4' x 4' x 8" Router Build

Generally for 4 motors about 50% of total combined capacity will give plenty head room.

I generally go for 50%, then round up to the next transformers size if going for an unregulated supply.

Thanks for the feedback. I’ve asked around in a few places and been told multiple things from 1/3 to 125% of the total current rating which hasn’t made anything any clearer. Let alone the type of power supply - do I go for a switching PSU or just a transformer? AC or DC? I’m still not sure where to go.

This article seems like a good starting point:
