So I recently bought a second graphics card for my PC the other day and when I went to put it in and hook it up I realized that I don't have the 6 pin or 8 pin power cables in my PC since I have a modular power supply and the other cables are at home. I am at college and wont be going home for about a month, so I was wondering if I put the card in now if I could set up crossfire and it would be fine just the card would work as well or will this damage the card and I should just wait.
