If you don't mind forking out a little extra money for the psu and the ram then I say go ahead. Your PSU will future proof you in case you ever add more stuff, same with your ram. I have the same ram and the only reason I got 16GB was because it was only $89. Corsair PSU last for a long time too and you won't have to upgrade that until it dies probably. Parts all look good to me, go for it!
