Im thinking its the psu but also thinkin it may be my mobo. In the process of trying to rma my psu through the corsair site but cant figure how to register my psu... guess i gotta call em.
It really sounds like a flaky "crowbar" circuit in your power supply. It's supposed to turn the power supply off when voltage or current problems are sensed. And as long as it senses a problem it is designed to remain off. It might hang in this off state. But unplugging the A/C input power cable for a short while should allow it to reset itself. 6 hours is just wrong. I agree it could be your MB or even worse both your MB and PSU after all this thrashing around.
