The FSP I listed is a great unit so far. Been running it all day long in the front office. I replaced a generic 400 wat unit that was just too noisy. The FSP is much more quiet and my system runs very cool and quiet now.
I would go for the Seasonic S12 330 if low noise is a priority. 330W may seem small, but it is more than enough for your system and it is also more energy efficient than the FSP PSU that was recommended.
