Connectique et I/O
In total, ASRock equipped the Z370M-ITX/ac motherboard with six SATA 6Gbps connectors, which have all been natively wired to the PCH. Furthermore, there is one M.2 x4 Gen 3 slot. With this motherboard you also get one black PCIe x16 Gen 3.0 slot. Due to size and the price of the motherboard, there are no practical onboard power- and reset-buttons and there is also no debug LED.
There is a total of three fan headers on the Z370M-ITX/ac which is enough, to provide a well equipped ATX system with fresh air. The headers have been located close to the CPU as well as spread over the board. Other than that it's a good thing that all of them feature four pins, which allows for rpm regulation in BIOS as well as under Windows. Furthermore there is a plethora of additional headers you find listed below:
