Two-port 10 Gbps USB 3.1 adapter

This PCIe x4 card adds two USB 3.1 Type-A ports using the ASM3142 controller. It delivers up to 10 Gbps bandwidth per port and maintains backward compatibility with USB 2.0 devices. A 15-pin SATA power connector supplies the required 12 V and 5 V rails. The low-profile and full-height brackets are both included.

For PCs needing extra high-speed ports

Builders adding fast external storage or peripherals to a desktop or server with a free x4, x8 or x16 slot will benefit. Systems without a spare PCIe slot or an available SATA power lead cannot use this card. Buyers who need USB Type-C connectors or internal header ports should look at a different model.

PCIe x4 host interface with ASM3142 controller

The card occupies a single PCIe 3.0 x4 lane and is compatible with wider x8 and x16 slots. The ASM3142 host controller manages two Type-A ports at 10 Gbps each. This interface and controller combination determines whether the card fits and performs in the target system.

Questions about this item

What free PCIe slot width does this card need to run at full 10 Gbps speed?

The card uses a PCIe 3.0 x4 interface and will also fit in x8 or x16 slots while keeping the same bandwidth.

Will my existing USB 2.0 flash drives and peripherals work on the two Type-A ports?

Yes, the ASM3142 controller is backward compatible with USB 2.0 so older devices run at 480 Mbps.

How can I verify each port is delivering the rated 900 mA after installation?

Plug in a bus-powered device and check the current draw in Device Manager or a USB power meter; each port supplies up to 5 V at 900 mA.
