Given this unit’s high max power, the transient response could be better at 12V, and it is also mediocre on the minor rails. This result is due to the insufficient capacity of electrolytic caps on the secondary side. Many electrolytic caps are installed on the modular panel, but have low overall capacity.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 12V and 3.3V rails drop low.
The 12V rail’s performance is far from impressive in these tests, registering huge voltage drops.
