The MasterWatt is an 80 Plus Bronze power supply with an innovative semi-fanless mode.
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.
80 PLUS Bronze Certified
The 80 PLUS Bronze certification guarantees that MasterWatt 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.
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
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.
