Ableconn PUSB31P2A USB 31 Gen 2 10 Gbps 2Port TypeA PCI Express PCIe x4 Host Adapter Card

Specification * Connector: - 2 x USB 3.1 Type-A female - 1 x 15-pin SATA power connector (optional connection) * Chipset: ASMedia ASM1142 * Software: - No driver installation is required on Mac OS X 10.9 to 10.10, and 10.12 to 10.14 (NOTE: does NOT work on OS X 10.11), Win10/8.1/8, Server 2012, and Linux 2.6.31 and later. The OS native built-in drivers feature UASP. - The ASMedia driver for 32/64 bit Windows 7/Vista, and Server 2008/2003 is available from our website. (ASMedia driver doesn't support UASP) * Data transfer rate: - USB 3.1 Gen2 up to 10 Gbps * Power: - Support up to 2A/5V on each USB-A downstream port. - The 15-pin SATA power connection is optional. Each USB port can provide up to 2A/5V power. If full loaded, it requires at least 20W (2 ports * 2A/5V) power. The power supply from PCIe bus to a 4-lane/low profile card is 25W (max) per PCI Express specification. * Instead of taking 5V power directly from power supply, our design includes power switching regulator circuit that automatically converts 12V from PCIe bus and/or from 15-Pin SATA power to ensure sufficient 5V/2A bus power on each USB port. * Low Profile PCIe Form Factor board * Supports PCIe 1.0, 2.0, or PCIe 3.0 motherboard * Compliant with PCI Express Specification 3.0 * Compliant with USB 3.1 Spec. Rev. 1.0, Intel xHCI Spec. 1.0. * Compliant with USB Attached SCSI Protocol (UASP) Specification 1.0. * Support USB 3.1, 3.0, 2.0, and 1.1 devices. * Include both Low Profile and Regular Size PCIe brackets * Fully RoHS compliant Note:UASP featue is only available with Windows and OS X built-in drivers. Currently, the ASMedia driver does not have UASP feature.
