TEST RESULTS
RAIL STABILITY
We rarely see such rail stability from small power supply units especially when overloaded.
POWER CONSUMPTION
We squeezed a total of 612W from the PowerX 550W which is roughly 12% over its rated output.
NOISE LEVELS (SPL)
44.6dBA from 5-10cm away is not really much (so Young Li may be right when measuring dBA from over a meter away) but we have seen lower numbers in the past.
