I'm thinking I'd like to add SATA capability to a non-SATA capable mobo. Is it simply a matter of buying something like this - http://www.newegg.com/Product/Produc...82E16816132007 - and installing it in your PC? I don't know anything about SATA except for the two different speeds/standards (1.5 vs. 3.0) so I'm kind of lost. The PSU is SATA power capable, and another question is if that is what I plug into the card (look at the card and I think you'll see what I mean)?

The way I picture it is I buy the card, install it, plug the SATA power into it that comes from my PSU, and than plug an external SATA hard drive into the PCI card. Is that all there is to it?
