You will be able to better figure out the layout peculiarities and slots positioning by looking at the scheme above. However, nothing will certainly be better than the actual mainboard photo:
Of course, a quick professional look at the mainboard will reveal all its major features, however, we would still like to dwell on them to make sure that you don’t miss anything. As usual we would like to begin with the processor. It is powered via an eight-pin ATX12V power supply connector.
The four-phase processor voltage regulator circuitry uses solid-state capacitors. MOSFET transistors are arranged in such a way that a pretty tall heatsink could fit on top of them.
Nvidia chipsets dissipate quite a lot of heat during operation that is why the chipset North Bridge is topped with a large massive heatsink.
Despite the large size, this heatsink got pretty hot, so we have also installed an additional fan to cool it down better.
The chipset South Bridge features a smaller heatsink. Next to it there are a few “lying” IDE connectors, four SATA connectors, two USB pin-connectors that can accommodate four devices, color-coded front panel pin-connectors, Clear CMOS jumper, Power On and Reset buttons.
abit Fatal1ty FP-IN9 SLI mainboard doesn’t need any additional onboard controllers. Its full functionality is provided by the Nvidia nForce 650i SLI chipset. There is a Winbond W83627DHG chip that is responsible for input/output ports, a Marvell 88E1116 chip that provides Gigabit LAN and Realtek ALC888 chip that delivers 8-channel sound.
The mainboard back panel features two PS/2 connectors for keyboard and mouse and a stack of six audio jacks. Between them there is a lonely SPDIF out. The free area on this part of the PCB is supposed to improve the cooling of the MOSFET heatsink that you can clearly see on the photo below.
The list of mainboard rear panel connectors and ports also includes an RJ45 network connector and four USB 2.0 ports – a required minimum for each contemporary mainboard. And as you know abit mainboards have lost their COM and LPT ports long time ago, so we were not surprised to find none of those on abit Fatal1ty FP-IN9 SLI, too.
