Pros

Very quiet, and does a very good job venting heat.
Cons
None so far.
Summary
I got this PSU with the Nexus Breeze 400 case. It comes as a built in component of the case, as they used a patented airflow system to keep the electronics inside cool, while also using a lot of sound insulation to keep the PC quite.

So far the PSU has performed excellently. No problems with power delivery, or heat. It helps vent the case extremely well, especially considering how well sealed the case is. It also has a very quiet fan. Definitely worth a look, and in fact, if you're looking for a quiet case take a look and the Nexus Breeze 400, which NCIX also usually has in stock.
