MasterWatt 550 Watt 80 PLUS Bronze Certified Semifanless Modular Power Supply
The Cooler Master Watt Bronze 550W is a modular 80 Plus Bronze certified PSU with a semi-finless mode. Under 15% load, The masterwork Bronze fan remains idle, offering zero dB. When demand for power increases, a gradual fan curve provides measured cooling with little to no noise at any output level. Dc-to-dc topology is employed to keep the voltage stable in all conditions. For increased performance, The masterwork Bronze 550 Watt is equipped with 16 AWG Pie cables, which reduce resistance thereby increasing efficiency.
Features:
- 550W semi-modular ATX power supply
- Semi-finless up till 15% load
- 80 plus bronze certified
- Temperature controlled 120 millimeter fan with dustproof LDB bearing
- Dc-to-dc circuit design for stable voltage output
- Thicker 16AWG Pie cables to support the latest graphics cards

Manufacture Description
80 PLUS Bronze Certified
The independently tested 80 PLUS Bronze certification guarantees that MasterWatt delivers a typical efficiency of 85%.
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 thicker 16AWG PCI-e cables. They provide less resistance increasing efficiency and safety.
