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,MasterWatt is equipped with 16 AWG power cables,which reduces resistance,thereby increasing efficiency.
