hi all, simple question really, i am trying to plug in my new seasonic platinum 860 v2 and the labeling on the psu is odd, for the 24 pin the side that goes into the psu has two pieces, one that's twenty pin, the other is like ten pin or something, bit lost! also there is two spots for cpu does it matter what one i connect to? thanks, oh and i have a sabertooth Z77 board if that makes any difference.
