AR780 F3 has eleven expansion slots which can support GPU (Graphic Processing Unit) card. Follow these instructions to install expansion cards.
Before installing add-in cards, it‟s helpful to know if they are fully compatible with your motherboard. For this reason, we‟ve provided the diagrams below, showing the slots that may appear on your motherboard.
Simply find the appropriate slot for your add-in card and insert the card firmly. Do not force any add-in cards into any slots if they do not seat in place. It is better to try another slot or return the faulty card rather than damaging both the motherboard and the add-in card.
1. Locate the expansion slot on the motherboard, unscrew the bracket from the slot you want to use and take out the bracket from the slot
2. Install the Intel GPU bracket with 4 screws
3.Insert the card into the slot and secure it with the screws you removed from the bracket
4.Connect the cables between the expansion card and the power distribution board, the connectors you use should match with the slot you add the card with.
