ASRock Motherboard (Z390 PHANTOM GAMING-ITX/AC)

Perfect motherboard. I bought directly from the Amazon Warehouse with a condition listed as "Used - Good." The outside box was quite beat up, but the seal on the bottom had not been broken (or perhaps replaced?), and the motherboard inside and all its components were totally completely sealed. Upon close inspection, I saw no scuff marks on the screws nor fingerprints on the motherboard. The screw holes still had the extremely thin, nearly invisible factory plastic that covers the holes until punctured (by a screw).Fantastic value for the money, and I will definitely recommend Used items shipped directly from the Amazon Warehouse. Great Hackintosh motherboard that supports Thunderbolt 3. A Thunderbolt 3 dock allows devices plugged into the dock to be hot swapped natively, and works through macOS Sleep. Flashing the Thunderbolt 3 chip (google "CaseySJ [SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3)") allows native macOS hotswap and Sleep with Thunderbolt 3 devices by enabling full power to the Thunderbolt 3 chip all the time (as opposed to the Windows implementation of full power only after connection to a device is established). The onboard TB3 chip is the same as the one found on the ASRock Z270 Fatal1ty ITX/ac: 2-PCIe lane, half-speed Alpine Ridge JHL6240. Do not expect 40Gbps as this chip supports a maximum throughput of 20Gbps due to its half-speed implementation.Onboard ALC1220 audio provides crystal clear sound. USB 3.0 ports provide at least 450MB/s read and write performance, and the M.2 slot has clocked in at 2.9GB/s read and 1.7GB/s write with a Samsung 960 Pro. Very nice!!3200MHz RAM with 16 CAS latency is thoroughly rock solid with an Intel i9-9900k running at stock frequencies and voltage. Most hardcore benchmark websites show this motherboard can hit 5.0GHz stock with an AIO cooler.Note: The NZXT Kraken X-series AIO's (in my case a NZXT Kraken X53) will only fit in a vertical orientation, with the radiator tubes facing in the North position if the CPU and PCIe slots are south (in other words: Same orientation as the stock picture on Amazon or NewEgg with I/O ports no the left, RAM on the right, and the PCIe slot on the bottom). Due to the heights of the M.2 and rear I/O heatsinks, I'd imagine most AIO's will only fit in this North orientation. The NZXT Kraken X53 and this ASRock Z390 Phantom Gaming ITX mobs work flawlessly in an NCase M1 but may be cramped in something smaller such as a Dancase A4.This is a well designed motherboard with enough I/O to keep you going even through repeated expansions.

I bought this as I have always wanted to do a mini-itx build.The build quality is superb. I mean it's heavy, clean, well thought out and beautiful. The bios is ridiculous, this is my first ASRock board, I have typically stuck with MSI, before that was things like ABIT for those who remember. The reason for this board over the MSI counterpart was for a few reasons.First, this board has 2 M2 slots, where many boards do not. I went with some Crucial P1's here because I think the EVO's are not necessary, and Crucial has had my back since forever, with zero (at-fault) failures. (Once I had a power supply fail that took down the mem sticks, they sent me brand new ones, zero questions). It also has a Thunderbolt 3, and you can kind of see where I am going with this...I decided at the last minute it might be good to make a dual-boot Hackintosh. So one M2 is dedicated as the drive for this. The ASRocks typically end up being pretty issue-free, relatively speaking, when it comes to this, although I am assured the wireless won't work in this case as it is Intel.That all being said, if you basically want everything in a tight little package, this is your mobo. I have seen a few reviews which further support this over others in its class, and everything I have seen indicates this to be so. I have had zero issues with sleep/hibernate/etc, bios flashing was a cinch, the onboard monitoring is nice. The RGB is very notional, and I will warn you, if you get a case which uses a PCIe riser cable, it will cover them (lesson learned but I wasn't so worried about RGB). I have 2 sticks of Crucial Elite 3000 in it, a Seasonic SGX 650, and an i5-8400 (for the price vs performance difference in gaming, I opted to save about $200 for a few frames). Still deciding on a video card, currently running my 1050 in it. This thing is wicked fast. Everything loads so quickly, it's as close to instant as I have seen to date on any device I have owned or used.

I bought this for a FreeBSD based itx server/workstation. I'm happy to report it works great. I had to modify some code in the graphics/drm-fbsd12.0-kmod port to get the graphics working (google asrock uhd phantom freebsd for more info). But now I'm running Gnome Desktop with Blender and Krita while the machine also acts as a server. Great! Bluetooth doesn't work out of the box with FreeBSD 12.0-RELEASE, but I'll work on that. The wifi networking also isn't supported, but the wired Intel gigabit card and sound works awesome out of the box.Hardware wise, I put an 65w low power intel core i9 (BX80684I99900) and two sticks of Kingston HyperX RAM (HX426C16FRK2/32) for 32gb. Air cooling with a Noctua NH-U9S with an extra NF-A9 fan gives me normal temps between 38 - 41C. Under heavier load I've seen up to 59 C. For storage I put a Samsung EVO 970 (MZ-V7S250B/AM) 250GB M.2, and have two spinning disks on SATA for 7Tb total system storage. It all fits very nicely in the amazing Thermaltake Snow case (CA-1B8-00S6WN-01) in a 12.4 x 10.9 x 10.2 box. Power supply is a 650W Thermaktake modular RGB (PS-TPG-0650FPCGUS-R). I'm really happy with this whole setup.

Hands down this is the best Z390 mITX board. This is the best overclocking Z390 mITX board due to VRM and heat sink design so running a hot chip like the i9 9900K is no problem as long as you have the proper cooling. This is the only Z390 mITX board with Thunderbolt 3 but be aware it only runs at half speed at 20Gbps. It can run up to 32GB of DDR4 RAM so if you need 64GB the ASUS ROG Strix Z390-I is a better pick. You get two PCIe M.2 slots and one is on the back and the other on the front with a pretty big heat sink on it and that front M.2 I had the biggest issue with since even with the correct screw driver and not over torquing, one of the screws easily stripped. Now I thought I made a careless error but I went and read some reviews and a handful of people experienced the same thing. Also my first board refused to post and the board had to be exchanged.
