So i have just bought a new mobo and a new cpu( mobo- z87k, cpu-4790k) and i wired everything up except an 8 pin slot. I put a 6 pin and a 2 pin cable in the slot then i pressed the ON button and then i tried to start the pc but nothing happened. If I try to run it without any cables in the 8pin
The fans spin for a second and that's it.
