GTX 780 Ti PSU Question

Hi

I just got a killer deal in New Zealand on a used GTX 780 Ti. Got it for $450. I am wondering if it is really necessary to have a 600W Power supply and do you really need 42 amps on the +12 volt rail?

  1. Need full system specs including the make and model of the psu.

    I have an i5 4440, 2 hard drives and my PSU is a Raidmax Cobra 500W.
  3. You'll need a new psu. Raidmax psus are very poor and could fry the new card and everything else in b the system. You could use a good quality 550w psu from Seasonic, xfx, antec, Superflower or evga (gs or g2).

    Ok. Thanks. Do I need to worry about the amps thing?

    Yes the 12v rail amps are important as is the build quality. Looking at pcpartpicker this is the cheapest unit I would use.
