Cooler Master MasterWatt is an 80 Plus Bronze power supply with an innovative semi-fanless mode. At 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. A 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 reduce resistance and thereby increase efficiency. 

80 PLUS Bronze Certified

The 80 PLUS Bronze certification guarantees that MasterWatt delivers an average efficiency of 85%.

Durable LDB Bearing

The Cooler Master 120mm Silencio FP fan combines sealed LDB bearings with quiet fan blades,offering long-lasting, quiet cooling.

●︎ Sealant in the groove outside of the bearing helps to circulate the oil

●︎ Sealant on the bobbin and featuring the highest dustproof level IP6X

●︎ The recycle slot adds extra storage space for the oil

●︎ The shaft makes the oil flow by pumping it while spinning

Semi-Fanless up to 15% load.

MasterWatt operates at 0dB under 15% load. Experience noise-free basic computing.

Dual Forward and DC-to-DC Circuit Design

More Conductive PCI-e Cables. The Dual Forward and DC-to-DC circuit design offers reliability and stability. This is especially significant in +3.3V and +5V outputs.
