Hello all,
I'm a total newbie with electronics, so I apologize if my terminology is off.
My kit came with an ATX PSU and I am trying to connect it to the ramps 1.4. I cannot figure it out through the wiki or tutorial videos. My ramps board does not have a molex connector, but instead has a mosfet terminal. Should I be cutting off the molex connectors from my PSU and sticking them into mosfet slots? Which wires should I be using? When I see the following image:

I get the feeling that I want to cut and use the wires from the 4 pin (2x2) molex connecter because it has 2 black and 2 yellow, and then fasten them into the mosfet labelled 11a/5a, but I don't want to assume this. I also don't know what the L, N and G labels are.
I'm actually getting the sense that a ATX PSU isn't appropriate for this at all. I'm also uncomfortable making these connections. I have access to a 12v 200w power supply: http://www.a2aprinter.com/index.php?route=product/product&path=33&product_id=53. I am attaching a heated bed, and the product description on this 12v power supply mentions that. The heated bed was optional with my kit, should I have gotten the 12V power supply instead of the ATX?
