Unless it's crappy, no. Your cpu likely only pulls about 30w, the GPU will likely only pull about 70w, and everthing else another 30w. I've run an Core 2 Duo E7500 + 460, which uses more power than your system on a meh 300w. I wouldn't recommend it being the final solution, but good enough for testing.
I would definitely return the PSU, regardless of if it's the problem.
