Ok, couple things I would change the memory for DDR3 1066 to 1333 or faster. This looks like some good RAM http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314
for you. The power supply that you have listed is very good it is one of Eggxperts Tier 2 (very good) power supply and should provide all the power you need for this build. Overall I think that everything looks good.
