The transient response is good at 12V but needs improvement on the minor rails, especially at 3.3V, where the unit doesn’t pass the second test, since its voltage drops below 3.14V.
Transient Response ATX v3.x Tests
The PSU passes all ATX v3.0 transient response tests, but the 3.3V rail drops low in the 200% load test.
The 12V rail performs well in these tests, dropping to 11.5V at the 200% load test.

–“…and it managed to pass all tests”
Well, I see one red flag on the minor rail. If I’m counting it right, it’s just 0.42% out of 5% tolerance (5.42% under 3.3V)… or I miss something?
please mate would you do a review Zalman Teramax II ATX 3.0 ?
will try to do so ok!
