Ableconn PUSB31P2A USB 3.1 Gen 2 (10 Gbps) 2-Port Type-A 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.
