The transient response is mediocre on all rails except for 5VSB, which doesn’t matter much. At 12V, the most important rail, both tests have high deviations.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 3.3V rail drops below 3.2V in the 200% test.
The 12V rail’s performance is decent in these tests.

The transformer’s visual impact is remarkable, but it is the optical effect compared to the size of the power supply. Seeing 1200w from such a small 850w power supply always makes a certain sense.
