Transient Response
20% Load – 20ms
| Voltage | Before | After | Change | Pass/Fail |
| 12V | 12.053V | 11.965V | 0.73% | Pass |
| 5V | 5.013V | 4.932V | 1.61% | Pass |
| 3.3V | 3.319V | 3.211V | 3.25% | Pass |
| 5VSB | 5.005V | 4.959V | 0.91% | Pass |
50% Load -20ms
| Voltage | Before | After | Change | Pass/Fail |
| 12V | 12.015V | 11.928V | 0.73% | Pass |
| 5V | 4.986V | 4.916V | 1.40% | Pass |
| 3.3V | 3.290V | 3.171V | 3.62% | Pass |
| 5VSB | 4.954V | 4.913V | 0.83% | Pass |
It makes a huge impression that the transient response deviation at 12V is the same at both 20% and 50% starting load. In any case, the average deviation is pretty low. The 5V and 5VSB rails also perform well here, but I cannot say the same for 3.3V, which drops its voltage below 3.2V.
Transient Response ATX v3.0 Tests
The PSU passes all ATX v3.0 transient response tests.
The 12V rail’s level drops too low in the 200% transient load test.
