I bought a new SSD for my desktop computer to supplement my 2 TB HDD, but when I opened the case, there was only 1 free connector inside.
Based on my understanding, HDDs and SSDs need 2 connectors - one for SATA, and one for power. In the picture, the preinstalled HDD (right side) has 2 connectors connected to it, while the free slot only has one connector (left side).
Do I need to purchase an extra cable for my SSD? If so, which one am I lacking, the SATA cable or the power cable?
Update: If it helps, my desktop is a Dell XPS 8910 Special Edition.
The SSD I'm installing is a SanDisk Ultra Plus 120GB SATA III Internal Solid State Drive.
