Green PCIe x1 card with two 20-pin USB 3.0 headers and a low-profile metal bracket

SMUGDESK

SMUGDESK PCIe x1 to Dual 20-Pin USB 3.0 Internal Header Card with Low-Profile Bracket

SKU CH-8VM2-TZ7A9

Adds two 20-pin USB 3.0 internal headers via a PCIe x1 slot with a low-profile bracket included

  • Adds two internal USB 3.0 headers via a single PCIe x1 slot
  • Delivers USB 3.0 superspeed bandwidth for fast file transfers and device response
  • Includes a low-profile bracket for small-form-factor and full-size cases
  • Simple hardware installation into any standard desktop PCIe slot
  • Cost-effective internal header expansion for DIY builds and workstation upgrades

PCIe x1 USB 3.0 header expansion

This SMUGDESK card adds two internal 20-pin USB 3.0 headers through a single PCIe x1 slot. It targets builders whose motherboards lack enough front-panel connectors for modern cases. The adapter suits DIY assembly, workstation upgrades and multi-peripheral setups needing extra internal ports.

Sustained throughput stability

The controller maintains USB 3.0 superspeed bandwidth during extended file copies and continuous storage access. Performance stays consistent without the throttling seen in brief burst tests. Driver installation may be required on some operating systems to enable full operation.

Thermal and power profile

The low-profile bracket fits both full-size and small-form-factor cases without blocking airflow. Passive operation adds negligible heat or noise inside the chassis. Power draw remains minimal, sourced directly from the PCIe slot without extra connectors.

Questions about this item

How much power does the PCIe x1 card draw when both 20-pin USB 3.0 headers are active all day?

The card draws its operating power directly from the PCIe x1 slot and does not require an auxiliary power connector, so total draw stays within the slot's rated limit.

Which motherboard slot and case clearance must I already have to install this card?

You need one free PCIe x1 slot (or larger) on the motherboard and either a full-height or low-profile bracket opening, both of which are included with the card.

Will the dual 20-pin USB 3.0 headers work with my older front-panel USB 2.0 cables?

The headers are wired for USB 3.0 pinouts; plugging USB 2.0 front-panel cables into them will not provide a correct connection.
