Gigabyte A520I AC (AMD Ryzen AM4/Mini-ITX/Direct 6 Phases Digital PWM with 55A DrMOS/Gaming GbE LAN/Intel WiFi+Bluetooth/NVMe PCIe 3.0 x4 M.2/3 Display Interfaces/Q-Flash Plus/Motherboard)

I built a Mini-ITX PC around this Gigabyte A520I AC a few years ago, and I have had zero issues. It works perfectly to this day. It’s a great board for a small form factor build. The Direct 6 Phases Digital PWM is solid, even for powering a mid-range Ryzen CPU. It handled the initial setup like a champ, and the built-in Wi-Fi/AC has always been stable. If you're building a compact AM4 system, this board offers genuine proven Gigabyte quality and reliability. It’s a set-it-and-forget-it component.

After years of using an ATX board for testing items to sell online, I decided to save space. I paired up with an AMD 3200G for the onboard graphics, freeing up the PCIe slot for whatever I need to test. While not the ideal CPU for gaming, fast enough for my needs, and I can add my spare GPU to the carry case and take it on the road if needed. Using a Thermalright AXP90 keeps the CPU cool, there is no fan noise, so I sometime forget it's on. If your case has front panel USB C, you may want to buy the the level MB, to keep the USB 3.2 speed. I haven't found an adapter that supports over 2.0. Other than that, a fair amount of USB ports on the back panel, for basic needs. The WiFi connected without the antenna's attached, that was unexpected. Five months of swapping peripherals for testing, the board passed the durability test, doing the job I need it to do. Most boards are being rebuilt daily.

After a number of system upgrades, I found myself with a DDR4 memory kit, an ITX case and a 5600G without a home. I bought this board and a boot drive to assemble a low power system. Everything I put in was recognized out of the box, Windows install was straightforward and I've had zero issues with it. It's got the a520 chipset, so it's limited to 26 lanes of PCIe gen 3. It doesn't support overclocking and has a fairly basic VRM, so it's not the best choice for gaming. It only has 2 memory slots, one PCIe slot and one M.2 slot so expansion options are limited. If you understand it's limitations and can live within them, it's a great board. For this system I have no need to overclock and the 16 Gb of memory I have in it is all it will ever need. It recognized the XMP memory timings and runs it at the advertised 3600 mHz. Sitting here typing this review while streaming video from a media server it's drawing 31 watts, including the monitors. I can use it for light gaming and I have 6 TB of storage on it backing up some less important stuff. If you're building a gaming system I'd spend the extra money for a more fully featured B550 or X570 board, but for a fast, low power desktop this is an excellent choice.

Works fine, problems with real time clock. Updated to latest bios didnt fixed, if I try to change in bios it it reverts back to wrong time far in future.. So Disabled Debian from using RTC.

Motherboard is great. Super price and well built. Everything locks in tight and secure. Very easy to assemble your computer. Plenty of storage space too built in and for external. No hesitations

So far everything has been great. Mine shipped with the latest bios f15( bios update utility would go any farther). I'm having some weird stuff going on with my nvme ssd. Might be because of the drive I'm using ( crucial p3 1tb pcie x3) but read speeds are low. Not sure why though. Tried getting all drivers loaded and that helped a little. It might be the drive I bought too no idea. Other wise the motherboard is great. The mother board power connector is shifted down from the usual spot so that helped me with my nouvolo steck case. I love having three fan headers too. Downside is the 3rd connector sucks because you need an adapter cable to use it ( it comes with it). Just make sure you don't loose it hahaha. Currently I am running a 5600g, 16gb of ddr4 @3200mhz, and a rtx 3090. Having the GPU and cpu water cooled in a custom loop. Powered it with a Corsair sf750. It's my mini portable rig when I wanna game at a friend's house, host a server, or play in my bedroom( bigger more powerful rig is in the living room). Mini itx boards are the best! No RGB on the board itself to indicate anything for post. But it does have headers for RGB and a speaker. Like some other reviewers had some issues with a different set of ram running at xmp. But that kit might be a dud. It doesn't run anymore in my main rig. It'll be designated to package opening duties.

Looks like I received one of the rejects. How many mother boards come with a CPU fan let alone a fan that has the thermal paste on it in splotches?? The plastic bag the MB was in was shredded and the little bag of screws was gone. Still waiting on the power supply to see if the board works. Paid for a new one and got someone's reject or worse.

It worked with a Ryzen 5600x right out of the box, no BIOS update needed. XMP profile for RAM was 1 click in BIOS setup. Plenty of fan headers and even a few RGB connections if you're in to that. The only cons are the included paperwork is just 1 sheet of paper that just shows an overview of the on board connections, but no labeling of the pin connections; specifically the front panel I/O, which has to be plugged in individually. You will have to search online for the specific model to find the actual 42 page user manual in PDF form to find the breakdown of all the specific pins functionality. No one includes driver media anymore, but you can either download drivers individually from Gigabyte's website, or download their "APP Center" application which will install driver updates for you, as well as some useful (and other not so useful) tools. Pay attention to the setup process with APP Center though, as it will try to, by default, install Norton Antivirus software. You can pick and choose which apps and drivers to install. The on board wifi/bluetooth supposedly supports up to about 450 mbps, but regardless of placement of the antenna, I was only able to get about 100 mbps upload and download speeds both before and after driver updates; my MacBook Pro sitting right next to the PC was able to get 545 mbps up/down. Your mileage may vary however. I haven't tested the on board wired LAN but it's an Intel 1gbps port so it should run at whatever your home internet is capable of. Overall solid board with no issues,
