npub1yrlmnr0y2ch5ycn38j2navyduf5q6tqyd0led3p7xhwmzwcrlsaq558gpm (npub1yrl…8gpm) npub12atwfrq4rfv7fqara6gzsgrgj7k8ngewzl5nzs46agwyxzh0e25qxlme5y (npub12at…me5y) It uses the SY8368QNC which is limited to 8A continuous, 16A peak, to supply the 5V rail, but I doubt that the traces on the board are meant for 8A draw; a schematic won't tell you that. Max for any individual pin for the headers they have is typically 1-3A depending on the wires you are using, I think, as well as the thickness and width of the traces in the PCB.

So the biggest unknown is the PCB traces.

But note that it has 6 separate PCM ports for fans, which you really want to use because they have flyback diodes to keep back-EMF from the fans from damaging the board. Inductive loads are not friendly with logic. 😀

So it's not just a question of current capacity, but also of the load characteristics you have in mind.

Sorry, no easy answer here!
