The transient response is very good at 12V and 5V but not that good at 3.3V, where the voltage level drops below 3.2V in both tests.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 3.3V rail drops low in the 200% load test. It only passes because we took into account our equipment tolerances and error margin.
The 12V rail has controlled voltage drops, but other high-end units perform better in this crucial section.

When I saw the fan curve of this PSU from the Cybenetics report, I wasn’t expecting such a poor cooling solution for this PSU! With far better built (and cheaper!) noise-optimized ATX 3.1 PSUs in the market like the Seasonic Prime Noctua TX-1600 or the Cooler Master Silent X Platinum 1300, I really don’t see the point in throwing $699 USD for a PSU that doesn’t even come with fan failure protection.
Such a dissapointing PSU from MSI…
NZXT with price around $369 (it’s around $329 in Indonesia) outclassed MSI MEG A1600T with its price around $700
Really, MSI?
