This section will guide you through the installation of the motherboard. The topics covered in this section are: Preparing the motherboard Installing the CPU Installing the CPU fan Installing the memory Installing the motherboard Connecting cables and setting switches To reduce the risk of fire, electric shock, and injury always follow basic safety precautions.
Be very careful when handling the CPU. Make sure not to bend or break any pins in the CPU socket. Hold the processor only by the edges and do not touch the bottom of the processor. Use the following procedure to install the CPU onto the motherboard. Unhook the socket lever by pushing down and away from the socket. Lift the load plate. There is a protective socket cover on the load plate to protect the socket when there is no CPU installed. Remove the protective socket cover from the load plate.
There are many different fan types that can be used with this motherboard. Follow the instruction that came with you fan assembly. Be sure that the fan orientation is correct for your chassis type and your fan assembly. Your new motherboard has four 240-pin slots for DDR3 memory. These slots support 256 MB, 512 MB, 1 GB, and 2 GB DDR3. There must be at least one memory bank populated to ensure normal operation. Use the following the recommendations for installing memory.
Use the following procedure to install memory DIMMS. Note that there is only one gap near the center of the DIMM slot. This slot matches the slot on the memory DIMM to ensure the component is installed properly. Unlock a DIMM slot by pressing the module clips outward. Align the memory module to the DIMM slot and insert the module vertically while applying light downward pressure to properly seat the DIMM. The plastic clips at both sides of the DIMM slot automatically lock the DIMM into the connector.
Most computer chassis have a base with mounting studs or spacers to allow the mother board to be secured to the chassis and help to prevent short circuits. If there are stud(s) that do not align with a mounting hole on the motherboard, it is recommended that you remove that stud(s) to prevent the possibility of a short circuit. In most cases, it is recommended to secure the motherboard using a minimum of eight (8) to ten (10) studs.

Make sure you have enough power to cover all the expansion cards you will be installing. To determine what you power requirements are for your specific configuration or a certified power supply vendor, refer to . is the main power supply connector located along the edge of the board next to the DIMM slots. Make sure that the power supply cable and pins are properly aligned with the connector on the motherboard. Firmly plug the power supply cable into the connector and make sure it is secure.
PWR2, the 8-pin ATX 12V power connection, is used to provide power to the CPU. Align the pins to the connector and press firmly until seated. Backpanel connector edge 8 5 4 1 The IDE connector supports Ultra ATA 133/100/66 IDE hard disk drives. Connect the blue connector (the cable end with a single connector) to the motherboard. Connect the black connector (the cable with two closely spaced black and grey connectors) to the Ultra ATA master device. Connect the gray connector to a slave device.
The Serial ATA connector is used to connect a Serial ATA I or Serial ATA II device to the motherboard. These connectors support the thin Serial ATA cables for primary storage devices. The current Serial ATA II interface allows up to 300MB/s data transfer rate. There are ten Serial ATA connectors on the motherboard, The six black connectors (SATA1~SATA6) from south bridge chipset that support RAID 0, RAID 1, RAID 5, RAID 0+1 and JBOD configurations and four connectors (SATA7~SATA10) from JMicron’s JMB362.
The front panel header on this motherboard is used to connect the following four cables. (see Table 2 for pin definitions): PWRLED Attach the front panel power LED cable to these two pins of the header. The Power LED indicates the system’s status. When the system is turned on, the LED is on. When the system is turned off, the LED is off. When the system is in S1, S1, S3, S4 standby, the LED will blink. Some chassis do not have all four cables.
The IEEE 1394a (Firewire) expansion cable bracket is provided in the box but if you do not require the additional external connections, you do not need to install it. Secure the bracket to the rear panel of your chassis. Connect the end of the cable to the IEEE 1394a connector on the motherboard. Table 3.
This motherboard contains six (6) USB 2.0 ports that are exposed on the rear panel of the chassis (Figure 2). The motherboard also contains two 10pin internal header connectors onboard that can be used to connect an optional external bracket containing four (4) USB 2.0 ports. Secure the bracket to the rear panel of your chassis. Connect the two ends of the cables to the USB 2.0 headers on the motherboard. Table 4. USB 2.0 Header Pins Connector USB 2.
The audio connector uses the AC97 standard and provides two kinds of audio output choices: Front Audio and Rear Audio. The front Audio supports retasking function. Table 5.

The motherboard supports a standard 360K, 720K, 1.2M, 1.44m, and a 2.88M floppy disk drive (FDD). The EVGA nForce 790i SLI FTW motherboard contains seven expansion slots, five PCI Express slots and two 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. There are two PCI Express x1 slots that are designed to accommodate less bandwidth-intensive cards, such as a modem or LAN card. The x1 slots provide 250 MB/sec bandwidth.
These onboard buttons include RESET, POWER and Clear CMOS. Easily turn on/off the system, and conveniently clear the CMOS. The motherboard uses the CMOS ROM to store all the set parameters in the bios. The CMOS can be cleared by using the following procedure: Turn off the AC power supply. Press and hold the clear CMOS button for 10 seconds. Turn the AC power supply back on. These onboard buttons turn the system on/off easily and is especially handy for debugging or testing the system.
