The card is a bit new for this board but it could well work
It might be possible that the graphic card needs an additional power supply which your computer power supply might, or might not have. This would be a 4 or 6 pin cable.
The only way to find out one hundred percent sure would be to have a look inside your case, and to maybe try it out.
The only part missing is plugging in an extra power cord, (if needed) but if you have one you will see where it goes.
Just do not force a wrong cable in the right place.
I hope this helps

The term AGI 8x was used by ASRock to describe the AGP ports on their old motherboards, at the time there was also a list of AGP graphic cards that were supported by this port. The card you are trying to use would not have been tested for this board as it is far to new, this does not mean however that it will not work, the only way to find out is to try it.
I hope this helps
