Ripple Measurements
In the following table you will find the ripple levels that we measured on the main rails of HALE82 850M. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

Test | 12 V | 5 V | 3.3 V | 5VSB | Pass/Fail |
20% Load | 13.9 mV | 6.8 mV | 5.7 mV | 7.4 mV | Pass |
40% Load | 18.8 mV | 7.3 mV | 8.2 mV | 8.2 mV | Pass |

80% Load | 21.7 mV | 10.1 mV | 11.9 mV | 10.4 mV | Pass |
100% Load | 32.0 mV | 10.3 mV | 13.0 mV | 11.2 mV | Pass |
Crossload 1 | 14.6 mV | 9.5 mV | 6.3 mV | 16.4 mV | Pass |
Crossload 2 | 30.5 mV | 8.5 mV | 8.3 mV | 9.6 mV | Pass |
Ripple/noise suppression is excellent at all rails/load combinations. At worst case ripple at +12V rail reaches one quarter of the limit while the minor rails stayed at about one fifth of the respective limit. This kind of performance easily competes with much more expensive units which belong in the high-end category.
Ripple at Full Load
In the following oscilloscope screenshots you can see the AC ripple and noise that the main rails registered (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the oscilloscope's screen the bigger the ripple/noise. For all measurements we set 0.01 V/Div (each vertical division/box equals to 0.01V) as standard.
