I am not sure what powers supply but please tell me how i can check WITHOUT pullint it apart if possible.
HERE IS THE GRAPHICS CARD

Open up the case, look at the side of the power supply. If it says anything like "Continuous power 550W" or more, you should be fine. Anything below that and it's a no no.

You'd struggle to fit a full sized card in that case though, I've helped people who couldn't get the ACX 2.0 GTX 960 in the X51.

Also...mind the caps please, I think I just lost a few brain cells reading that.

@woody1999 i have looked in the machine, only to find out, im an idiot, i have a power brick power supply, it says input 100-240V, output is 19.5V
i cant find watts

That...isn't good. I did a bit of research and found out that it is only 330W. You'll be able to run a GTX 750Ti, that's about it.

Unfortunately you can't buy a new brick like you can just buy a higher wattage power supply. Looks like you'll have to go with a 750Ti.
