The Cooler Master 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.
