It's never a motherboard problem, and hardly a graphics card problem. Power problems = Power Supply problems. First, how much watts is your PSU? Second, if you're sure it's more than enough to run your PC then it must be a defective unit, return it from where you ordered it and ask for a new one.
Its an xfx 550w pro edition. Definitely could be defective or underpowered I'm going to disconnect my fans and drives and see if that will free up the necessary power to run the GPU.
