Black screen when i install my graphic card

I can't be 100% sure, but that would be a good place to start. You can take the PC to a repair shop or borrow a bigger PSU from one of your friends to test it with your PC before making the purchase.

As I said before, even if the PSU isn't causing the issue, it will probably cause problems in the future.
