the corsair CX and VS lines are especially weak. id recommend something from Antec, SeaSonic, or XFX.
Also save up more money for a better GPU. Not that the 760 is bad, its just no point in a OC'd CPU when the GPU isnt really pushing it all that hard. If cost is a big factor you will get a better performance per dollar with an ATI card (r9 series).
You could budget it from the case price (get a cheaper case maybe). The R4 is a great case but its a larger mid size chassis, if you are okay with that. The Corsair Spec 01 is a great case for the price and has a big window too and doesnt take up too much desk space.
