Need help picking a PSU

Need some help picking out a PSU. I was looking at this one:

If you guys have better ideas, let me know.

Here's what I'm running:

Intel Core i3

Radeon HD 7770

ASRock FM2A85 Extreme4

EVGA graphics card (7770)

6GB RAM

Scythe Katana 4 CPU cooler

There’s no need to keep starting new threads about this; we already have a dedicated master thread right here.
