The transient response is average at 12V and mediocre on the minor rails, especially at 3.3V, where the voltage level dropped below the limit, without any extra capacitance helping it out.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 3.3V rail drops low in the 200% load test.
The 12V rail’s transient performance is average compared to similar spec PSUs.
