i have the 430W psu that comes in this case. the graphics card runs off of one of the 12V rails correct? if so how do i know which 12v rail the graphics card is on so i can put my hdd and dvd drive on the other one to balance the power?

The 4-pin 12V for the cpu is most likely 12V2 and everything else on 12V1. You don't have the option to choose what rail you want to use so just plug everything in.
