Luke, welcome to the forums.  If both of your 980 TI's are EVGA, then yes.  I don't see part numbers but I'm guessing they have different coolers, correct?  
 
In regards to power you are also fine there, even taking into consideration the other components.  If you start adding pumps and dozens of fans and mechanical storage we may need to do the math.  A single 980TI is rated at 250 watts so a second would double that.  Still plenty of power for your other parts.
