The need for 8 SATA connectors may limit your choice a little, particularly if you need a 9th one for the optical drive. The Corsair web page lists which connectors come with which PSUs (several of them do have at least 8 SATA). I believe that they sell additional cables for their modular units, if necessary, or you could always use one Molex to SATA converter.

Or possibly use a sata power splitter cable
