The transient response with normal loads is average at 12V, decent at 5V and 5VSB, and mediocre at 3.3V, where the rail’s voltage drops well below 3.2V at both tests.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests.
The 12V rail’s performance is not competitive at high transient loads. I cannot call it bad or even mediocre, because it is close to the category’s average voltage level.
