Ok thanks for the clarification on the GPU.
The box does say the CPU ones are EPS 12v 8 pin (4+4). It gives me 2 of these cables
The PC needs one 8 pin which is easy enough. but it also needs an additional 4 pin. I separated the 8 pin into 2-4 pins and both the 4 pins would plug into the motherboard. Does it matter which plug i use of the 2 4 pins?? I'm assuming not but want to make sure..
