Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of FTY1000W. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

Ripple Measurements OCZ FTY1000W
Test	12 V	5 V	3.3 V	5VSB	Pass/Fail
20% Load	12.0 mV	4.7 mV	13.9 mV	6.1 mV	Pass
40% Load	13.6 mV	7.6 mV	16.3 mV	8.1 mV	Pass
50% Load	15.6 mV	8.1 mV	17.0 mV	8.8 mV	Pass
60% Load	19.6 mV	8.6 mV	17.2 mV	9.3 mV	Pass
80% Load	26.1 mV	8.8 mV	17.3 mV	10.4 mV	Pass
100% Load	36.4 mV	9.7 mV	19.0 mV	13.5 mV	Pass
Crossload 1	19.2 mV	11.9 mV	17.9 mV	10.8 mV	Pass
Crossload 2	32.6 mV	6.2 mV	16.3 mV	11.2 mV	Pass

Ripple suppression at +12V and 3.3V is very good while at 5V and 5VSB it's excellent. As it seems Sirfa did a very good job here since its ripple suppresion is now at the top-notch levels of Delta, Seasonic and Super Flower. After all gamers need as low as possible ripple for cleaner DC outputs and far less stress on their system components, right?

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.
