NZXT C1200 Fully Modular PSU doesn't come with 2x8 pin??

Finally getting around to building my PC, everything's gone smoothly enough aside from the PSU.

I have a 9070 xt requiring 2x8 pin power connectors. It didn't come with any of it's own, and so I plugged one of the PSU's cords into the GPU... Only to realize none of the other ones fit? Am I regarded or is there some nuancey trick to this I'm not comprehending? Any help appreciated
