Transient Response
Transient response in power supplies refers to how quickly and effectively the PSU stabilizes its output voltage during sudden changes in load demand, such as when a CPU or GPU increases its power draw. It’s measured by the time and voltage deviation during these shifts. A faster, smaller transient response ensures stable power, preventing instability or damage to components.

The transient response is mediocre overall.
Transient Response ATX v3.1 Tests
[Note] For PSUs without a 12+4 pin connector, the maximum applied load for the transient response tests is 150%, rather than 200%.
The PSU passes all ATX v3.1 transient response tests.
The 12V rail’s performance is above average in these tests.

Ares,Do you intend to test the new Redragon PSU RPGS 1000 watts & 1300 Watts Platinum PSUs?
I don’t have any contacts with the brand, sorry.
