Add two USB 3.0 ports via PCI Express

The Corn Electronics 2 Port USB 3.0 PCI Express Card adds two external USB 3.0 ports to a desktop system through a standard PCIe slot. It also provides a 19-pin internal header that can expand connectivity by two additional USB 3.0 ports. A 4-pin power connector and 20-pin interface support stable operation.

Suits builders adding front-panel

This card suits builders who need extra USB 3.0 ports for peripherals or front-panel headers on a desktop motherboard. It does not suit systems without an available PCI Express slot or users who require an internal 20-pin USB 3.0 header instead of the 19-pin connector provided.

PCI Express 2.0 Gen 1 interface

The adapter is designed to meet PCI Express 2.0 Gen 1 compliance and supports x1, x2, x4, x8 and x16 lane configurations. This single specification determines whether the card will function in the target motherboard slot.

商品問答

What connectors come on the card and what extra cable or header is needed to use the internal USB 3.0 19-pin connector?

The card provides two external USB 3.0 ports, a 20-pin Mini PCI Express interface and a USB 3.0 19-pin internal header; a compatible 19-pin to dual USB 3.0 bracket or cable must be purchased separately to expose the extra ports.

Which PCI Express slot widths are compatible with this x1 card?

The card works in x1, x2, x4, x8 or x16 slots because it uses a single-lane PCI Express 2.0 connection.

What real-world throughput can I expect from the 5 Gbps rating once the card is installed?

The 5 Gbps figure is the USB 3.0 bus ceiling; actual file-transfer speeds are lower due to protocol overhead, cable quality and the performance of the attached storage device.
