How much wattage do I need for my new rig?

That PSU should work well. Nvidia recommends 42 amps TOTAL power, and that PSU having 4x25a 12V rails exceeds that recommendation very well.

That's also a good price for that PSU, and Antec is another good brand.

I guess I'll be getting that PSU then. Thanks for your response
