CoolerMaster MPX-5501-AMAAB MasterWatt 550 Watt Hybrid Modular ATX PSU/Power Supply

n 
n
nThe 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.
n
n80 PLUS Bronze Certified
nThe 80 PLUS Bronze certification guarantees that MasterWatt delivers an average efficiency of 85%.
n
nDurable LDB Bearing
nCooler Master 120mm Silencio FP fan combines sealed LDB bearings with quiet fan blades offering a long lifetime of quiet cooling.
n
nSemi-Fanless up to 15% Load
nMasterWatt Operates at 0dB under 15% load. Experience noise-free basic computing.
n
nDual Forward and DC-to-DC Circuit Design
nThe Dual Forward and DC-to-DC circuit design offers reliability and stability. This is especially significant in +3.3V and +5V outputs.
n
nMore Conductive PCI-e Cables
nThe MasterWatt uses 16AWG cables for PCI-e cables. Less resistance and better efficiency, providing you a safer user environment.Features• Semi-Fanless up till 15% Load: Experience noise-free operation in normal PC loads under 15% output.
n• 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.
n• 5 Years Warranty: The MasterWatt comes with a 5 year warranty.
n• More Conductive PCI-e Cables: The MasterWatt uses 16AWG cables for PCI-e cables. Less resistance means better efficiency.
n• 80 PLUS Bronze Certified: The 80 PLUS Bronze certification means MasterWatt is independently tested with efficiency of 85%.
n• Durable LDB Bearing: Silencio technology combines sealed LDB bearings with quiet fan blades delivering a long lifetime of quiet cooling.
