Review on 🔌 I/O Crest 2 Port PCIe SuperSpeed USB 3.0 Card Adapter with UASP, SATA Power, Renesas Chipset by Randy Brimmer

The card fits easily into a PCI-E slot. But there are no card drivers in the OS, and the CD drivers that come with it don't work (at least for Windows 7). Drivers can be found on the manufacturer's website. The USB 3.0 slots can be accessed in two ways: directly on the card and/or by connecting a 19-pin cable (e.g. to the USB ports on the front of the case). The USB ports on the card itself work perfectly. The 19-pin connector is not very tight and the cable slips off easily.
