Got this board for the onboard intel lan, and the 7 phase heatsink. No issues so far.
ASRock Fatal1ty Z370 Gaming-ITX/ac Mini ITX Motherboard Board does what it needs to do and the UEFI BIOS is easy to navigate. Wish it had another Fan Header or two, but with Mini ITX the board space itself limits what all you can have on there. Easy solution is to just run a Y-cable or a Fan Hub. Did a fast Memory OC from 2400 to 2666 on the G.Skill 2400 DDR4 and it seemed to take it just fine. Turned it back off before pushing the Rig out the door though because I didn't have time to validate stability of the OC.
RGB is there if you want it, gone if you don't.
Long/Short Duration Power Limit can only go up to 200W.
M.2 is on the back of the board (not specific to just this motherboard), so airflow is reduced. Can cause throttling or reduced lifespan on PCI-based M.2 drives.
I initially went with the non gaming version of this motherboard, but the sensors and VRMs were somewhat funky, so I decided to return and go with this one since I read in forums that it is the only good ITX board for coffee lake that has good VRMs and overclocking capacity. So far, very pleased with it.
I bought this purely because it's the only mini ITX board with Thunderbolt 3. Still, it does everything else that I want, so I'm very happy with it.
Has all the features I could currently wish for - Thunderbolt 3 is a futureproofing must-have so I was really pleased that here was a Z370 mini itx motherboard that offered it - I understand it supports pretty decent overclocking too though I haven't taken this route just yet. I suppose the only downside is that it could have provided a second M.2 slot on the upper side of the board with a heatsink - like its competitors from Gigabyte & Asus - Also it could have included a 4th fan header like its Z270 predecessor - however it has 6 SATA ports which could serve me well in my Fractal Core 500 case if I ever decide to maximise the full complement of HDD (3) / SSD (3) & 5.25" (1) drive bays.
Beautiful, very nice to work with, one more fan header than its rivals. I like the high spec power chokes, mosfets and capacitors and the high number of phases. Its also got thunderbolt 3 (although it is the lower throughput version) which is pretty impressive at this price.
Not 100% sure on the current market however when I purchased this board it was the only mini ITX board with 7 Phase power delivery. Word on the street was the other boards struggled to get Coffee Lake >5Ghz. I got 5Ghz on the dot @ 1.32v with my 8600k.
I removed one star only because this board doesn't have overly large heatsinks. This is an ITX board designed to be used in a small, enclosed environment with cables potentially blocking airflow from case vents etc. Couple this with watercooling (no airflow over motherboard at all) and I think you might have a recipe for disaster.
