XPS 9000 hard drives

I installed two SATA internal hard drives in my Studio XPS 9000 computer. Now, I cannot locate the power connectors for these drives! Are these in the case and I am too stupid to locate them, or is this something Dell did not include and I have to purchase them separately?

I never ran into this problem with my other computer. Hooked them up, plugged them, formatted them and they were good to go.

Thanks for any help.
