Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of HCP-1000. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

Ripple Measurements Antec HCP-1000
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	15.3 mV	16.1 mV	9.6 mV	11.6 mV	Pass
40% Load	18.2 mV	16.5 mV	10.0 mV	12.8 mV	Pass
50% Load	18.4 mV	16.7 mV	10.3 mV	13.1 mV	Pass
60% Load	19.1 mV	17.1 mV	10.8 mV	13.5 mV	Pass
80% Load	19.2 mV	17.3 mV	12.7 mV	14.3 mV	Pass
100% Load	19.6 mV	17.6 mV	13.0 mV	14.5 mV	Pass
Crossload 1	13.6 mV	14.5 mV	12.1 mV	12.9 mV	Pass
Crossload 2	16.4 mV	29.2 mV	15.8 mV	11.9 mV	Pass

If there is one specific area in which Delta implementations cast (lots of) shadow on their opponents this is of course ripple suppression. With only 20mV max ripple at +12V any further comments are unnecessary. This platform is simply ripple proof. At CL2 test you will notice that ripple on the minor rails is higher due to some repeated oscillations which are clearly shown in the respective scope screenshots. Nevertheless we are quite sure that these oscillations are the product of the excess heat, to which we exposed the unit while we were conducting the specific test.

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.
