Features: Brand new and high quality High-Performance Chip: Utilizes the V805 USB30 high-performance main control chip for more stable operation, significantly improving compatibility and product performance. Imported DC Power Board: Synchronous rectification uses power MOSFETs with extremely low on-state resistance to replace rectifier diodes, reducing rectifier loss and enhancing DC/DC converter efficiency to meet low voltage and high current rectification demands. Integrated Inductor (Molded Inductor): Low-loss alloy powder is not pressure-cast, resulting in low impedance, no lead terminals, small parasitic capacitance, solid structure, precise product, durable anti-rust properties, small size, and high current capacity. PCI-E X1 Gold Finger: High gold plating provides strong oxidation resistance, good conductivity, and wear resistance. Multi-System Compatibility: Supports Windows XP, Vista, 7 (driver installation required). Windows 8 and 10 systems come with a built-in driver. Specification: Name: PCI-E 1X to USB 3.0 TYPE+USB 19PIN Material: PCB Color: Black Size: Approx. 12x6.5x6cm/4.72x2.56x2.36in Note: Please allow 0-1cm error due to manual measurement.
