Startech 2 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter with UASP, SATA Power, Dual Port USB 3 PCIe Controller (PEXUSB3S24), USB adapter, PCI Express x1, USB 3.0 x 2

DescriptionThe PEXUSB3S24 2-Port PCI Express USB 3.0 Card lets you add two USB 3.0 ports to your PCI Express-enabled computer system, with an optional SATA power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0).Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a External Drive Enclosures. Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers.The PCIe USB 3.0 adapter is compliant with USB 3.0 standards for data transfer speeds up to 5 Gbps, while still offering backward compatibility with existing USB 2.0 / 1.1 devices. For added versatility, the controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.Provides two external USB 3.0 ports with UASP supportSupports data rates up to 5 GbpsCompliant with PCI Express 2.0 specificationsSupports USB Battery Charging Specification 1.2Fully compliant with USB 3.0 rev 1.0 and Intel xHCI rev 1.0 specificationsBackward compatible with USB 2.0 and USB 1.0/1.1 devicesIncludes a low-profile/half-height installation bracketWhat’s in the BoxStarTech.com 2 Port PCI Express (PCIe) USB 3.0 Card with UASP – SATA PowerLow-profile bracketMain SpecificationsProduct DescriptionStartech 2 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter with UASP – SATA Power – Dual Port USB 3 PCIe Controller (PEXUSB3S24) – USB adapter – PCI Express x1 – USB 3.0 x 2Device TypeUSB adapterForm FactorPlug-in cardInterface (Bus) TypePCI Express x1PortsUSB 3.0 x 2Dimensions (WxDxH)2.2 cm x 6 cm x 6.5 cmWeight56 gData Link ProtocolUSB 3.0Data Transfer Rate5 GbpsCompliant StandardsUSB 3.0System RequirementsMicrosoft Windows Server 2008 R2, Microsoft Windows Vista (32/64 bits), Microsoft Windows 7 (32/64 bits), Microsoft Windows XP (32/64 bits), Microsoft Windows Server 2003 (32/64-bits), Windows 8 (32/64 bits)Designed ForP/N: CFASTRWU3, ST3300GU3B, ST4300U3C1, ST4300U3C1B, ST7300U3M, ST7300USB3B, ST7300USBME, USB3S2ESATA3Extended SpecificationsGeneralDevice TypeUSB adapterForm FactorPlug-in cardInterface (Bus) TypePCI Express x1NetworkingPortsUSB 3.0 x 2Connectivity TechnologyWiredData Link ProtocolSuperSpeed USB 3.0Data Transfer Rate5 GbpsCompliant StandardsUSB 3.0Expansion / ConnectivityInterfaces2 x USB 3.0 – 9 pin USB Type A (external)MiscellaneousIncluded AccessoriesLow-profile bracketCompliant StandardsFCC, RoHSSoftware / System RequirementsSoftware IncludedDrivers & UtilitiesOS RequiredMicrosoft Windows Server 2008 R2, Microsoft Windows Vista (32/64 bits), Microsoft Windows 7 (32/64 bits), Microsoft Windows XP (32/64 bits), Microsoft Windows Server 2003 (32/64-bits), Windows 8 (32/64 bits)Dimensions & WeightWidth2.2 cmDepth6 cmHeight6.5 cmWeight56 gEnvironmental ParametersMin Operating Temperature5 °CMax Operating Temperature50 °CHumidity Range Operating20 – 80%Compatibility InformationDesigned ForP/N: CFASTRWU3, ST3300GU3B, ST4300U3C1, ST4300U3C1B, ST7300U3M, ST7300USB3B, ST7300USBME, USB3S2ESATA3
