The transient response is mediocre overall. That said, the 12V rail has increased deviation at 20% load, where the main controller operates in the PWM region.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests. The 12V rail drops, low.
The 12V rail’s level drops low in the 200% transient load test.
