    Using a Molex to SATA adapter, can I plug the power cable into the connection in HD bay 4?

    That SATA connector on the backplane is a combo connector (data+power). A normal SATA power to Molex power cable will not attach properly. But if you have the right cable (with a combo connector) it should work.

    Obviously you will lose a HDD bay though. Everyone I know who has done this took the extra effort to use the optical bay power so as not to lose drive capacity.

    Well I just tried it and it works perfectly, I'm not concerned about losing the HD bay because I already have my SSD mounted in the 2nd optical drive bay.

    Oh that's great!

    I tried mine that came with my card and it didn't work. There was a rectangular protrusion that wouldn't connect with the combo connector on the SATA backplane.
