Here is what Cooler Master has to say about their MasterWatt Bronze PSUs:

The MasterWatt is an 80 Plus Bronze power supply with an innovative semi-fanless mode. Under 15% load, the MasterWatt fan remains idle, offering zero dBA. When demand for power increases, a gradual fan curve provides measured cooling with little to no noise at any output level. Dual forward / DC-to-DC topology is employed to keep the voltage stable in all conditions. For increased performance, MaterWatt is equipped with 16 AWG power cables, which reduce resistance thereby increasing efficiency.
