The 1000 Watt PSU is way too much for what you have here, 700 watts would have been more than enough considering that you don't even have crossfire GPU's. Although a PSU only uses what is required, there is a brief moment during boot up where it uses the maximum power output to ascertain the power requirements of the system so you need to be aware that the total output will impact on the powerboard that you are using if not the mains power outlet, don't have other high power electronics on the same powerboard.
