Sabertooth x79 not powering on


Apr 26, 2012
I'm fairly new to the pc building and I am trying to build with a Sabertooth x79 mobo. I have 2 sticks of Corsair vengeance 8GB DDR3 1600 ram and when I plug the board into the power supply and try to power the board up, all I get is the green standby light. Granted I haven't plugged in the CPU or a video card, but shouldn't I get some other lights coming on or the on board fan spinning if its turning on properly? I must be missing something basic. The two power cables are plugged in properly.
