Summary: Great card. Cheaply built, but it works well so who cares? (connect the power cable before installing in PCIe slot or you make break the plug slot)Didn't bother with the install disk and got the drivers directly from the website.
Summary: Installed the card and software, worked 36 hrs, then failed. Had to uninstall software and remove-reinsert card, re-install software, worked 24 hrs, then quit. Did this 4 more times, and returned it for a refund.
Summary: I have installed this PCIe card on the older motherboard to make the USB 3.0, 4 channels available. Installation was very easy, it works fine under Windows 7, I keep the USB 3.0 Passport disk permanently connected. I am very satisfied with the VisionTek card.
Summary: Unlike others, mine came with a Molex to SATA power adapter. The driver installed from the CD and my SanDisk Extreme USB-3 thumb drives finally operated at read speeds of 150 Mbs. Then I tried some USB-2 thumb drives. Problems.
