Anandtech did a review of the 430 watt model. JonnyGuru's review was much more favorable (and he actually reviewed the model being offered in this thread). I have the 430 watter in my HTPC and it is very quiet. My HTPC is geared towards relatively quiet operation and adding this PSU in place of an Ultra V-Series 500 watter with a 120mm fan didn't result in any added noise whatsoever.
