The 12V rail’s over current protection triggering points are conservatively set, and the same goes for the over-power protection’s triggering points. As I noticed in the other SF series members, the triggering points are higher under hot conditions than cold temperatures, while normally, it should be the other way around. Great Wall has to fix that! Moreover, the OCP triggering points are set sky-high on the minor rails. There is no need for such a high amperage, especially at 3.3V. Furthermore, the OCP triggering points on the minor rails in cold and hot conditions are pretty close.

What do you mean by “Micro Fit” connectors? As I am only seeing mini fit Jr connectors on this psu?
I do apologise, there’s not much information right now but for clarity, the landing page for the updated sfx psus state as such…
sf750 – 2x pice 8 pin cables
sf850 – 3x pice 8 pin cables
sf1000 – 4x pice 8 pin cables
Can you confirm that the new sf750 actually does include 3x pice 8 pin cables?
This is a concern for me.
It has two 6+2 pin cables, as I have in the cable description table, and one 12+2 pin.
I found that there was a typo in the general specs list, fixed it.
