Well that PSU its not really strong. You have 16A on 12 V rail (you have 2 rails). And 192W on each rail.
I cant find any review about that PSU but i think it will handle it but w/o OC.
That 560 Ti needs 16.7A+ on 12 V rail .
So 200W GPU
And you need 25A for CPU and GPU .
So to end it here i recommend buying a new PSU. Maybe XFX 550W Pro Core for 54$
