The transient response is good on the minor rails but mediocre at 12V.
Transient Response ATX v3.0 Tests
The PSU barely meets the ATX v3.0 requirements at 12V with a voltage level of 11.09V in the 200% load test. The 3.3V rail also drops low in the same test.
The 12V rail’s performance is at the bottom of these charts.
