  1. Its not going to run 2 GTX 580s, two 560s yes, but 2 580s should really cause you to move up to an 850W unit for safety, especially if you want to OC them at all.
  2. Hello,

    Thanks. I think that when it comes time in a couple of years to get a new card I may upgrade my power supply or just get a better single GPU.

    Thanks for your help!
