Help with wiring a power supply

[ahobson1]

I'm planning on building a Galaxy dart board and will more than likely just use a conventional switching power supply rather than hunt for a used one. I'm definitely not an expert with these things and I'm having trouble figuring out how I'd wire this.

Diagram on arcarc:              Conventional Power Supply:
NC -6                                       +12V
RETURN -5                              -5V
RETURN -4                               GND
+5V -3                                     GND
+5V -2                                     +5
+12V -1                                    FG
                                                AC
                                                AC

Aside from GND, +12V and +5V, I don't even know what most of that means! haha
Here are the links for both:

If you are using the same Wires from your arcarc power supply wire everything to the corresponding pin (12v to 12v, 5v to 5v etc...). Run the return wires to the gnd wires
The only thing not speced on the power supply are FG and AC....
FG stands for field ground. that is the ground plug on your wall socket
AC stands for alternating current. That is the other 2 plugs on your wall socket.

Sounds simple enough. Thanks for the help! Im new to this sort of thing, so every bit of advice I get is greatly appreciated!
