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.
Durable LDB Bearing
Cooler Master 120mm Silencio FP fan combines sealed LDB bearings with quiet fan blades offering a long lifetime of quiet cooling.
o Sealant on the bobbin and featuring the highest dustproof level IP6X
o Sealant on the The groove outside of the bearing helps to circulate the oil
o Recycle slot adds extra storage space for the oil
o The shaft makes the oil flow by pumping it while spinning
Dual Forward and
DC-to-DC Circuit Design
The Dual Forward and DC-to-DC circuit design offers reliability and stability. This is especially significant in +3.3V and +5V outputs.
More Conductive PCI-e Cables
The MasterWatt uses 16AWG cables for PCI-e cables. Less resistance and better efficiency,providing you a safer user environment.
