Visual inspection

The ASRock Fatal1ty X370 Gaming ITX/AC maintains the format characteristic of ITX motherboards that are part of the Fatal1ty line, using a black-red color scheme and having the dimensions: 170x170mm. The Fatal1ty X370 benefits from all the options of a full fledge X370 chipset equipped motherboard, including one SATA M.2. In addition, this motherboard has no integrated LED illumination however it does offer a 4 Pin connector for LED strips.


The power delivery is a 8 phase type with a 6+2 configuration, the MOSFETs are model SM7341EHKP manufactured by Sinopower while for the power delivery control a single regulator is installed, model ISL95712 PWM manufactured by Intersil. 


The VRM heatsink in the case of the Fatal1ty X370 Gaming ITX/AC model is simple, it features no heatpipe or any other means of heat transfer. In the top left corner of the motherboard, there is the CPU 8-pin power connector. In addition, both the VRM and chipset heatsinks are held in place on the PCB with the help of two metallic screws each.


The motherboard features 3 (three) 4-pin fan connectors, two are in close proximity to the CPU Socket and the last one is on the lower side of the board next to the chipset heatsink.


On the right side, there are the board’s two DIMM slots that support DDR4 type memory with speeds up to 3466+(OC). The motherboard supports a maximum of 32GB of RAM.


Next to the DIMM slots there are the four SATA ports of the motherboard while lower there is an internal USB 3.0 connector.


The motherboard a single metal reinforced PCIe 3.0 x16, the reinforcement helps support the graphics card during shipping and use.


Below the CPU socket and next to the chipset heatsink we have the main chips of the motherboard, the Nuvoton NCT55620 PWM controller alongside the Intel WGI211AT Internet IC Controller.


The audio system has as its center point the Realtek ALC1220 codec while the capacitors used are made by Nichicon and are called Fine Gold.


The motherboard is equipped with one SATA M.2 slot for PCI-E NVMe M.2 SSDs, it is located on the back of the PCB and can support speeds up to 32Gb/s.


On the backside, we have the I/O panel.
The I/O panel is as follows (from left to right):

Final thoughts

The X370 Gaming-ITX/AC is aimed at the gaming market, using the Fatal1ty brand design. The X370 chipset offers the best features for the new AMD AM4 socket and processors available on the market, being also compatible with the new Ryzen 2 CPUs.

The power delivery system will handle even the high-end Ryzen chips available today, the 1700X CPU was handled with ease even at its turbo frequency of 3.9GHz. The 8-phase power delivery also helps in terms of overclocking, the board being capable of getting the 1700X to 4.0GHz at a voltage of 1.41V.

In conclusion, the X370 Gaming-ITX/ac is ASRock’s answer to the constant demand of ITX full-fledged gaming boards with overclocking capabilities. The memory compatibility is extensive and the motherboard can use both low and high frequency DDR4 memory while the AM4 socket combined with the X370 chipset offers great overclocking possibilities.
