Cooler Master MasterWatt 550 Semi-Modular 550W 80 PLUS Bronze Certified Power Supply Unit

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.

Features
- Semi-Fanless up till 15% Load: Experience noise-free operation in normal PC loads under 15% output.
- Dual Forward and DC-to-DC Circuit Design: The Dual Forward and DC-to-DC circuit design offers reliability and stability especially significant in +3.3V and +5V output.
- 5 Years Warranty: The MasterWatt comes with a 5 year warranty.
- More Conductive PCI-e Cables: The MasterWatt uses 16AWG cables for PCI-e cables. Less resistance means better efficiency.
- 80 PLUS Bronze Certified: The 80 PLUS Bronze certification means MasterWatt is independently tested with efficiency of 85%.
- Durable LDB Bearing: Silencio technology combines sealed LDB bearings with quiet fan blades delivering a long lifetime of quiet cooling.
