PCI-E to Dell N750P PSU Help

[Ftlkid24]

I ordered these off the internet and I don't know how to connect them.  Can anyone help me to where to plug these in?  Am I missing a piece?

Hey,

These links have the info about the pins and connectors. You aren't missing anything, just push your plug over two of the connectors (they are in pairs - 6 in total).
