Hi, I am almost finished building my system wich have a Gigabyte r9 280 OC Windforce that will be powered by an XFX 750w Pro black edition. The gpu card has 2 power connection side-by side: an 8 PCI-E and a 6Pin, my question is , I have modular cable containing 8pin and 6 pin connection on each cable, do I need to connect 2 different cable from the psu , one going to the 8 pin and another cable for the 6 pin? I thought that the amperage would be hight on one cable, so I thought I should use a second cable.
