The high-performance main control chip adopts VL805 USB3.0 high-performance main control chip, which makes the operation more stable, compatible, and product performance is greatly improved. Synchronous rectification uses an on-resistance power MOSFET to replace the rectifier diode, so it can reduce the loss of the rectifier Improve the efficiency of the DC/DC converter to meet the needs of low voltage and high current rectification. Low-loss alloy powder die-casting, low impedance, no lead terminal, small parasitic capacitance, solid and firm structure, accurate product, long-lasting rust prevention, small size, large current. Multi-system compatibility Compatible with Windows XP, Vista, 7 (driver installation required), Windows 8, 10 system comes with driver.<br><br>Product name: PCI-E to USB3TYPE+USB 19PIN Input interface: PCI-E x1 compatible x4/x8/X16 compatible with USB2.0, USB1.1 Colour: black Material: PCB Size: 12x6.5x6CM<br><br>Package Contents: 1 * Expansion Card<br><br>Only the above package content, other products are not included.
