CoolerMaster Power Supply MASTER WATT 650W Power Supply ATX 12V APFC SATA PCI Express 80+Bronze SemiModular Retail

The Master Watt is an 80 Plus Bronze power supply with an innovative semi-fanless mode. Under 15% load, the Master Watt 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, Master Watt is equipped with 16 AWG power cables, which reduces resistance, thereby increasing efficiency.



80 PLUS Bronze Certified

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



Durable LDB Bearing

Cooler Master 120mm Silencio FP fan combines sealed LDB bearings with quiet fan blades offering a long lifetime of quiet cooling.

A.Sealant on the The groove outside of the bearing helps to circulate the oil

B.Sealant on the bobbin and featuring the highest dustproof level IP6X

C.Recycle slot adds extra storage space for the oil

D.The shaft makes the oil flow by pumping it while spinning


Semi-Fanless up to 15% load

Master Watt 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.



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. The Master Watt uses 16AWG cables for PCI-e cables. Less resistance and better efficiency, providing you a safer user environment.
