Features: brand new and high quality High-performance chip: adopt V805 USB30 high-performance main control chip,make the operation more stable, and the compatibility and product performance are greatly improved. Imported for DC power chip: Synchronous rectification uses power MOSFETs with extremely low on-state resistance to replace rectifier diodes, so it can reduce the loss of the rectifier and improve the for DC/for DC converter High efficiency to meet the requirements of low voltage and high current the need for rectification. One-piece inductor (molded inductor): low-loss alloy powder is not die-cast, low impedance, no lead terminal, small parasitic capacitance, solid structure, accurate product, durable rust prevention, small size, large current. PCI-E X1 gold finger: high gold plating, strong oxidation resistance, good conductivity, and abrasion resistance. Multi-system compatibility:for Windows XP, Vista, 7 (driver installation required), for Windows 8, 10 system comes with a driver. Specifications: Name: PCI-E 1X to USB 3.0 TYPE+USB 19PIN Material: PCB Color: black Size: approx. 12x6.5x6cm/4.72x2.56x2.36in Package Includes: 1PC x PCI-E Expansion Card note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
