No I would not chance it with a cheap brand. Even a GTX 460 is cutting it close with a cheap brand like that. Look for a good quality unit from Corsair, Seasonic, PC Power and Cooling, Antec, XFX or Silverstone of 500 watts or more for a GTX470. You may even want to go with 550 watts to be sure. A 450w unit from those manufacturers will run a GTX460.
