Why you can trust Tom's Hardware
To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the AX1600i's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).
The AX1600i's ripple suppression is amazing! Besides super-tight load regulation, this digital platform also allows for DC rails that are clear of ripple.
Ripple Oscilloscope Screenshots
The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.

Excellent review , thanks!Reply
Excellent review. But I cannot view the video's, what format do you use?Reply
all of we need is 500w class digital titanium++ psu with this advance technology..Reply
Well, pc is much more efficient right now..
I wonder how many people will use it anyway...
Videos working fine here.Reply
PCs are more efficient, however graphics cards once pushed are not and many users tend to overclock their GPUs. Moreover, those units are intended for multi-GPU systems.
Do you do you fan and noise measurements with 110V or 220V? That should make a difference in this case at least.Reply

115V but I also take noise measurements with 230V because of Cybenetics.
115V: 23.25 dB(A)
230V: 23.29 dB(A)
Specifically at what point does it change from passive to active cooling using either 110V or 220V?Reply
please check the CL noise graph of the review.Reply
Primary DSC should be NXP Freescale MC56F8236Reply
Secondary DSC is Texas Instruments UCD3138064A
