OK, I'm getting confused. If all three yellow and black wires from the Power Supply are hooked together and plugged into the heated bed input, where does the Mosfets and Motors & Logic get their power input from?

you need to provide 12 V to each of the 3 12V inputs on the bard.
I think the manual shows 3 12V wires hooked up to the heated bed but given it's a single rail PSU all that is doing is effectively increasing the gauge of the wire to that line, not a bad thing since you will be pulling 10+A to it. But you still need to run 12V to the other two inputs on the RAMPS board.

So where do I get the other 12v from?
BTW I have a Rambo board.

Any other yellow an black wires coming from the PSU you want, they are all 12V.
Yeah I mean't RAMBO in the previous post.

Thank you.
