First time building a PC. I bought a Titan X graphic card, and I'm stuck not knowing how to connect the cables. I know Titan X requires 8 pin + 6 pin connector for power, but the thing is I don't know if I should use a Y cable (8pins from psu to Y cable 6+8) or two separate cables 6 pins from psu to 6 pins graphic card and 8 pins from psu to 8 pins graphic card.
