Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of HCP-1200. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V & 3.3V).

Ripple Measurements
Test	12 V	5 V	3.3 V	Pass/Fail
20% Load	5.2 mV	6.8 mV	6.2 mV	Pass
40% Load	6.2 mV	9.8 mV	10.6 mV	Pass
50% Load	7.0 mV	10.2 mV	11.0 mV	Pass
60% Load	7.6 mV	10.4 mV	11.2 mV	Pass
80% Load	8.4 mV	12.4 mV	14.2 mV	Pass
100% Load	9.4 mV	14.2 mV	17.8 mV	Pass
Crossload 1	6.2 mV	8.8 mV	7.2 mV	Pass
Crossload 2	8.4 mV	13.6 mV	17.2 mV	Pass

Ripple at minor rails is low and among the lowest we have seen. What amazed us, actually we are still trying to pick our jaw off the floor, is ripple suppression at +12V. Even with full load it didn't exceed 10mV. This is by far the best performance we have seen till today. This alone is more than enough to make us forget the loose voltage regulation at 3.3V and praise the performance of HCP-1200. If Dlata continues to evolve their designs then in the near future we won't need an oscilloscope for PSU reviews, since ripple measurements will be unnecessary.

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). The bigger the fluctuations on the oscilloscope's screen the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals to 0.01V) as standard but sometimes we are forced to use 0.02 V/Div, meaning that the fluctuations will look smaller but actually this wont be the case.
