Price: $60 Canadian

Introduction:
A couple weeks ago we had the opportunity to look at the Coolmax 480W fan less power supply. This supply was good for those who had a case fan near by to maintain air flow, but really heated up for those with no fans such as a liquid cooled system.
Today we have the opportunity to look at the Coolmax 400W ActivePFC EPS power supply. This power supply has a very large and extremely quiet 120mm cooling fan. In addition to this power supply being quieter, the fan is also 3 way adjustable to best suit your noise requirements. Will this power supply perform as well as it looks? Read on!
