The transient response with normal loads is good at 12V, but mediocre on the minor rails, especially at 3.3V, where the voltage levels drop well below 3.2V at both tests, failing in the second one.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests.
The 12V rail’s performance is good enough at high transient loads.
