Fantastic Motherboard
This is another great ASUS Motherboard. Very quick and easy build using this board with the Ryzen CPU. Lots of USB ports, lots of expansion headers and the heatsinks on the control chips are great. I only have a couple of obstacles that had to be overcome using this board. First, there is no speaker or speaker connector on this board. Second, the space between the memory and the CPU is a little tight so be aware of that when you are selecting a CPU cooler. Your CPU cooling fan may end up sitting on top of your memory if your memory has ARGB on it - easy enough to overcome but it slowed an otherwise lightning build down for a while. Lots of support, 3 NvMe slots for solid state storage. This is a lot of bang for the buck. And performance speed? FAST. A great choice for gaming or power computing.

Amazing product
This gaming motherboard exceeded my expectations. Setup was straightforward, and the BIOS is easy to navigate, even for fine-tuning performance. It runs fast and stable, with excellent support for the latest CPUs, GPUs, and memory. The RGB lighting adds a nice touch without being over the top, and the cooling options are well thought out. Every port I need is included, and the build quality feels premium. Perfect choice for a gaming setup—I couldn’t be happier!

Excellent motherboard
This motherboard is easy to setup, provides lots of features, and is great value for money. The reliability is near the top of my list for B650 motherboards.

Finicky with memory needs newest BIOS no diagnostic LEDs small heatsinks but worth it...kind of.
I picked up an Amazon Warehouse open box for some nice savings and as always they are hit or miss. Luckily in regards to shape this is a hit but I can see why it was returned and Amazon marks this as a frequently returned item. This is a 7600x, 32GB (2x16GB) of manually tuned memory and a Samsung 980 Pro 1TB SSD driving a 7900xtx. Unit was used but in great shape with all pack ins. No bent pins and ready to go...kinda. Let's talk about the issues with this board. Memory compatibility and BIOS issues: BIOS on board was 1811 which is 4-5 months old. Using the DDR5 memory in the pic, the unit would not post at all and without LED diagnostic lights appears to be DOA (which it is not) I tried a few other sticks from M-die generic sticks to G.Skill and no post I finally found a circa 2022 M-die DDR5 stick and it posted. Once I was able to post, I updated the BIOS to the newest 2413 BIOS and retried all my sticks and they all worked except the one in the pic which after testing in other boards was DOA. So one of the main problems with this board is memory compatibility which the newest BIOS update seems to address BUT you of course need compatible memory to get it to post so you can update it since it doesn't have BIOS flashback. If the memory isn't compatible, it won't post and can even appear to be DOA without any diagnostic lights...brilliant. No diagnostic LED: For a $200 board, the lack of any type of debug diagnostic LEDs is simply unacceptable. You have no idea what's going on or what is failing. I've seen diagnostic lights on B650 boards costing almost half as much as the Asus board. Weak VRMs: As has been reported, this board has weak VRMs *IF* you're trying to power a top end AM5 CPU. I tested it with a 7600X and a 7950X3D running CB23 multi. The 7600X didn't even break 60c and stayed right around 50-55 for the entire run. The 7950X3D *did* get quite warm hitting into the 80s and 90s. A 7950X will definitely topple it long run. So is it worth it? With all that, there is something about the design and look of this board and its heatsinks I really like especially the chipset heatsink. It kind of just works aesthetically. If you can snag this open box for a good price, have patience and most importantly have access to the right memory then yes. I was lucky enough to have many sets of DDR5 laying around to get it to post and update the BIOS to 2413. Once updated, it works fine. I've been testing and running it for several days now and it has been rock solid. For the retail price of almost $200? Look elsewhere. I like it enough that I picked up both this and an Asus Strix X670E motherboard at the same time and I'll be returning the Strix unopened as this gets the job done at a fraction of the price.

5 stars product with only a few disappointments
Been an Asus MB loyal fan for years and this MB reinforces my positive opinion on Asus. However, I am disappointed that the manual was not included and I had to download and then print the manual online from the Asus webpage. There was only a brief quick start guide included as documentation. I am also disappointed with the BIOS which works but is less user friendly than the previous BIOS. However, the new BIOS included more information. The RAM slots seem a little tight so a little more force was required. When I first turned it on, I am happy to report that everything works without a hiccup using a Ryzen 9600X CPU, samsung m.2 PCIE gen 5 1 TB memory and 32 GB Crucial Pro RAM. I just wished the MB had two M.2 PCIE gen 5 memory slots bc the other M.2 memory uses PCIE gen 4. There is a PCIE gen 5 expansion card slot which is reserved for future AI card. I still recommend Asus MB because my last Asus MB lasted 12 years and is still working.

While I am happy with this board (after i managed to flash the bios) a few little details such as ram and the frequently sold together suggestions from amazon did cause an issue. The board was shipped with the first bios and needed to be updated to the current. This poised an issue with black screens and fear of bricking the board Asus Australia told me to literally F-OFF because even though I purchased the board on Amazon.com.au it had in fact shipped from California and therefore I had no warranty or support rights in breach of ACCC guidelines. Asus have a complete trash customer service team and if you value your consumer rights I would avoid this company and go with MSI or another vendor.

Have to say works like a charm. Likes the black on the steel color plates good nice with each other. Got the with a ryzen 5 7600 with 32gb 6000mhz ram paired with my rtx 3060 ti founder and a MSI MAG A750GL PCIE 5 power supply have to say what a computer. Pop on on first boot but give it time for the motherboard to do her thing. The board fits my Corsair Carbide Series SPEC-DELTA RGB is a tempered glass mid-tower ATX case and was easy to install. Lot of people had problems with wifi and Bluetooth but the fix for that is the drivers is in the armory crate program that comes with the board once into windows it would as to install Armory Crate, install it and once it done u can get the drivers right off that but make sure your Internet connection is wired to get the drivers, once that's installed you should have wifi and Bluetooth working. I would recommend this motherboard
