750W Power Supply 80Plus Gold/Platinum for B2B PC Builds

A 750W power supply is a high-performance mid-to-high power power supply solution, specially designed for mid-to-high-end computing systems equipped with high-performance CPUs, mid-range to high-end GPUs and multiple storage devices, and is widely applicable to high-end home gaming desktops, professional design workstations, small and medium-sized enterprise servers and industrial control computers that require stable and high-power power supply. Shenzhen Yijian Technology Co., Ltd., a professional power supply manufacturer with over 20 years of experience in R&D and production of PC power supplies, has developed and manufactured 750W power supply products that comply with the latest ATX 3.0 standard, integrating advanced circuit design, high-quality component selection and strict quality control, with excellent performance, high energy efficiency and strong reliability, making it an ideal power supply choice for mid-to-high-end computing scenarios. Yijian’s 750W power supply adopts an advanced active power factor correction (PFC) circuit design with a power factor of more than 0.95, which not only improves the energy conversion efficiency of the product but also reduces the harmonic pollution to the mains grid, in line with global environmental protection and energy-saving development trends, and the product has obtained 80Plus Gold or Platinum efficiency certifications, ensuring that the power supply maintains high conversion efficiency in the load range of 20% to 100%, reducing energy waste and saving electricity costs for users. The 750W power supply is optimized with a single high-current +12V rail design, which delivers a stable and high current output to meet the main power consumption needs of modern high-performance CPUs and GPUs, avoiding the power supply bottleneck caused by multiple +12V rail division, and ensuring the smooth operation of the computer system during high-load tasks such as 3D gaming, video editing, 3D modeling and data processing. The product is equipped with a complete set of standard and extended power supply interfaces, including 20+4pin ATX motherboard power, 8pin EPS CPU power (with 4+4pin combination), multiple SATA 3.0 power interfaces, M.2 power interfaces and PCI-E 6+2pin power interfaces (supporting PCI-E 5.0), which can be perfectly matched with mainstream mid-to-high-end hardware components on the market, and facilitate the connection of multiple storage devices and high-performance graphics cards, meeting the needs of hardware upgrade and expansion for users. Yijian’s R&D team, composed of over 20 professionals each with more than 10 years of power supply design experience and core members from renowned power supply enterprises such as Great Wall, FSP, Delta and Enhance, has in-depth expertise in the circuit topology design, thermal management and noise reduction of 750W power supplies. The team optimizes the voltage regulation circuit and transient response performance of the 750W power supply, controlling the voltage output ripple at an ultra-low level, which effectively protects sensitive hardware components such as high-speed solid-state drives and high-frequency memory modules from voltage fluctuations, and improving the stability and service life of the entire computer system. The R&D team also adopts an advanced thermal management solution for the 750W power supply, combining a large-area high-density heat sink with a 14cm high-efficiency silent hydraulic bearing fan, and matching it with an intelligent temperature control speed regulation system, which adjusts the fan speed according to the actual operating temperature of the power supply, achieving a perfect balance between heat dissipation efficiency and operating noise. At low and medium loads, the fan runs at a low speed with extremely low noise, providing a quiet working and entertainment environment; at high loads, the fan speed increases automatically to enhance heat dissipation, ensuring the power supply operates within a safe temperature range under long-term high-load conditions. Yijian’s 750W power supply is equipped with a comprehensive set of protection functions including over-voltage (OVP), over-current (OCP), over-temperature (OTP), short-circuit (SCP), under-voltage (UVP) and over-power (OPP) protection, which form a multi-layered safety protection network for the power supply and the connected computer hardware. In case of abnormal working conditions such as voltage surge, hardware short circuit, overheating and over-power load, the protection system will be activated instantly to cut off the power supply, preventing damage to the power supply itself and connected computer hardware, and maximizing the safety of the equipment and important data, which is especially important for professional workstations and enterprise servers that store and process key data. Yijian implements a stringent full-process quality control system for the production of 750W power supplies, supported by a ubiquitous QC team that conducts strict incoming quality control (IQC) on all raw materials such as Japanese solid capacitors, high-temperature resistant transformers, precision inductors and PCBs to ensure that the components meet the high production standards of the company; during the assembly process, 2-3 QC inspectors are assigned to each production process to verify the welding quality, component installation accuracy and wire connection reliability, eliminating defective semi-finished products at the source; every finished 750W power supply undergoes more than 30 rigorous tests including voltage stability, load capacity, high and low temperature resistance, aging test, electromagnetic compatibility test and safety performance test, and only products that pass all tests are delivered to the market. The production of Yijian’s 750W power supply is carried out in a 20,000-square-meter modern factory with 5 advanced production lines and over 500 skilled workers, and the factory has passed ISO9001 quality management system certification and ISO14001 environmental management system certification, with a monthly production capacity of 300,000 power supply units to ensure timely supply for global customers. The factory has introduced intelligent production management systems such as E-SOP, Andon and MES, which realize the digitalization, standardization and traceability of the production process of the 750W power supply. The E-SOP system provides workers with standardized digital operation guidelines, ensuring the consistency of the production process of each 750W power supply; the Andon system enables real-time monitoring of the production line, sending instant alerts when production abnormalities occur, and facilitating rapid collaboration between relevant departments to resolve problems, ensuring the smooth progress of production; the MES system records all production data and product information of the 750W power supply in real time, including component batch numbers, testing results and production time, which can track the entire production process of each product and provide accurate data support for after-sales maintenance and product quality improvement. All 750W power supply products from Yijian have obtained a full range of international authoritative certifications including UL, EAC, FCC, CE, CCC, RoHS, TUV, CB, KC and CSA, complying with the technical, safety and environmental standards of different countries and regions across North America, Europe, Asia and South America, and the products are exported to the United States, Europe, Japan, South Korea, Canada, Russia, Brazil, Mexico, the Middle East and Southeast Asia, adapting to the local power grid specifications (110V/220V) and usage requirements.
