Good budget OC board

Pros: Comprehensive and intuitive BIOS
Lots of features for the price.
Capable of a decent I7 overclock if you spend the time to find the lowest stable voltage settings.
Built in AC wireless.

Cons: BIOS caps turbo boost to 130w/140w
Default voltage settings are rather high, especially given the limited VRM capacity.

Overall Review: Good ITX board in general, great at the price point.

It can handle a mild overclock on an i7-9700k. The BIOS only allows up to 140w Turbo Short Max Power, and 130w Long Max Power. It's capable of stable overclocks, but will throttle often with i7 CPUs as it bumps into the wattage limit. This is exacerbated by the default voltage profiles, which are overly aggressive. Lower TDP i3 and i5 chips would probably work more eaily within the VRM limits.

With my specific samples, it's managing 5.0 on 4 cores and 4.8 all-core on non-AVX loads, and 4.7 all-core AVX without throttling. Higher values were stable, but throttle fairly frequently due to the wattage caps.

My favorite go-to board

Pros: Small but powerful
Two Ehernet ports
Built-in ac wirelless
Highly expandable
Excellent BIOS
No electrolytic capacitors except in the audio amplifier.
I believe motherboard reliability increases as they become compacter and computer chip integration becomes more dense which decreases the number of parts and solder junctions. I throttled the 120mm case fan way down which increases fan longevity. The case remains cool with the low power 65W CPU.

Cons: None if your goal is to build a small put powerful computer.

Overall Review: I'm a system builder who formerly used only mATX boards but later realized that this Mini-ITX board provided all the power I needed. I've built about 10 computers using the Asrock Mini-ITX format (Z270, Z370, Z390) and couldn't be happier:

Great for the price!

Pros: The all black design has been much appreciated and thus far I haven't experienced any issues with the drivers, heat dissipation, or ports not working.

Cons: None

Overall Review: ITX pc's can be a hassle to build but this MOBO made it a little easier.

Impressive Features inside tiny board

Pros: -Can handle lots of mid-grade and top tier CPUs
-CPU socket is very well placed and oriented
-I/O hardware is pleasantly minimalist without sacrificing versatility. ESD/bump guards are very well designed
-Interesting multi-use m.2 slot. Very well placed despite lack of room once a PCIe card is installed. Easy enough to access even if you have a full size or larger graphics card
-Reinforced PCIe slot is a big plus (old ASUS Z97 had one slot go bad from graphics card weight)
-Nice looking and functional heat sinks installed on most heat generating areas of the board
-UEFI setup/maintenance is quite user friendly

Cons: -Manual leaves a lot to be desired in regards to helping builder hookup various case cables
-Connections for SATA drives and other internal components are awkwardly spread out, some are hard to reach even with minimal obstructions
-WiFi module seems to pick up interference when more than one USB3 device is connected. Easiest solution was to buy antenna extension

Overall Review: -Possible incompatibility issues when combining use of SSD and HDD drives. Have been experiencing occasional system freeze ups if one of my HDDs goes idle and is called back online by Windows after a few minutes. Can't say it's been a problem, not a single blue screen but it is very aggravating.

• Clear the CMOS.
• Reseat the CPU and heatsink fan.
• Test with single memory module (un-buffered).
• Test with onboard video.
• Connect the monitor.
• Plug the 24 + 8 or 4 pins ATX power.
• Connect the chassis power switch to mainboard.
• Turn on the power to check if its post.

Pretty good for the $$

Pros: Well-rounded Mini-ITX Z390 m/b
gotta like black
boots macOS 10.14.3 (with a DSDT patch to fix an AsRock-specific BIOS issue)
two ethernet ports if that is your thing
cheap!

Cons: No optical audio out and cheaper audio chip (but not a big deal for me since I prefer USB sound interface instead)
Onboard BT4 not BT5
Only 1 m.2 slot for SSDs

Overall Review: Unlike with my AsRock Z170 board that had some BIOS display issues (boot picker had garbage characters instead of ASCII) no issues encountered installing Windows 10 & macos 10.14 (latter requires a certain AsRock-specific DSDT patch in Clover's config.plist)

This review for ASRock review rebate program.

Pros: This motherboard has amazing features: native support for video - up to 3 monitors with 2 HDMI ports and 1 Display port; USB 3.1 1X type C and 5X Type A; Ultra M.2 port that accommodates 4 different lengths of M.2 boards.; native dual mode Wi-Fi; 8th and 9th Generation Intel CPU support; All this and more in an ITX size. I love it.

Cons: None

Overall Review: I needed a small computer - SFF form factor; this is just perfect for my needs. I am not a gamer, but this motherboard can accommodate a video card should you desire one. This board is just perfect for my requirements. Another great product competitively priced from ASRock.

Worked great out of the box, no problems!

Pros: This board looks great and installed easily into my Node 202 case. It's been running for about a week now with no problems. BIOS wasn't hard to navigate and enable RAM XMP profile. I like the black coated board.

Cons: None that I've found so far. I'm not a huge fan of the Windows-based tuning utility, but it's not something I would normally use anyway.

Overall Review: This review for ASRock review rebate program.
