For the category’s standards, the transient response is decent at 12V, average at 5V, and mediocre at 3.3V, where the PSU fails in the second test. As for the 5VSB rail, who cares? From the moment it keeps its voltage within the specified range, everything is fine there.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 3.3V rail drops below 3.2V.
The 12V rail performs well here.
