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.

Main Features:

  • 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 PCIe Cables - The MasterWatt uses 16AWG cables for PCI-e cables. Less resistance and better efficiency, providing you with a safer user environment.
