Pci-e to 2 Port Usb3.0 Expansion Card Pci Express 5.0gbps Pci

Dual port expansion USb3 0 high-speed transmission port, compatible with simultaneous transmission, efficient and time-savingNew process, low heating, fast speed and stable operationWith the thickened gold deposition process, gold has the advantages of good conductivity and strong oxidation resistance. Surface gold deposition can ensure more stable transmissionThis expansion card has two standard USb3 0 interface, there are 9 contact points in total in 3.0 interface, while there are only 4 in 2.0 interface, indicating that 9 lines are required for data transmission in 3.0 interface If all 9 wires are in contact, it will work in 3.0 mode. If one wire is not in contact, it will work in 2.0 modeEach interface is equipped with an independent interface protection fuse. When the external USB device is short circuited and the current is too large, the power supply can be cut off instantly, so as to protect the peripherals and computer from damage. After troubleshooting, it will automatically return to normalColour:blackMaterial:PCBPackage Contents:1 * Adapter Card1 * BaffleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
