I am not an expert, but I keep reading that the Corsair CXV2 is not so good. The first gen of Corsair CX were good but they lowered the quality of parts with the V2... (from what I've read, correct me if I am wrong). Anyway, if I were you I would at least get a 80+ bronze PSU in there.

You can also look at Antec and XFX power supplies, they are also really good brands.
