FDD Connector 

The motherboard supports a standard 360K, 720K, 1.2M, 1.44m, and a 2.88M 
floppy disk drive (FDD).  

Expansion Slots 

The XFX nForce 780i SLI motherboard contains six expansion slots, four PCI 
Express slots and two PCI slots. For a full list of PCI Express x16 graphics card 
supported by this motherboard, go to 

www.xfxforce.com

.   

 

 

PCI Slots   

The two PCI slots support many expansion cards such as a LAN card, USB 
card, SCSI card and other cards that comply with PCI specifications. When 
installing a card into the PCI slot, be sure that it is fully seated. Secure the card’s 
metal bracket to the chassis back panel with the screw used to hold the blank 
cover.
