Ive never needed the CD drive so I'm planning on taking that out and putting the new HDD in that space. The issue i'm having is with the sata power cable. I've read everywhere that the power cable goes to the PSU and you should have extra connectors with it, but for the HDD i already have it goes to a socket in the motherboard instead and I can't find any other power cables. So i'm wondering how to get the power cable to the the second HDD. This is a picture of the SATA data and power cables
