Two USB 3.1 Gen 2 Type-C ports

The MAIWO KC014 adds two USB 3.1 Gen 2 Type-C ports to a desktop computer through a PCI Express x4 slot. Each port supports data transfer up to 10 Gbps, giving a combined throughput of 16 Gbps. The card works with Windows 7, 8, 10, Mac OS and Linux, and is backward compatible with USB 3.0 and USB 2.0 devices. It draws all required power from the slot, so no extra power cable is needed.

Installation and common issues

The card fits any free PCIe x4, x8 or x16 slot and uses a self-powered IC, so you simply insert it and start the operating system. Drivers load automatically on the supported systems, making the process plug-and-play. The most frequent problem is attempting to install the card in a mini PCI Express slot, which is physically different and will not accept this full-size bracket. Verify that your motherboard has a standard PCIe x4 or larger slot before ordering.

Who this suits and who should look elsewhere

This card suits desktop owners who need two high-speed Type-C ports for external SSDs, hard drives or other USB 3.1 Gen 2 peripherals and have a spare PCIe x4 or wider slot. It is not for laptops or small-form-factor systems that lack a full-size PCIe slot, nor for users who require more than two Type-C ports or need the card to deliver fast-charging power beyond the 5 V/3 A per port rating.

Questions about this item

How do I verify the card is delivering the full 10 Gbps per port after installation?

Connect a USB 3.1 Gen 2 SSD enclosure and run a large sequential read test; sustained throughput near 10 Gbps confirms each port is operating at its rated speed.

What comes in the box and what must I source separately?

The card itself is included; you only need an available PCIe x4, x8 or x16 slot on the motherboard, no extra power cable is required.

Which slot width should I use — x4, x8 or x16 — for the best 16 Gbps aggregate bandwidth?

Any of those slots will work; the card uses a PCIe Gen3 x2 electrical link, so x4, x8 and x16 all provide the same 16 Gbps total throughput.
