24 pin won't latch onto mobo

[Alexdale86]

Hello,
Antec true power 750
Asrock extreme 4
I have everything connected on this thing besides this freaking 24 pin power connector. I'm using so much force that it flexes the moboAntec even if I put my fingers behind it. Please please please someone help me. This is my very first build and all these parts are brand new. Thanks
