Frequently Asked Questions - PEXUSB3S24 StarTech.com
How do I install the PEXUSB3S24 card?
To install the PEXUSB3S24, turn off your computer and open the case. Insert the card into an available PCIe x4 slot, then connect the SATA power cable for supplemental power if needed. Replace the bracket screw, close the case, and boot your system. Install the drivers from the included disc or download the latest ones from StarTech.com.
Is the PEXUSB3S24 compatible with my motherboard?
The card works with any motherboard that has a PCIe x4 or larger slot (x8, x16). It is compatible with most desktop and tower systems, and low-profile brackets are included for slim cases. Ensure your system meets the PCIe 2.0 standard.
What is the maximum transfer speed of this USB 3.0 card?
The PEXUSB3S24 supports SuperSpeed USB 3.0 at 5 Gbps per port. Actual throughput may be lower due to system overhead and the device connected.
Can I connect a USB 3.0 hub to the internal header?
Yes, the internal 20-pin header can connect to a case-mounted front panel USB 3.0 hub or a separate internal hub. This provides two additional USB 3.0 ports accessible from the front of your PC.
Why is my computer not detecting the card?
First, verify the card is seated properly in the PCIe slot. Check that the SATA power cable is connected if the card requires it. Then install the appropriate drivers for your operating system. If using Windows, you may need to manually point to the driver folder.
Do I have to connect the SATA power cable?
The SATA power connector provides additional power to the card, ensuring stable power delivery to multiple devices. In most cases, it is recommended to connect it, especially when using high-power USB devices or loading multiple ports.
Can the PEXUSB3S24 be used in a Mac Pro?
Yes, the card works with macOS if your system has a PCIe slot. You may need to install the macOS driver from StarTech.com, as Apple does not include native support for all USB 3.0 controllers.
How many devices can I connect to the card?
The card has 4 USB 3.0 ports (2 external, 2 internal). You can connect up to 4 devices directly, or use hubs to connect more, up to the address limit of the USB controller.
Does the card support hot swapping?
Yes, all USB ports are hot-swappable. You can safely plug and unplug devices without turning off the computer, as long as the operating system supports hot swapping.
How do I update the drivers for the PEXUSB3S24?
Visit the StarTech.com support page for this model, download the latest driver for your operating system, and run the installer. You can also use Device Manager in Windows to update the driver manually.
