That is a good PSu for your system, but an hxh550w would be cheaper and the same or better quality. Grab an hd7950 to go with it. MAKE SURE The GPU will fin in the case before you buy it.
Could you send a link for it, and does it have to be the exact dimensions for the PSU, because the one I currently have is 5.75 in width, 3.25 in height, and 6 in depth.
