I recently built myself a new PC. My power supply came with two cables to hook from the power supply directly to devices, such as a hard drive or optical drive. I would like multiple hard drives, so I am in need of more of these cables. Can anyone tell me what they are called? I have tried to Google this with little luck. They are 6 pin on the power supply side (The black ports in the picture) and then SATA on the device side. Any help would be appreciated. Thanks!
