Enabling External USB 3.0 Socket in Motherboard with only USB 2.0 Header

I love my CoolerMaster HAF case. It has two external USB ports on its front: a USB 2.0 and a USB 3.0. My motherboard is a Gigabyte F2A68HM-H. The F2A68HM-H has two USB 2.0 headers and no USB 3.0 header. The connector from the socket on the case is a 20-in connector. The USB 2.0 header has 9 pins. Two solutions were suggested:

  • A 20 pin to 9-pin converter; and
  • A PCI-E card with a 20-pin socket.

I chose that latter because it was USB 3.1 compatible, had a two-pin socket to maintain all of the functionality of USB 3.1 and added a USB-C external connector which I can use to rapidly charge my Google Pixel 2.
