Quiet PSU with 140mm Depth

[frankhuzzah]

I just got a Fractal Design Node 304 and am looking at getting a new PSU to go into this build. While it does take a regular ATX PSU, to have a long video card in there, their literature says that it needs to be under 160mm in depth. So I'm looking for a quiet, efficient PSU to fit in there. I was looking at the Silverstone Strider series, the Seasonic S12II series, and the Corsair CX series. What's the general consensus around here?

My planned build is pretty straight forward:

i5 3470
SSD
AMD 7870 (Tahiti) or 7950

I'm not really looking at overclocking.

Thanks for the suggestions.
