Can I have 2xHD7790 in my current system without adding anything extra? I don't know really know anything about setting up Crossfire except that I need the cable thingy which connects the two cards, which I have.

Maybe, your MB supports it but your psu might not be able to cope with both gpu's.
The Chieftec CFT-750-14CS 750W power supply has a maximum wattage output of 750W. This should run most PC builds with ease, but might not be enough for power hungry graphics card setups such as SLI or Crossfire combinations.

As AMD's official page suggests, a minimum of 600W is recommended for crossfire setup, HOWEVER, be sure to check if your PSU has two PCI-E connectors (75W, 6 pins) included; should be okay if it checks out.
