From what I've been reading the vga cables go into the graphics card but my graphics card came with two six pin power cables which fit perfectly into the graphics card. The six pin connects to a cable that plugs into the Sata/perif on the power supply. Do I not need the two vga cables if the six pin is plugged in? I don't know if this helps but I have a GeForce Gtx 970 graphics card and a evga 550 GS power supply
