ASRock Z390M ITX/ac

The ASRock is the only manufacturer to release two mini-ITX motherboards at the launch of the Z390 chipset and the Z390M ITX/ac stands out for quite a number of reasons. First of all the Z390M ITX/ac has dual Gigabit NIC with two LAN ports on the rear panel. Secondly, ASRock has managed to cram six SATA ports onto this board with every port featuring straight angled connectors. Memory support on the Z390M ITX/ac is provided from two RAM slots with a capacity of up to 32 GB and support for up to DDR4-4000.

Design wise the Z390M ITX/ac is very simplistic with what seems like a 6-phase power delivery which looks to be running in a 4+2 configuration. The heatsink doesn't look up to much, but the board does feature a single 8-pin 12 V ATX input which does show that the board is more than capable of running the new 9th generation Intel Core i9-9900K, but perhaps not with an overly aggressive overclock applied. There is no RGB LEDs integrated into the board which says this board is more aimed towards professional users and power users looking to build a high spec small form factor system without too much fluff. The board also features a single PCIe 3.0 full-length slot with ASRock Steel Slot reinforcement and just above is a single PCIe 3.0 x4/SATA M.2 slot.

On the rear panel are a pair of USB 3.1 Gen2 (Type-A and Type-C), four USB 3.0 Type-A and two USB 2.0 ports. Users running processors for the integrated graphics capabilities of the 8th and 9th generation Intel CPUs will be pleased to know the Z390M ITX/ac has dual HDMI outputs along with a single DisplayPort. A combo PS/2 keyboard/mouse port is ever present and the board uses a cheaper Realtek ALC887 HD audio codec which is supplemented by three 3.5 mm audio jacks. Wireless networking is supported through an Intel-based 802.11ac Wi-Fi adapter.

While the ASRock Z390M-ITX/ac shares similar traits as the Z390 Phantom Gaming-ITX/ac, the latter is aimed at gamers while the Z390M-ITX/ac is aimed more towards professional users. This is characterized by the inclusion of dual Intel LAN and a lower quality ALC892 audio codec. The price of the ASRock Z390M-ITX/ac is also another indicator with a recommended retail price of $150 along with the lack of gaming-themed stylings as the board features a basic, yet subtle aesthetic.

    Hi,
    I was wondering whether "MSI MPG Z390M Gaming Edge AC" with processor "Intel i5-9600K" will it work with onboard graphics (Intel® UHD Graphics 630) without a GPU from nvidia/amd?

    "Z390 Motherboard Audio" panel in conclusion is incorrect. For example the MSI Z-390 A PRO has ALC892 but it is not in the list.

    Can you do a more in-depth overclocking guide for this board or is there one? if so may I please have a link to just a basic overclocking guide for this board? I have the board and loved it and I know I can go into the phantom gaming 4 app of course but I would rather do it at the BIOS level and save various profiles for testing but I'm a little new to some of the overclocking stuff but I do have a water cooled system with an 8th gen i5 9706 core so I know I can push it quite a bit :-)

    Just bought an IBuyPower with this MB init.

    Anybody able to hook it up to a home theater receiver?

    7.1 sounds great on the headphones but I gotta take them off every once in while. Can I use the rear audio panel?

    re: Asrock z390 gaming 4
    I know this does have a thunderbolt 5 pin header on the board, is this for thunderbolt 3?
    Will the Asrock Thunderbolt 3 AIC R2.0 pci-e card work with this board?
    or would I be smarter to get the GIGABYTE GC-ALPINE RIDGE (Rev 2.0) Thunderbolt3 Certified PCI-E Expansion card (since I know the z390 is "alpine ridge").

    Also keep in mind that this board has no support for PCIe 4.0 or WIFI 6 802.11 AX in fact, it seems that Gigabyte abandons this board once purchased. If you want PCIe 4.0 to get the most out of the new Gen 4 NVMe M.2 drives or 802.11 AX support you are going to have to spend up and buy the X570 and a new CPU because socket 1151 is finished. A huge disappointment after recently upgrading to an Gigabyte Aorus Pro Wifi only this year...
