- 4 Independent USB 3.0 ports for up to 5Gbps per port
- UASP support for more efficient data transfer
- Horizontal (stacked) USB port design
The PEXUSB3S400 PCI Express USB 3.0 Card adds 4 independent external USB 3.0 ports to any PCI Express x4-enabled computer system, with full bandwidth support (up to 5Gbps) per port when connected to USB 3.0 devices.Unlike other USB 3.0 cards, which share the maximum bandwidth between multiple ports, the card offers maximum transfer rates to each device when multiple devices are connected.
Further enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a External Drive Enclosures (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. See our UASP test results below for further details.
This 4-port USB 3.0 card features a stacked port layout, which places the ports one on top of the other, so more ports are able to fit into a smaller space. Plus, with a built-in SATA power connector, each USB port can provide up to 900mA of power to devices that draw power from a host bus connection (500mA for USB 2.0) by connecting to your computer power supply.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
Improved Performance with UASP
UASP is supported in Windows® 8, Server 2012 and Linux kernel 2.6.3 or later. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance.
At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources.
Test results were obtained using an Intel® Ivy Bridge system, StarTech.com add-on USB 3.0 cards, a UASP-enabled StarTech.com enclosure, and a SATA III solid state drive.
Applications
- Expand a system's USB capabilities with four additional external USB ports, for connecting additional external hard drives, CD/DVD drives, MP3 players, printers, scanners, webcams, game controllers, digital cameras, etc.
The StarTech.com Advantage
- Time-saving file transfers, up to 70% faster than traditional USB 3.0 when used with a UASP-supported enclosure

Troubleshooting
When you troubleshoot issues with a USB controller card, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
-
USB cables
-
USB devices
-
USB controller card
To test your setup components, try the following:
-
Use the USB cable, device, and controller card in another setup to see if the problem is with the components or the setup.
-
Use a different USB cable, device, and controller card in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
-
Test each cable individually.
-
Use short cables when you are testing.
When you test the USB device and controller card, it is recommended that you do the following:
-
Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Universal Serial Bus controllers.
-
If you do not see the USB controller card listed in Device Manager please see this FAQ: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows.
-
If the device is listed with an error, follow the instructions on the website to reinstall the drivers.
How To
To confirm that Windows detects your expansion card, complete the following:
- Press the Windows key+R, type devmgmt.msc, and press Enter.
- In Device Manager, under the appropriate heading, confirm that your expansion card is listed and that there isn't an exclamation mark next to it. For example, a USB controller card would be under Universal Serial Bus controllers.
Your expansion card is listed according to the name of the chipset. To determine the name of the chipset of your expansion card, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.
Before You Buy
The USB expansion cards derive power from the PCI or PCI Express slot on the motherboard. When high-powered USB devices are connected to the USB expansion card, the power provided by the slot may not be enough to power all of the devices and you should connect additional sources of power. When you troubleshoot issues, you should connect an additional source of power.
Symptoms that you are experiencing power-related issues include certain devices not working correctly, not all of the devices working at the same time, and certain devices not working at all.
Examples of low-powered USB devices include USB mice, keyboards, and flash drives. An example of a high-powered USB device is an external hard drive that does not have an external source of power.
