Okay, this is my PcBuild I plan to buy instead of the cheaper one, if i get more cash. The questions are: I looked on the page and I saw that the recommended PSU is 750watts, but the estimated wattage in Pcpartpicker is 420~. Which one i trust and what psu i should get instead? The second question is: my case max gpu length is 300mm, but at the xfx page it says 29.5 :O. Will it fit or i should change/remove something. Thanks
