1 Set Professional 4 Port PCI-E To USB 3.0 HUB PCI Express Expansion Card Adapter

Feature:Chip Model: VIASupport PCI Express 2.0 Bus SpecificationCompliance with USB3.0 Interface SpecificationProject Type: 3.0 PCI-E to USB Extension CardFour USB 3.0A bus connectors are provided.Plug-and-play and hot-swap functions.Compliance with xHCI Revision 0.95 specificationDownward compatibility with USB 2.0/1.1 specificationThe data transmission rate of USB 3.0 interface can reach 5 Gbps, and that of USB 2.0 interface can reach 480 Mbps.USB 3.0 interface can supply 900 mA current to external devices.Functions:USB 2.0 transmission speed, high transmission rate can reach 5 Gbps. In order to make a single USB 3.0 interface can enjoy the bandwidth of PCI-Express and fully guarantee the transmission rate of USB 3.0, please use a single USB 3.0 interface to connect USB 3.0 devices.It can provide more power when needed and automatically reduce power consumption when not needed. USB 3.0 can provide more power to support devices that need more power drivers. Devices charged with USB can complete charging faster. USB 3.0 supports standby, hibernation and pause states.Downward compatible version 2.0, USB 3.0 uses 9 pins. Four pins and USB 2.0 have the same shape and definition, while the other five are specially prepared for USB 3.0. USB 2.0 devices can be used on the USB 3.0 interface.Supported Operating Systems: Windows 2000, XP, Vista, WIN7 Operating SystemsUSB 3.0 high-speed adapter card can extend the USB 3.0 high-speed interface for computers through PCI-E interface of desktop motherboard or Express Card interface of notebook computer. The advantage of this is that the old computer does not need any hardware upgrade. It only needs a USB 3.0 high-speed adapter card to enjoy the ultra-fast transmission speed brought by the new USB 3.0 technology. (Some older motherboards don't have PCI-E interfaces, and some low-end laptops don't have Express Card interfaces.)With the new NEC main chip, four USB 3.0 interfaces can be extended simultaneously, and all USB 2.0 devices can be compatible downwards. For users who often conduct mass data transmission, the speed increase brought by USB 3.0 devices will undoubtedly save more time.Package Included:1 x PCI-E Express Card1 x Drive CD2x Screw
