  1. Of course, if it were the other way around, then that would be a problem. Just make sure your 12v rail/s aren't maxed out.

    Ok, its safe to assume that 90% of that will be in 12V, so get something 60A on the 12V rail or higher. Usually you will never hit the max, but you always want overhead. Graphics cards are always overrated as to not let people have bad powersupplies run them, but if you can get 60+A on 12V, you should be good to go!
