The transient response should be better at 12V, and in both tests, the voltage on the 3.3V rail dropped below 3.2V. Moreover, the deviation is high on the 5V rail.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests. The 3.3V rail is low, though, close to the limit.
The 12V rail’s level is pretty high in the 200% load test compared to other similar spec PSUs.
