As for the advantages, I have to point out secure retention of the chipset cooling system that is fastened with metal screws instead of traditional plastic clips that could be not very reliable.
Lower part of the mainboard PCB carries two PCI Express 2.0 x16 slots, one PCI Express x1 slot, three PCI slots, a POST-code indicator, Power On, Reset and Clear CMOS buttons, and an additional IEEE1394 controller (Texas Instruments TSB43AB22A). As you may see, two stacks of Serial ATA ports (four total) and a FDD connector are positioned horizontally for convenient use with long-PCB graphics cards.
The mainboard rear panel has PS/2 keyboard and mouse connectors, IEEE1394 port, an optical S/PDIF, six audio-jacks, network RJ45 port and six USB 2.0 ports.
The manual for EVGA nForce 750i SLI FTW mainboard doesn’t have the traditional PCB layout scheme, but the illustration they offer instead allows figuring out the location of all major components:
You can connect six fans to this mainboard, which is great. Only the locations of these connectors could have been better. If your system case has a fan on the back panel, it’d better have a cable long enough to reach the connectors on the front or very right sides of the mainboard PCB.
In conclusion, let’s take a look at the technical specifications of EVGA nForce 750i SLI FTW mainboard:
