An accelerated graphic port (AGP) system uses several control signals to allow an AGP graphic card to enter into negotiation with a motherboard. These control signals can drive the motherboard to provide AGP operating voltage (VCCQ) and providing a first reference voltage for the motherboard according to the AGP operating voltage. On the other hand, the motherboard will provide a second reference voltage to the AGP graphic card according to the determination of whether or not the AGP graphic card is an AGP8X card. Therefore the universal AGP connector of the present invention can enable all kinds of AGP graphic cards to be coupled to the motherboard, and can prompt the motherboard to meet with all the AGP system specifications and support all kinds of AGP graphic cards.
