GPU doesn't have a PCI-E connector

[Scarss]

First time building a PC, following a YouTube tutorial step by step. I was plugging in all my power supply cables when I got to the part where I needed to plug in my GPU. I have the PCI-E 6 pin cable but nothing on my gt730 to connect it to. Maybe its just something I'm missing as a first time builder?

That gpu doesn't need supplemental power from the psu, it takes it all from the pcie slot on the mobo, so just slot the card into the motherboard, and you're done.
