Review on StarTech.com 4-Port PCIe SuperSpeed USB 3.0 💻 Controller Card with UASP and SATA Power (PEXUSB3S4V) by John Hill

I have a StarTech USB3 capture card that is not working with my motherboard's onboard USB3 controller and the troubleshooting guide recommended this card. Now it works great! A little pricey compared to some other USB3 controllers, but as long as my capture card works I'm happy with it. Please note that you must be precise when screwing as the USB ports are perpendicular to the expansion slot. card into the slot. If you line it up and plug in the USB connectors on both ends before screwing the card on, you can make sure it's oriented the right way. Also note that in my case at least one additional SATA power connector had to be connected for the card to work.
