Graphics card upgrade

[Luke_58]

Well i have a lenovo h30 (my specs http://prntscr.com/bzg6m1 J1900 CPU and 8GB RAM and a 1TB hard drive.)
I was wondering if i could get a graphics card without upgrading my psu which i think is 240W.
Even so would a 300W min req gpu work in my machine? i was thinking of the nvidia 710 but i wanted some other peoples thoughts.

i have to say its a quad core cpu and i can already run csgo at 60fps however i just want this graphics card more for productivity and watching videos etc.

Any low end card like GT 610,710 HD 5450 etc will not produce any major changes to your productivity and your general usage of your PC. Also your PC has a very low wattage power supply. You can run GT710/610 HD 5450 etc on your current build but the performance gain will be marginal. If you ask me I would recommend you against spending your hard earned cash on buying that GPU.But surely any graphics card will show a better performance than your integrated Intel HD Graphics.
