Cooler Master MPX-5501-AMAAB User Manual
MasterWatt 550
Semi-fanless Modular 80 PLUS Bronze Certified Power Supply
The MasterWatt is a 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 are employed to keep the
voltage stable in all conditions. For increased performance,
MasterWatt is equipped with 16 AWG power cables, which
reduce 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.
