Thing is, I have heard a lot that people use super powerful PSU and fry their system. I choose a 750W PSU and my build only needs 448W. My plan is to crossfire in the future so I wanted to buy a good PSU now. If I were to crossfire my current card I would require 698W. Thanks everyone!

you can't fry it due to too good of a psu. the psu you selected is pretty good but I would personally get something a little better for crossfire 7970s and an overclocked CPU

No its fine think of a power supply in your computer as the engine in your car. A bigger engine won't harm your system it may be more then you need but it will allow you to carry more, and get up to speed faster.

It's a little more than you need , but having extra horsepower can't hurt.
