I am in the middle of installing my Car PC ... I have been using a regular power supply to setup everything. Now that I am installing it in my car my main question regaurding the M2-ATX is about extending the three power wires.

I noticed that all three power wires are rated at 18 gauge. I was wondering if that will be suitable for the power load. What have the rest of you done with the power wires?

I have attached a rough drawing of my setup below (Note that I am using a 4 gauge power wire with 150A fuse).
