Alright .. get whatever your budget permits but keep in mind whatever your rig might consume with upgraded/added components it's always better to go in for a higher spec PSU - say your whole rig will consume around ~500w and to be safe go for a PSu which can deliver 600-650w
BTW, there's two more PSus you might consider ie Corsair TX650v2 @ ~5.5k or TX750v2 @ ~6.2k
