The transient response is mediocre at 12V because of the huge voltage drop in the 20% load test. The other rails perform well here.
Transient Response ATX v3.0 Tests
The PSU meets the ATX v3.0 requirements. It would be nice to see above 3.2V at the 3.3V rail, though at the 200% transient load test.
The 12V rail performs decently in the ATX v3.0 tests. The only other 650W ATX v3.0 unit for which I have data has a notably higher voltage level, though, at 12V.
