PCI-Express USB-C Card | 10Gbps | PCIe Gen3 x4 | 2-Year Warranty

This PCIe USB 3.1 Gen 2 card installs into an available PCI-Express slot in your computer and enables you to upgrade your current system by adding two USB-C (10Gbps) ports.

Faster USB Performance 

Also known as USB 3.2 Gen 2x1, this USB 3.1 Gen 2 card adds two 10Gbps USB Type-C ports to your computer.

Returns FAQs

What is your returns criteria?
14 days from date of receipt, or expected date of receipt on non-tracked items.

How do I go about returning my order?
Please contact us via our contact page with your order number. We will provide you with an RMA number and return instructions, including your return deadline and whether a freepost label applies to your order.

Do I need to contact you before returning my order?
Yes, to obtain an RMA number before sending anything back.

Does my item have to include its original packaging?
