Then u can try your card on another computer, if it's fine then u might want to upgrade your PSU with better one... :) 

(did u connect all of the power cable for your card?)

Nothing like Professional one!
Both are good PSU.
750TX is around 20$ cheaper.
Also 750HX has better efficiency.

Get HX if you want modular or otherwise get the TX.
Both are very good PSU and you can always buy Corsair stuff with your eyes closed!!
