I'm not sure how much wattage my new build will require. PCPartPicker's estimated power consumption was 477 watts, but I'm not sure how accurate that really is. Based on this calculation, I'm loosely planning on purchasing a Corsair 860W Modular Power Supply, just so I have plenty of room for overclocking or future additions to my build. If anyone can help my find out how much power my system will need, that would help me out tremendously.
Here's my build:http://ca.pcpartpicker.com/user/JordanK/saved/#savedbuild_579501
