I want to go with Corsair for the brand as I hear really good things about them. I just cannot, for the life of me, figure out what wattage I need!

Also, I do not plan on overclocking at all and if there are tips, formulas or references that may help me with this issue in the future they would be greatly appreciated. My current combine carts from Newegg/Tigerdirect are as listed below.

Thank you in advance for your time and consideration!
