Ok, so I'm currently building my new computer however, I've run into and issue that I can't figure out. The 12V header is what I assume the cables that come with my PSU label as CPU. However, this is a 8 to a double 4-pin cable. The headers on my mobo and psu are both 8-pin. Am I missing something here? Or do I need to get an 8 to 8-pin cable? Everything else so far has made sense except this.
my PSU is an EVGA 1000W G2 gold
my mobo is LGA 1150 ASUS z97-A
and for what is worth I have an i-7 4790k
