The transient response is very good at 12V, which matters the most, but the minor rails need improvement, especially at 3.3V, which drops well below 3.2V once the transient load is applied.
Transient Response ATX v3.x Tests
The PSU passes all ATX v3.0 transient response tests. However, the 3.3V rail drops low in the 200% load test.
The 12V rail’s performance is top in these tests.

This seems like a great choice for a PSU, but the underperforming OPP and OCP protections are holding me back from buying it. Have there been any known updates to address this? Since I am not an electrical engineer, I am left wondering what the worst case scenario is for these shortcomings- i.e., damaged pc components, house burns down, etc… Thanks in advance for any update.
