ciciglow USB 3.0 PCI Express Expansion Card,PCIE to USB3.0 19/20 Pin Interface Compatible X4 / X8 X16 Riser Card for Windows Vista (ph62 full height)

High Speed Data Transmission: Using PCI‑Express. Interface through VL805 master bridge four USB3.0 interface high speed data transmission interface Reduce the Loss of Rectifier: Synchronous rectifier uses a power MOSFET with very low on state resistance to replace the rectifier diode, so it can reduce the loss of the rectifier, improve the efficiency of the DC/DC converter, and meet the needs of low voltage and high current rectifier Function: Low loss alloy powder die casting, low impedance, no lead end, small parasitic capacitance, precise product, durable rust prevention, small volume, large current Equipped with Fuse: Each 19p 20p output port is equipped with a self recovery fuse, when external short circuit fault access to the USB device, the short circuit current of high temperature will make internal fuse melts instantly generate high block open state, thereby limiting short circuit current, when the fault disappear, temperature drop, the flux will automatically revert to the original low resistance conducting state High Performance: High gold plating, oxidation resistance, good conductivity, wear resistance
