PSU question

[misterfatal]

This is going to sound like a dumb question, but. I got a corsair 650TX with no power cable. I have 2 and I'm wondering which one I should use.

18G with 10A 12.5V 1250W And 16G with 13A 12.5V 1625W . Does the difference in AMP of the cable matter? I assume thicker is better.

AMP is very important. Thicker usually means more power. (like and army through a valley against an army through a field). Go with that one.
