Cooler Master MasterWatt 550 - power supply - 550 Watt

The MasterWatt is an 80 Plus Bronze power supply with an innovative semi-fanless mode. The MasterWatt fan remains idle, offering zero dB. 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.
