650ti = 110w/12v=9.2a
fx 6300= 95w/12v=7.9a
your mobo should only draw 6a at max load
this gives you a draw of 23.1a on the 12v rail at max load without an overclock
the cx 430 pushes 32a with a variance of .8a so 31.2a
this psu should support the card with your setup but beware that cx series has had issues lately so as you push closer to that 31.2a. just a heads up. i would try it with your current setup and if it runs it fine your good, it is rated for it however if you have issues it may be due to the poor quality of that psu.
