To the best of my knowledge 2 cables are required to service a SATA device.1.A SATA data transfer cable and 2. A SATA power supply cable. Due to the proximity of these connections on the hardware device HDD,DVD,CD etc. it is possible that the 2 required plugins may be combined on one cable (but will still need to physically go into the 2 separate connectors on the device. I am still not sure what your confusion is about the "SATA connector"? If you remember that 2 things are required =data transfer and power then obviously at data cable alone or a power cable alone will not suffice. There are a multitude of configurations of the 2 above cable options (including 2 different types of SATA ). It depends on your physical requirements (IE; whether a right angle plug is needed or not). The length of the cable to conform to computer attachment points. The availability of SATA power connectors from the PSU (a problem in my case--requiring an adaptor). I do hope i am being of some assistance but to tell the truth i am having some problem still trying to get a handle on what it is your trying to determine.Have you talked to Dell about this?truenorth
