Installing this morning that PCI-E card received in a period of 48 hours (thank you Amazon). Map snapped on the bracket connecting the connector to the molex power connector, it turns on, you install the driver provided in the enclosed mini-CD in the box, and found that everything was installed correctly, without any problem in Win7 environment. At first sight this material seems good, check for use. Looking for a card expandable to 4 USB 3.0 outputs (one never available too), I suppose backward compatible 2.0 and 1.1, I recommend this product "plug and play" laptopmate marketed by France, which s installs so could not be more simple.
