Update: Found this deal as well. This unit has quite a higher wattage capacity and usually sits at the $80 mark, so getting it for a flat $50 from Amazon is a pretty great option as well:

The Nex isn't EVGA's best units, but they still get decent reviews. For your specs it would be more than enough and I'd personally choose it over the CX I mentioned first.
Edit: To answer your question, the EVGA unit you linked is about neck-in-neck with the CX in terms of quality. EVGA models vary quite a lot in quality, so you really need to know them model by model to get a good one.
