I'll be looking at one case later with a Sata 1 drive there. You have two options for power on those with the standard molex or sata power connection. The sata to ide converter cables will work just as well as adding in a separate controller card.
The hardware limitation still see a lack of any real gain from the sata bus while a controller will allow multiple drives if you want to expand later. Your other option is simply to return that for an ide model.
