PCIe x1 to Dual USB 3.0 Ports

This SMUGDESK adapter converts a single PCIe x1 slot into two independent USB 3.0 ports. It delivers a maximum transfer rate of 5Gbps for high-speed external drives and peripherals. A dedicated control chip maintains stable concurrent data transmission across both ports. The card fits standard full-height brackets and works in x1, x4, x8 or x16 slots.

Suits desktops needing extra USB 3.0 ports

Builders adding front-panel ports or connecting multiple external drives will find this card useful. It supports Windows and Linux with straightforward driver installation. Backward compatibility with USB 2.0 and 1.1 covers older keyboards, mice and flash drives. Buyers requiring more than two ports or internal headers should consider other options.

Two USB 3.0 ports at 5Gbps

The deciding specification is the pair of USB 3.0 ports running at up to 5Gbps each. This determines whether the adapter matches the bandwidth needs of your external SSDs or hard drives. Verify your motherboard has a free PCIe x1 or larger slot and a standard full-height bracket opening.

Questions about this item

How do I verify the card is delivering 5Gbps transfer speed after installation?

Connect a USB 3.0 storage device and check the link speed in Device Manager or lsusb -t; it should show 5Gbps for each active port.

What comes in the box and what must I supply?

The card with its full-height bracket is included; you only need an available PCIe x1, x4, x8 or x16 slot and the OS driver.

Which version of this adapter should I choose for a standard desktop case?

The single model listed uses a standard full-height bracket that fits common chassis and works in any PCIe x1, x4, x8 or x16 slot.
