From what i can see,the 5570 has higher power requirement than the 610,400watt with 24 amps on the 12v rail compared to 300watt with 18amps on the 12v.
But the 5570 has a lower MAX TDP of 42watts compared to the 610s 60watts.
Maybe it will work. Maybe it will boot into low power mode due to not having the amperes,im not nearly experienced enough to tell.
