    from completed build Skyreach 4 mini brickless build

    Only z390 mini itx board with thunderbolt 3 and has the best VRMs out of any of them. Highly recommended. It doesn't look as fancy as the Asus board, but you definently get more for your money.

    Solid motherboard. Having a 'clear cmos' button was super handy for overclocking. No fancy plastic shrouds and subtle LED at the bottom.

    I'm not familiar with power phases but I haven't noticed anything detrimental to performance based on expectations

    No problems with it. Haven't used overclocking features.

    Great 300-series board for an ITX build.

    • Thunderbolt 3 port on an ITX board is great to have for I/O expansion (since it only has one PCIe slot)
    • Was easy enough for a first time builder/overclocker to get a stable 5.0GHz w/ an i3-8350k
    • Took Corsair LPX Vengeance 3200 XMP profile just fine
    • Builtin WiFi works great on Windows, the included antenna seems decent for 5GHz WiFi
    • No RAM clearance issues with metioned RAM and Noctua NH-D15
    • Only three fan headers, only one of which van variably drive 3-pin fans (but thankfully can). All can drive 4-pin PWM fans well though.
    • Bit pricey compared to other Z300-series boards at the time ($290!)

    Minus a star for the fan header statement, which IMO is important in a "gaming" board meant for overclocking and thus needing to handle some additional cooling. Perhaps that's harsh, it's really my only complaint other than the price.

    I wanted an ITX board with a Thunderbolt port and this one delivered. I don't have a designated plan for it, but I am sure that I would be kicking myself down the line when more thunderbolt port accessories and connections come about. The wireless internet and Bluetooth built in pleasantly surprised me. I haven't had a single issue with not connecting to the internet or losing any of my Bluetooth devices. The BIOS is pretty easy to figure out and looks clean. The layout of the board is intuitive and I had no issues with it whatsoever.

    I simply felt this was the best Z390 Mini ITX board on the market. Vram much?

    What can I say, it’s the only z390 mobo with thunderbolt 3 and I like it’s looks.

    from completed build SFF Build

    It's alright, the BIOS is great, software support in windows is acceptable. Integration with RGB headers and such is meh. It's still one of the best ITX board on the market and great for overclocking. Only issue is some bugs like not being able to control the mobo LEDs when you have another LED controller hooked up.

    Im a newbie so its tough to rate a mobo. I picked this on Optimum Tech's Youtube channel recommendation. I didnt like the fact that only has 3 Fan ports. Other than that and the particularity that I had to put my Kraken X53 with the tubes on top instead of size due to RAM clearance, it seems quite good. Love the simple look aswell.

    It's 5 stars, but with some caveat: little coil whine under certain non intensive CPU tasks. I tried 3 (!) of these, all the same, tried just to choose the most quite one.
