Ripple Measurements
To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the SF600's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).
Test | 12V | 5V | 3.3V | 5VSB | Pass/Fail |
---|---|---|---|---|---|
10% Load | 12.7mV | 6.4mV | 9.1mV | 6.3mV | Pass |
20% Load | 15.9mV | 7.0mV | 9.0mV | 6.3mV | Pass |
30% Load | 16.4mV | 7.7mV | 9.5mV | 6.6mV | Pass |
40% Load | 17.1mV | 7.5mV | 11.0mV | 6.7mV | Pass |
50% Load | 19.4mV | 7.9mV | 10.5mV | 7.4mV | Pass |
60% Load | 23.2mV | 8.2mV | 11.1mV | 7.8mV | Pass |
70% Load | 22.4mV | 8.8mV | 13.4mV | 7.9mV | Pass |
80% Load | 23.0mV | 10.7mV | 15.2mV | 8.9mV | Pass |
90% Load | 24.5mV | 11.7mV | 17.2mV | 8.7mV | Pass |
100% Load | 24.2mV | 13.3mV | 21.3mV | 10.7mV | Pass |
110% Load | 25.7mV | 13.7mV | 21.8mV | 10.7mV | Pass |
Cross-Load 1 | 16.3mV | 12.0mV | 18.8mV | 8.9mV | Pass |
Cross-Load 2 | 25.7mV | 11.6mV | 13.7mV | 9.4mV | Pass |
Ripple suppression is very good, especially when we consider the SF600's compact dimensions that invariably limit the platform's design. Great Wall did a great job here (under Corsair's guidance, of course).
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 0.01V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.
