StarTech.com 4 Port PCI Express USB 3.0 Card - 2 External & 2 Internal - SATA Power

This PCI Express USB 3.0 card offers a cost-effective upgrade that lets you add four USB 3.0 ports to your computer through a PCIe slot. It offers two external ports plus two internal USB 3.0 headers to help adapt your desktop or server to support a variety of USB 3.0 devices.

Flexible and convenient port design

For added convenience, the card integrates two external USB 3.0 ports, so you can plug in more devices such as external hard drives or printers.

Simple installation and supports older devices

Plus, itfeatures a dual profile design that fits in standard or low-profile cases, so you can rest assured it will fit in your small form-factor system if needed.

Connecting older peripherals isn't a problem either. So, there's no need to purchase new devices since the adapter card is backward compatible with your USB 2.0 and 1.x technology.
