7750 does not require external power, so you should have no problem what so ever to run it

18Amps on the 12V rail?19A is advised. Try 6450 what is the brand of your psu i need more information on that before saying yes or no.

Well i wouldn't risk it but a 7750 is your best bet because a 6670 actually draws more power so my recommendation is it's better to be safe than sorry buy a new power supply first. If not go ahead and do it at your own risk it might work choice is yours of course good luck!
