Hello, I am dang near completion of my first ever gaming pc build. One of my last remaining steps is connecting my storage drive. I am planning on using a single external SSD as the primary storage drive as well as for the OS. It is an HP S700 500GB SSD. However, since I bought both my PSU and my motherboard used, neither of them came with any of the cables that I presume would normally be used to hook up this drive. I am at a loss as to exactly which cables I need? For this specific SSD, do I need both a cable that connects the SSD to the PSU, as well as another cable that connects the SSD to the motherboard? If so, where can I acquire said cables? And why does the drive have SATA III in the name, but on the back of the drive it says that the interface is SATA 6.0gb? I know this is a lot of questions, but I am new to all of this. Thank you in advance for any help!
