I don't see it that way.
We just connected all four red wires, and another red wire (that goes to the battery) together and soldered them, same for the black wires, we will put a 2A fuse in there tomorrow, and just hooked it up to a battery from last year.
I don't see anything that implies a power supply was provided.

Be careful, a switched power supply (as used by a computer) needsa decent load on the main voltage output (which is the +5 V supply) in order to regulate properly. Just putting a few hundred milliamps on the +12 output is inviting catastrophe*.
