The transient response is good on all rails, especially at 12V, where it matters the most.
Transient Response ATX v3.x Tests
The PSU passes all ATX v3.0 transient response tests. However, I don’t want to see below 3.2V at the 3.3V rail. CWT should beef up the respective VRM.
The 12V rail performs pretty well in the ATX v3.x transient response tests.
