There are 3 SATA ports on this machine. 1 is a SATA (ODD) for an optical drive, and 2 others are SATA 3. Current drive configuration is SSD in M2 slot, 3.5" in SATA 3 port, and optical in ODD port. One SATA 3 port remains empty though there is no connector on power cable to power extra drive. I think it's just a matter of replacing power wire with one with 2 connectors, but I'm not sure if PS will handle an extra drive. Any thoughts on this would be appreciated.
