I am about to make some cables for my computer building project. I've noticed that numerous folks use 16 gauge wire for this. I have some tight narrow spaces to work in and am wondering why some decide on 16 gauge. I added up the amps for my sata connector and don't come close to the amps that would make me use 16 gauge instead of 18 gauge wire. Are there considerations other than amperes that I should be aware of?
