You may want something more than 30A or use two power supplies. According to the MakerFarm website the 12" bed draws 20+ Amps at startup; it doesn't say what it draws after start up but I would say probably about 20A. If you figure the rest of your electronics is drawing at most 5A based on the 5A fuse on your RAMPS board. I would use 25A to be safe plus 5A=30Amp+ 30%(good practice)=39A. You would probably be better of with a quality(from what I have read some of the cheaper LED Chinese supplies don't always meet the specs they advertise) 40A supply. You may be better off with two supplies. My 2 cents.
