RAMPS 1.4 and external mosfets (1 reply)

Hi All,

I am planning on switching to a RAMPS board in the next week or so.
I have a question regarding powering the board when using 2 external mosfets (one for the heat bed and one for the extruder).
If using 2 mosfets how do I power the board? Do I need to connect power to both input blocks (5A and 11A), or just one? If just one, then the 5A or the 11A?

TIA
