I bought this based off youtuber ETA Prime's ITX Build using the red Goodisory A01 computer case. Unfortunately for me, the case was unavailable when I went to put this PC together, but with some adjustments, the build went without a hitch. The mini ITX form factor was a very attractive idea. I wanted something for emulation, and for my steam games in my living room (Via Launch Box/Big Box). The motherboard had the most recent bios when I went to boot it up with the AMD 3200G CPU, so luckily, no loaner chip/bios update was needed and everything booted up just fine. The case I went with is actually a bit shorter than the Goodisory A01, and required a low profile CPU fan, which adds to the cost of the build (Plus I bought two 40mm fans to push air on the side of the case). I recommend that you overclock the AMD 3200G asap, as it will get a bit better performance for games like Street Fighter 5, and the newer games out there. This board gave me no problems when overclocking. The included software disc is pretty much garbage, you're better off just installing Windows 10 from a thumb drive, and just updating the GPU drivers via the AMD website. Love this lil board, it's a bit costly, but that's the price you pay for the form factor, packed full of features. As for overall performance, it's very surprising for an APU, I run 1080p out of the box, and get decent frame rates with everything I've thrown at it, usually with medium to high settings. Most emulation works very well. Mostly only issues when running certain games for PS2 emulation. I know this may not be good enough for the hard core audience, but overall I'm very happy with it. Running everything through Big Box is pretty sweet as well. The entire build was about 500 dollars, you can go cheaper with the A01 case, as you can fit the stock CPU cooler, and you don't need to purchase a low profile one.

    • Good board, RGB problems. Go for gigabyte’s aorus b450i if you want RGB to work
4 stars, I sold it because the RGB software is not very good. Buy this board if you want a cheap, budget board that performs better than any a320, a520 boards. I was able to overclock my Ryzen 5 3600 to 4.2 ghz at 1.25 volts stable. Vrms are adequately cool with a good I/o. I have 2 problems with the board. The m.2 slot is located behind the board with no heat sink. The RGB software does not work as intended and I came across many, many problems trying to use the addressable header. Like I said, this is good if you don’t intend to pair RGB accessories with the board. Just get the gigabyte Aorus b450i instead, it’s a lot better when it comes to RGB, plus it has a m.2 heat sink and RGB lighting underneath the board. ... show more

    • Excellent board
I don't know what the negative reviews are all about, but this board is about as good as it gets for the size and price. Mine came ready for Gen 3 Ryzen with no updates required. It currently is sitting in a Corsair mid tower case, overclocking a Ryzen 5 1600x at 3.8 ghz, running 16gb of Ballistix RGB 3200 mghz RAM at 1.4v, and an overclocked Rx 570 to the point that any more and there would be combustion and it has been doing this for almost a year with absolutely zero issues. The BIOS is very simple. There's almost no way you could mess it up. I really don't know what the bad reviews are about. This, for me, is a great board. ... show more

    • Worked for me out of the box for 2700x Ryzen 2nd gen. Great motherboard.
Using this with a Ryzen 7 2700x, this motherboard is working perfectly out of the box with Windows 10 1903 V2. Windows supplied drivers were working perfectly before installing Asrock's latest drivers that also work well. Couldn't ask for more at this price point. The BIOS setup is fantastic, support for 3 fan/pump headers is one more than other similarly price ryzen mini itx boards out there. The design isn't too flashy, the only thing you might worry about as far as matching a case color scheme is the IO shield having a big red sticker on it. I removed it and repainted the IO shield.. I can't complain. It does what it needs to and does it well. ... show more

I got this to install in an Inwin Chopin case. I outfitted it with a Ryzen 5 2400G APU, Noctua NH-L9a cooler, 16GB of Team Dark Pro 3200 C14 (TDPGD416G3200HC14ADC01), and a 1TB Western Digital Blue M.2 SATA drive. The BIOS is fully featured and has all the settings I would expect to find. I haven't had any problems with it so far and am happy. Update 7/12/2020: Just throwing this out there, I have had no problems and it continues to work just fine for me. I'm on the latest bios version for my CPU and everything is good. Update 11/6/2021: Moved to a new chassis, installed the latest bios, swapped the WiFi module to an Intel AX210NGW to get WiFi 6, swapped to a Ryzen 3600x, swapped memory to KLEVV Hynix Chips 32GB (2 x 16GB) DDR4 Bolt X PC4-28800 3600MHz CL18, and added a Vega 64. Everything is still working fine. New photo attached. ... show more

    • Good value; even came with BIOS version 4.60 right out of the box
This board is a good value for anyone who is running a mid-range build. It covers all the essentials, and also comes with great on-board audio, with a full set of audio I/O. Its VRM is relatively weak, but this shouldn't be a problem unless you are running the high-end CPUs. I bought this board on November 5, 2021, and it came with BIOS 4.60 already installed. This was a surprise because version 4.60 came out only a few months ago. So it seems that various earlier complaints about receiving boards with outdated BIOS might no longer be a concern. Interestingly, the sticker on the BIOS chip on the motherboard had version 3.70 originally printed, but this print was covered by a marker, suggesting that the BIOS was factory-updated at some point. ... show more
