Beware constraints

Article of bone quality immediately recognized vista / windows 7 without even drivers on rather old maps (contrary to what is said on the website of Asus, but this may be related to the points below)
But:
- Consumes a lot, especially on the part USB3. No external power socket (like graphics cards and some controllers cards) and so is the motherboard which must ensure sufisamment power on ports. Moreover, this card, fully loaded on a USB3 device and 2 SATA drives, made toast the PCI-Express port on a Gigabyte 780G old enough (port unusable). By cons, on a recent map Asrock P67 Extreme3, no power concern.
- As a result of the high consumption, it heats a lot and is literally boiling in charge. Beware refroidissment. Again, I had to stick a chipset heatsink on the chip USB3 and the central controller.
- More hassle, it is x4 and PCI except on Asus motherboards that have a specific x4 port, you have to put it on the 2nd or 3rd PCI Express x16 based motherboard if you have a graphics card on the 1st. Therefore, with the exception that some mothers high-end cards, PCI Express port on your graphics card switches to x8 instead of the original x16. resulting in a loss of performance, certe minimal.
Personally, if you have 2 PCI Express x1 ports free, I advise you rather to buy 2 separate cards, one for SATA III and one for USB3 finally avoid small problems mentioned above.
