The first thing that sticks out about this motherboard is the three PCI Express x16 slots on the board. XFX and NVIDIA are supporting Tri-SLI with this motherboard so three slots makes sense. Note that installing a single graphics card in the second or third slot will bring up a message letting you know that the first PCI Express x16 slot is the one to install a single graphics card.

Four 240-pin DIMM Slots are on the board providing access to up to 8GB of DDR3 1066/1333 memory and support for up to 2000MHz SLI-Ready memory with EPP (Enhanced Performance Protoccol) memory. The fastest available DDR3 memory at the moment is DDR3-1800, but this chipset supports DDR3-2000 memory when it becomes available which should be relatively soon.

SATA drives have replaced IDE drives in the hard drive arena. Today, few if any IDE HDDs are sold with the vast majority of them being SATA. EVGA has put seven SATA ports on their nForce 790i Ultra board, the maximum that the NVIDIA nForce 790i chipset supports. A legacy IDE port and FDD port round out the drive support on the nForce 790i Ultra board.

EVGA has an interesting cooler on the NorthBridge of the nForce 790i Ultra board. The NB is a hot running beast as it reached very high temperatures when not cooled by a fan. The XFX nForce 790i Ultra board has a fan over the NB with a heatpipe leading to the rear heatsink. This should keep this chipset running very cool.

The 24-pin power connector is on the bottom right hand side of the board, meaning cable routing from the PSU is not in the way. The 8-pin power connector is on the top of the board next to the heatsink. This is also a good position as the cable doesn’t interfere with anything. The FP IO on the board is on the far left corner of the board with minimal obstruction a great place as well. The rear IO of the board has the standard PS/2 mouse and keyboard ports, an external SATA port, S/PDIF Out, Coaxial and Digital ports, Firewire port, 6 audio jacks for the onboard audio, and two RJ-45 jacks for the Gigabit LAN. The onboard audio is a Realtek ALC888 solution that is their latest CODEC and offers full support for the High Definition Audio standard.
