The transient response at 12V should be lower in the 20% load test. The deviations on the other rails are low, but the 3.3V rail drops below 3.2V because of its low nominal voltage, which is an easy fix for CWT.
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 180% and 200% load tests.
The 12V rail drops lower in these tests than similar spec offerings. Still, it is way above the lowest limit allowed by the ATX v3.1 spec.
