design and high-quality products", while Russian customers have highlighted the "excellent after-sales support and long-term reliability". Brazilian customers, meanwhile, have noted the "seamless compatibility with local power grids and hardware configurations".
