La seguente tabella contiene i livelli di ripple che abbiamo misurato sulle linee del SuperNOVA 850 G3. I limiti, secondo le specifiche ATX, sono di 120mV sul +12V e di 50mV sulle linee minori (5V, 3.3V e 5VSB).

---|---|---|---|---|---|
10% Load | 6.6mV | 3.0mV | 4.2mV | 8.0mV | Superato |
20% Load | 7.4mV | 3.5mV | 4.3mV | 7.7mV | Superato |
30% Load | 8.6mV | 3.5mV | 4.4mV | 10.6mV | Superato |
40% Load | 8.5mV | 4.6mV | 4.7mV | 10.8mV | Superato |
50% Load | 9.0mV | 3.8mV | 5.1mV | 10.6mV | Superato |
60% Load | 9.2mV | 4.3mV | 5.4mV | 10.7mV | Superato |
70% Load | 9.7mV | 4.4mV | 6.1mV | 12.0mV | Superato |
80% Load | 10.3mV | 4.5mV | 6.6mV | 10.2mV | Superato |

Immagini del ripple all'oscilloscopio
Le seguenti schermate mostrano il ripple registrato sulle linee principali dell'alimentatore (+12V, 5V, 3,3V e 5VSB). Maggiori sono le fluttuazioni sullo schermo, maggiore è il ripple. Abbiamo impostato 0,01 V/Div (ogni tacca verticale equivale a 0,01 V) come standard per tutte le misurazioni.
