Hi all
Building a corexy and using 2 203w xbox 360 power brick's to power it.
I know about connecting the blue wire to PS_ON and the red wire to VCC but what I want to know is, can I connect both brick's to the same pins? or am I better off just connecting the brick that controls the main electronics/extruder? and maybe putting the hbp supply on a switch?

It should work, when you have a solid GND connection between all the components. Don't daisy chain the GND wires, but specify one point and wire from there ( star configuration )

Thanks for the reply
When you say solid GND connections between all components, do you mean ALL - (GND) from both bricks, -(GND) on hbp, -(GND) hot end, -(GND) Arduino/ramps, -(GND) hot end cooling fan, -(GND) ramps cooling fans all to a single point?

The cooling fan or hotend heater are not critical, but all components, that draw or deliver huge amps should meet at one point
