Yes... the Corsair 650TX can have the fan facing up or down into the case. It will work just fine either way. It would be recommended to have facing down in a top mounted case with no top vent / fan (guessing by your current PSU, that might be the case ).
Your PSU choice will be good for any new processor and pretty much any single GPU setup. The PSU I listed, would still work for any new processor update on a lower level single card setup or any on-board graphics setup.
