  1. No. That is a low/mid quality PSU. Get a quality 500-550W or more unit. Get a Corsair, Seasonic, Antec, XFX or PC Power unit.
  2. Agreed you need atleast 500 W good PSU.
  3. No it will not take the load of the other card, and when you try to game with it or use high graphic computing power you system will reboot. Choose a good new power efficient PSU with SLI support and a few new things in it. It'll be a good investment....
