The transient response with normal loads is decent at 12V, and pretty good at 5V. At 3.3V, although the deviation is not that high, still the voltage level drops below 3.2V in the second test, which is something that I don’t like.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests.
The 12V rail’s performance is not competitive in these tests, especially the 200% load one.

Thanks for a review crmaris. Will you be doing a review of PCCooler YS1000?
I think I have them too somewhere 🙂
