Finally got my 12v stepdown to run the Controller/Raspi off the 12v supply. (Testing on the controller since it's trash, I'll move it to the raspi after 24 hours)

I suppose it's not enough amps to power the USB hub as wel?
Working great for the Pi.
I'm using this one in my next build for the USB hubs since it will run at 5A continuous:

And this one for the Pi just so I don't have to solder:

I have one of the metal top ones for my water pump in my system as a step up 12v to 24v .So they work pretty good.
