The transient response deviations are low, especially on the minor rails. Nonetheless, the 3.3V rail drops below 3.2V in these tests, which wouldn’t be the case with an increase in its nominal voltage.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 3.3V rail drops low in the 180% and 200% load tests.
The 12V rail stays high enough, but there is room for improvement in the 180% and 200% transient response tests.
