Extended Product Information

FAQs

Does this card support USB Type-C devices?

The card only features Type-A ports. However, you can connect USB-C devices by using a USB-C to USB-A cable.

Will this work in my older USB 2.0 system?

Yes, the card is backward compatible with USB 2.0 and USB 3.0 devices, though it will be limited by the speed of the older peripheral.

Is extra power always required?

While the card functions for many devices without it, the SATA power connector is necessary when using high-power external hard drives or large storage arrays.

Which operating systems are supported?

The card supports most Windows versions (Windows 7 to 10), various Linux distributions, and select older Mac OS X versions.

Can I install this in a small form factor PC?

Yes, the product includes a low-profile (half-height) bracket specifically for small or slim desktop cases.

Troubleshooting

The device is not detected by the operating system.

Ensure the card is seated fully into the PCIe slot and that the motherboard BIOS recognizes the PCIe device.

Connected peripherals are not receiving enough power.

Verify that the internal SATA power cable is correctly connected from your power supply to the card.

Slow transfer speeds observed.

Check that the connected device is USB 3.1 Gen 2 compliant and that you are not using a restricted USB hub or extension cable.

Pros and Cons

Pros

  • High data transfer speeds up to 10Gbps
  • Versatile design with both internal and external ports
  • Includes brackets for both standard and slim PC cases
  • SATA power support for high-demand hardware
  • Broad support for Windows, Linux, and legacy Mac operating systems

Cons

  • Requires an open PCIe expansion slot
  • Needs an internal SATA power cable from the power supply for maximum performance
  • Limited to Type-A ports; requires adapters for native USB-C devices

Setup, Compatibility & Care

  1. Installation: Power off your computer and open the case. Locate an available PCIe slot (PCIe 3.0 recommended). Remove the slot cover on the back of the case and insert the card firmly.
  2. Power: If you are using power-intensive devices, connect a SATA power cable from your power supply to the internal connector on the card.
  3. Brackets: If you are using a compact or small form-factor case, unscrew the pre-installed full-height bracket and replace it with the included low-profile bracket.
  4. Drivers: The card is natively supported by most modern operating systems, meaning you can plug and play without searching for specific driver software.
  5. Care: Keep the card free of dust by blowing out the inside of your computer case with compressed air periodically. Ensure that all cables connected to the internal port are secured with cable ties to prevent interference with other components.
