Ripple Measurements
To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the G-450'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 |
|---|---|---|---|---|---|
| 1 | 8.1mV | 6.8mV | 9.7mV | 8.5mV | Pass |
| 2 | 8.8mV | 8.0mV | 9.8mV | 10.1mV | Pass |
| 3 | 10.8mV | 7.3mV | 10.5mV | 11.4mV | Pass |
| 4 | 12.0mV | 8.0mV | 11.0mV | 12.2mV | Pass |
| 5 | 13.0mV | 8.6mV | 10.8mV | 14.0mV | Pass |
| 6 | 15.1mV | 9.9mV | 11.1mV | 13.9mV | Pass |
| 7 | 17.0mV | 11.5mV | 11.7mV | 15.2mV | Pass |
| 8 | 19.2mV | 19.9mV | 12.6mV | 15.7mV | Pass |
| 9 | 21.4mV | 20.1mV | 13.1mV | 16.3mV | Pass |
| 10 | 24.7mV | 21.9mV | 13.2mV | 18.0mV | Pass |
| 11 | 26.4mV | 23.7mV | 13.4mV | 18.4mV | Pass |
| CL1 | 11.1mV | 9.7mV | 8.7mV | 12.9mV | Pass |
| CL2 | 23.4mV | 18.4mV | 9.2mV | 16.4mV | Pass |
Ripple suppression is excellent on all rails; Seasonic did a fine job here. Some users may say that Super Flower's implementations are better in this area. However, we are satisfied with the G-450's ripple suppression.
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.
