Hello, I plan on building a gaming PC, but I don't understand why the semi-modular Corsair TX750m PSU has a build in cable for the motherboard and CPU (8pin), but still says 4+4 CPU and 6+2 pcie. I looked at the picture of the PSU on amazon and I would like to know if I can connect it to the MSI rtx 2070 super gaming x trio. The graphics card needs two 8 pin connectors but how do I connect them? There are two 8 pin connections on the TX750m, so do I use them both? If yes, which cable do I have to use and why is there written CPU 4+4?
