I bought this card to have several USB 3.0 ports on my desktop computer with a PCI Express 1.0 port. After carefully dusted the PCI Express connector of my board (did not detect the card after 2 trials), the card was detected and installed by Windows 7. It should be noted that the card is properly connected if a red LED s' lights on it when the computer is started. If the LED is not lit, the adapter is not properly connected (not detected). Of course, it will download and install the latest USB 3.0 drivers available on the website of Inateck [...], otherwise they use the CD-ROM provided. After restarting the computer, I also has 4 USB 3.0 ports (160MB / s), which are three times faster than my USB 2.0 (40Mb / s). These tests were performed with a Samsung SSD and USB 3.0 enclosure FE2002 Inateck. This card good price / quality ratio is very easy to install and is compatible with older PCI-E 1.0 ports. By cons, he lacks a leaflet in French for those who are angry with English.
