What I actually found I like best when I was using Ramps, was using a small 6 amp power brick for the electronics, and a separate 10amp brick for the bed. The bed power brick died after 8 months, but it was convenient in that I could leave it at home and still print PLA. They are also cheap and if one power supply failed, I could use the other and still print PLA. No down time. In your case, if you never transport your printer, buy a cheap power brick for the electronics and just use the 20amp for your bed. If you just want a single power supply, look into a 30 amp or convert a PC power supply that has 30 amps on the 12v line (important!).
So to wire it this way should I connect the 20 amp power supply to the 11 amp input on the ramps and the small power supply to the 5amp input on the ramps, or is there something else I have to do?
Do you have pictures of how you have yours system hooked up?
Now the power supply I have has 2 outputs, does this mean 20 amps per output or 20 amp total draw?
Thanks
