For a graphics card to work do you need to plug the cable into the graphics card or can it work if you plug the cable to the pc?

don't know what you mean by "to the PC"... do you mean power cable or video out?

Connect video cable to graphics card itself, not the motherboard, power (PCIe 6+2 pin cable(s)) also to the graphics card.

If you fire up a game, it won't use the graphics card but it will use integrated graphics, if your cpu has it. If you have a cpu with no integrated graphics, you will get no display output.

That depends on the motherboard and CPU. Anything from "it won't work" to "you might be able to make it work but not as well as if you just plugged it into the GPU".

I am confused with your question, not exactly sure what you mean.

 

The card is powered from the PCIe slot on the motherboard and many cards also require aditional power from the power supply and you connect those cables to the card.

 

Any other cables that go into the card are just video outputs like HDMI or DP, etc...

As long as your graphics card doesn't draw more than 65W, it can be powered ONLY by just the motherboard PCIe slot (WITHOUT CABLES):

 

But if you have a powerful GPU (well... higher than 65W) you will need to connect the cables to the GPU like so:

 

And yes, you need to connect ALL the power cables to your MOBO (motherboard):
If not, your CPU, MOBO or RGB will not have power and will not work.
