EFFICIENCY GRAPH
Cooler Master MWE Bronze 550
INFO
This graph depicts the PSU’s efficiency throughout
its entire operational range. For the generation of
the efficiency and noise graphs we set our loaders
to auto mode through our custom-made software
before trying thousands of possible load
combinations
NOISE GRAPH
INFO
The PSU’s noise in its entire operational range and
under 30-32 °C ambient is depicted in this graph.
The X axis represents the load on the +12V rail(s)
while the Y axis is the load on the minor rails
