Ripple Measurements

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

Ripple suppression is very good, although not as good as in its twin brother, the Super Flower Golden King 1000W. Apparently two units that are made from the same production line do not share the same performance and this is clear proof of it. However with under 40mV ripple at +12V in the worst case scenario, 100% load, we are left quite satisfied and the same applies for the results that the minor rails registered. This unit, like all Platinum Super Flower units we tested in the past, is simply ripple proof.

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.
