Look at the stability of the 5V line, that's pretty much as good as it gets! Great job here Sunbeam. The 12V line fluctuates a bit more, but is far from reaching critical levels.


Just like on the last Sunbeam PSU, when I measured the ripple voltage I noticed that there were two distinct ripples of different frequency. The first image shows ripple at 5 mV/div, 5 uS/div which is the way we usually test. You can clearly see the ripple with 14.4 mV amplitude.
On the second image we have ripple measured at 5 mv/div, 1 ms/div, so basically zoomed out by factor 20 on the horizontal time scale. Here we also see a nice ripple curve. I would say this is nothing bad, it was just something I noticed during testing. It has probably to do with the way how this PSU is constructed and seems to be common to Sunbeam's high-end PSU lines since we have seen it on our Ensemble 1200W review too.

Standard deviation 12V	12.59
Standard deviation 5V	2.35
Standard deviation 3.3V	7.47
Power Factor	0.97
Ripple Voltage 12V	14.4 mV
Power Efficiency @ 320 W	80% (320W:400W)

Standard deviation is a statistical term, which tells how far away from the average the measurements are. In other words it's the average of the average.
A large standard deviation indicates that the data points are far from the average and a small standard deviation indicates that they are close within the average.


Sunbeam claims 80+ efficiency, which is spot on with our measurements.
