Gigabyte B550I AORUS PRO AX Motherboard - Supports AMD Ryzen 5000 Series AM4 CPUs, 8 Phases Digital VRM, up to 5300MHz DDR4 (OC), 2xPCIe 3.0 M.2, WiFi 6E, 2.5GbE LAN, USB 3.2 Gen2

first Micro ITX build, actually love this board, makes me want to convert my large ATX builds to ITX now. has everything you need on the board. Wifi works very well once the drivers directly from gigabyte was downloaded. temps are incredibly good surprisingly. Running 3950x and a 5700xt and temps are very good in a small lian li Q58 case. M.2 drives performing incredibly well, dueled up with a 500gb and a 4tb samsung pro m.2.'s. One slot is at the back of the board which is new for me, was looking at the board for 10 minutues wondering 'where on earth is the second slot'. Great product.

This board has a great miniITX layout, which isn't understandable, coming from more budget-oriented boards. The fan adjustment and overall EFI/BIOS menu is what you'd expect from Gigabyte and overall the same as for their other boards.It's worth noting that I had to update the motherboard's firmware/BIOS to a newer version for a Ryzen 5600x. This worked even though the system wouldn't boot with the CPU installed. I could still prepare a USB thumb drive with the update files, plug it into the appriopriate USB port, boot the BIOS, and start Q-Flash with the newer CPU installed.After that update everything went flawlessly. PBO2 is easy enough to activate with this board, the power delivery seems rock solid, it doesn't have issues with a slight undervolt, and remains stable. The built-in Wi-Fi, Ethernet port, and Bluetooth all worked perfectly (your mileage may vary; update the BIOS) and the on-board RGB is a nice and subtle touch. That said, it's not possible to adjust the RGB lightning in the BIOS beyond turning it on or off, and I'm not a fan of installing Gigabyte's software for this sole RGB light in my build.The fan headers are positioned perfectly in opposing spots on the board. One of them needs an adaptor that's included in the box. But, it does feature two ports, which would be unseen on budget boards. Also, the board having two M.2 NVMe ports is welcome, although one is only capable of PCIe 3.0 speeds (which will be fine even for years to come, given that the other does support PCIe 4.0). The front port with PCIe 4.0 also comes with a fiddly but welcome heatsink.Even with an AIO, in a miniITX build I'd be careful with this board to make sure that there's enough airflow running over the board itself. While the temperature of a Ryzen 5xxx processor is easy enough to control, especially with PBO 2, the power delivery parts and the M.2 area do heat up and can impact your CPU's performance. This can be solved with minimal airflow on the board, which is notable since if you're using an AIO you may not think of running another fan that provides some airflow for the board itself.

I bought this MB as it was packed with IO looks really nice and has a nice look. I am running an AMD Ryzen 7 5700g so having 2 HDMI and 1 Displayport means you could run 3 1080p screens which is one of the reasons I bought this. Also, it supports 3200Mhz RAM which is good as my CPU is a g version so having fast RAM is helpful. The issue with the Lan connection as mentioned in some of the other reviews is no longer a problem. The most annoying part of this MB is the BIOS feature called Q Flash it allows the user to update the BIOS just by powering on the MB with nothing installed and inserting a USB drive into the correct port then pushing a button. Sadly I spent many hours trying to get this feature to work and failed. There are lots of threads regarding this issue and I made a point of reading the comments as I thought I must be doing something wrong. Sadly this wasn't the case. I ended up flashing the BIOS by installing an AMD 3400g which worked fine my MB was on firmware F3 (Bought on 16th Dec 2021) It was easy to update the BIOS and once that was done my new 5700g worked fine. Overall I am very happy with the MB but I would warn anyone off buying one if they didn't have access to an older CPU to allow them to upgrade the BIOS. My setup is working great it has 32Gb Ram and has a 1Tb M.2 HD and plenty of cores so that I can run VMware.

I bought this Motherboard on Amazon Warehouse and the board is great but the Quality Control of AW items and their descriptions are not good. This was definitely not 'Like New', but more like used with missing parts. But with the 20% off promo and further reductions due to missing parts, it ended up being really good value than it already is.I have the B450 version of this board also and the B550 board is considerably better spec'ed and has many premium features. Not only does it have onboard LED's as you'd come to expect, but the VRM's are much better and a substantial H/Sink design is found on the B550. Not only this, the rear of the motherboard has a metal frame to sink more heat away.This B550 its board has the I/O shield built into the motherboard which is welcome for installation, and has a zero CPU BIOS flash capability. If the BIOS is trashed/corrupt beyond the 'Reset CMOS' or you need the latest BIOS for say your new CPU then this will be invaluable.Another great additional is that this motherboard supports 2 NVMe SSD drives, one at the rear (Gen3) and another at the top (Gen4). This is additional to the 4 SATA ports available onboard. The only two possible downside are:1) the lack of the new USB 3.2 header for USB-C based cases, but a cheap adapter can be bought to allow a physical connection, but obviously not using the 3.2 functions, only USB 3 functions will be available.2) LED lights control is no longer in the BIOS menu's but via the LED controller apps. I used the Gigiabyte one in Windows and it does the job.The BIOS seems well laid out for a B550. Generally based on enthusiasts web pages this motherboard is in high regard in terms of features, quality, and value for money. This also has a magnetic 'shark fin' style wifi antenna rather the previous screw on mini antennas as used on their B450 kit.All in all a great motherboard for my R9 3900x with my existing 3200MHz 32GB RAM kit for my compute tasks.
