You need a 500+ PSU Did you look at the requirements?

You don't give enough information so follow manufacturers specs as I said previously. Power consumption problem is not a "bottle neck" IMO. You are using the wrong terminology. If you want to provide enough power to the video card follow the manufactures specs. If you are going to err do it on the high side not low.
