If you look at this list of YOUR parts I complied, the price looks a little high for what you can get otherwise. PCPartPicker part list: http://pcpartpicker.com/p/AFAu
Also, I agree that you might want to look into a different PSU, and it wouldn't cost that much more to jump up in quality.
In fact this 650W Corsair PSU would be even less ($50, or $30 after MIR), but it isn't modularhttp://www.newegg.com/Product/Product.aspx?Item=N82E16817139020
Modular Seasonic (great) $94 inc. shippinghttp://www.newegg.com/Product/Product.aspx?Item=N82E16817151106
