The transient response is mediocre at 12V, primarily because of the high voltage drop with a 20% starting load. It is good on the minor rails.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests and the 3.3V rail manages to keep its level above 3.2V.
The 12V rail performs well in these tests since the transient load is applied while the PSU is already in a high-load operation.

I noticed that the test results, especially the fan control, differ between this review and the report 24PS2426A for same model. Did the review test a new revision that is not yet on the market?
Seems, I found the relevant report – 23PS2308A. This appears to be an earlier revision of the power supply.
I can use a different test sample than the one listed on Cyben
