Transient response (transient behavior)
The transient response is good at 12V, average at 5V and average at 3.3V.

Transient Response ATX v3.1 Tests
The power supply passes all ATX v3.1 tests for transient response, but the voltages of the 12V and 3.3V rails drop relatively sharply.
The performance of the 12V rail is average in these tests.
