Ableconn PUSB31P2A USB 3.1 Gen 2 (10 Gbps) 2-Port Type-A PCI Express (PCIe) x4 Host Adapter Card

Ableconn PUSB31P2A USB 3.1 Gen 2 (10 Gbps) 2-Port Type-A PCI Express (PCIe) x4 Host Adapter Card

• Two USB Type-A connectors. Up to 10Gbps data transfer speed, twice as fast as USB 3.0.
• Low Profile board. Include both Low Profile and Regular Size PCIe brackets. PCIe x4 card fits in any PCIe 2.0 or PCIe 3.0 x4 or x8 or x16 slot.
• Instead of taking 5V power directly from power supply, our design includes power switching regulator circuit that automatically converts 12V from PCIe bus or from 15-Pin SATA power to ensure sufficient 5V/2A bus power on each USB port.
• No driver installation is required on MacOS 10.9 to 10.10, and 10.12 and later (NOTE: macOS 10.11 in-box driver doesn't support ASMedia USB 3.1), Win10/8, Server 2012 and later; Linux 2.6.31 and later. Driver download is available for 32/64 bit Windows 7/Vista, and Windows Server 2008/2003.
• Built with ASMedia ASM1142. Fully RoHS compliant. Made in Taiwan.

<p> <b>Specification</b> <br>* Connector: <br> - 2 x USB 3.1 Type-A female <br> - 1 x 15-pin SATA power connector (optional connection) <br>* Chipset: ASMedia ASM1142 <br>* Software: <br> - No driver installation is required on <b>Mac OS X 10.9 to 10.10, and 10.12 to 10.14 (NOTE: does NOT work on OS X 10.11)</b>, Win10/8.1/8, Server 2012, and Linux 2.6.31 and later. The OS native built-in drivers feature UASP. <br> - 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) <br>* Data transfer rate: <br> - USB 3.1 Gen2 up to 10 Gbps <br>* Power: <br> - Support up to <b>2A/5V</b> on each USB-A downstream port. <br> - 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. <br>* <b>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.</b> <br> <br>* Low Profile PCIe Form Factor board <br>* Supports PCIe 1.0, 2.0, or PCIe 3.0 motherboard <br>* Compliant with PCI Express Specification 3.0 <br>* Compliant with USB 3.1 Spec. Rev. 1.0, Intel xHCI Spec. 1.0. <br>* Compliant with USB Attached SCSI Protocol (UASP) Specification 1.0. <br>* Support USB 3.1, 3.0, 2.0, and 1.1 devices. <br>* Include both Low Profile and Regular Size PCIe brackets <br>* Fully RoHS compliant <br><b>Note:</b>UASP featue is only available with Windows and OS X built-in drivers. Currently, the ASMedia driver does not have UASP feature. </p>
