Easily add USB 3.0 functionality to your PC with this Insignia™ NS-PCCUP53 PCI Express interface card that offers data transfer rates up to 5 Gbps per port and is backward compatible with USB 2.0 and 1.1 devices for flexibility.
I purchased this item because there was no mention of the requirement for a 4 pin SATA power connection. I was planning to use it with a self powered USB 3.0 Back Up drive. My computer is a rather minimal HP s561091 without a break out for a 4 SATA power connection; hence no way to even use a Y connector.
