Did you turn on the computer from the rear I/O switch?

Yes I turned the switch on the power supply, I have tested the power supply and I was able to get my fans to turn on by testing the green wire and a ground on the connector coming from the psu, but when I connect it to the Mobo and push the power button nothing happens.

Try reseating the RAM and video card.

Speaking of RAM, why no mention?

I am running 2G right now, just so I could set all the drivers and bios up, my new ram is coming tomorrow. Just for verification, the video card shouldn't be the issue, I could have it out and the mobo should still run I would just have no picture, I don't know if that is the same for the ram.

Sounds like it. Did you install the case stand offs in the appropriate holes?
