PCIe 3.0 x4 USB 3.1 Adapter Card

This expansion card adds one USB 3.1 Type-A and one USB 3.1 Type-C port to a desktop PC via a PCIe 3.0 x4 slot. It uses ASM1142 and ASM1543 controllers to deliver up to 10 Gbps bandwidth. The bracket includes two external ports and the board provides two internal headers. A 15-pin SATA power connection is required for operation.

Builders Adding Front-Panel USB-C

The card suits system builders who need modern Type-C and Type-A ports on a case front panel or rear bracket. It fits PCIe x4, x8 or x16 slots and supports Windows 98SE through Vista. Buyers running Windows 7 or later should verify driver availability before purchase. Systems without a spare SATA power connector cannot supply the required 5 V 900 mA per port.

ASM1142 Controller With 10 Gbps Peak

The ASM1142 host controller bridges PCIe 3.0 to two USB 3.1 Gen 2 lanes for a combined 10 Gbps throughput. Each port supplies up to 900 mA at 5 V for bus-powered devices. The x4 link is backward compatible with x8 and x16 slots. Hot-plug and wake-on-USB keyboard or mouse functions are supported.

Questions about this item

Does the LRSU9A42-AC need a SATA power cable from my PSU to work?

Yes, the card requires a 15-pin SATA power connection to supply up to 900mA per USB port.

Will USB 2.0 devices still function when plugged into the Type-A or Type-C ports?

The ASM1142 controller is backward compatible with USB 2.0, so older peripherals operate at 480Mbps.

How can I verify the card is delivering 10Gbps bandwidth after installation?

Check Device Manager for an ASM1142 xHCI controller on a PCIe 3.0 x4 link and test with a USB 3.1 Gen2 drive.
