SMUGDESK

SMUGDESK PCIe X1 to Dual 20Pin USB 3.0 Header Card Low Profile Bracket

SKU CH-8MTR-DWYM4

Adds two internal USB 3.0 headers via a PCIe x1 slot, reaching 5 Gbps with a low-profile bracket for slim cases

  • Adds two front-panel USB 3.0 headers for 5 Gbps SuperSpeed transfers
  • PCIe x1 card fits x4, x8 and x16 slots on ASUS, MSI, Gigabyte, ASRock, Dell, HP and Lenovo boards
  • Half-height bracket included for slim small-form-factor and 2U chassis builds
  • Bus-powered design needs no extra SATA power cable for simpler internal wiring
  • Plug-and-play on Windows 11, 10, 8.1, 7 and Linux with hot-swap support

Expand Internal USB 3.0 Headers

This PCIe X1 card adds two 20-pin USB 3.0 internal headers so desktop front-panel ports can run at SuperSpeed 5Gbps. It fits standard and low-profile slots on Intel and AMD motherboards from major vendors and branded pre-built systems. No extra power cable is needed because the card draws power from the PCIe bus. Installation is plug-and-play on Windows 11, 10, 8.1, 7 and Linux with hot-swap support.

Upgrade from Missing or USB 2.0 Headers

The card replaces a missing motherboard header or upgrades a USB 2.0 front-panel connection to USB 3.0 speeds. The jump is worth it when you need 10x faster file transfers for USB flash drives, external hard drives or front-panel peripherals such as card readers and fans. It also solves the issue on older PCs and industrial control hosts that lack native USB 3.0 internal connectors.

Limited by PCIe X1 Bandwidth and Header Count

The single-lane PCIe X1 interface caps total throughput so two simultaneous 5Gbps devices cannot both sustain peak speed. Only two internal headers are provided, so builds requiring more than two front-panel USB 3.0 ports need additional expansion. The card does not add external ports, SATA connectors or any other interface beyond the dual 20-pin headers.

Questions about this item

Will the low-profile bracket let this card fit in a 2U compact chassis?

Yes, the included half-height bracket is designed for slim small-form-factor and 2U compact chassis installation.

Does the card need a SATA power cable, or does it draw power from the PCIe slot alone?

It is bus-powered from the PCIe slot, so no extra SATA power cable is required.

What is the maximum transfer speed of the two 20-pin USB 3.0 headers?

Each header supports up to 5Gbps SuperSpeed USB 3.0, which is 10x faster than USB 2.0.
