It's good board, and it worked well. My only wish is that it would ship with the latest BIOS already installed. if it does not have the latest BIOS installed, you may have to flash it without a CPU, or use an older CPU temporarily, to get the BIOS updated, to support the latest compatible CPUs.

This board is the best bang for your dollar. WIFI is amazing and the Bluetooth works great for my ear buds and Xbox controller. The only thing I will say I do not like that there is no RGB on the board and nothing lights up but that is plainly cosmetic and not functional. This was my first PC build and the BIOS was easy and simple and everything worked as it should have out of the box.

Works perfectly!!! Finally!I bought a refurbished board (model Asus Prime B550M-A Wifi) from another vendor and boy was it a nightmare. First, it's "renewed like new," condition didn't even include original accessories. The wifi antenna was not original but a generic version (2sticks) and pulled only 21mBps. This is a 300Mbps internet connection so I expected more. Well, this Amazon "used" is so much better at 50Mbps, simply because the antenna is the original part. I was even ready to let this pass, since I intend to use a cable, until the board had other issues, it would not let me into the bios. There was no splash screen with prompt to hit the "del" button. I tried every way of getting into the bios through, windows reset, windows restart/recover, resetting the CMOS, every which way possible but it would not let me. So I returned it for a replacement. It never arrived. They canceled it and I didn't even know. So between all the delays, all the other components' return windows had closed.Amazon to the rescue!I bought the same board but through Amazon warehouse. It is perfect. As in the description, the box is beaten up that's about it. The board and all the accessories are original parts and work great. The only thing is it is only a 30-day return window while the other was 90 days. So I'll test this board thoroughly in the given time and make sure all is well.I have bought many refurbished or "used" items from Amazon warehouse and have yet to be disappointed. Of course, I think there were a few times the product was not satisfactory and Amazon took it back without a hassle.As for the mobo, look, I'm not a techie and I hear the AMD APU Ryzen 5600g chip is a bear to O.C. so I'm leaving it alone. The nice thing is with this board I can connect it to 3 monitors and since I'm going to be day-trading on it, it works out great. I've also found that if I add another discreet GPU with more video ports all will work without issue to have even more monitors.All in all, after nearly 2 months of delays the system finally came together.Thanks Amazon!

This is my second Asus board build (previous was an AM3+ platform). The board itself is basic but good.Pros: it has WiFi (requirement for me). It's an Asus board, so it works with the AI Suite and the newer Armory thing. But basically the reason I choose Asus is the software, the AI Suite.Fan Xpert tuned my fans automatically, allowed me to label each one and automatically set the low end RPM correctly. Every fan needs a slightly different curve but together they are quiet and cool.Windows 10 detected the board, then auto downloaded and installed the armory thing, which you can use to download AI Suite and other apps.There's 4 fan headers. Which is about right. The BIOS is still good.The onboard lighting is subdued (and configurable). I can sleep without the board lighting up the room.Cons : it's a no frills board. There's no power button on the board (which is a frustrating point for testing). There's an outdated IO shield that miraculously worked with my chosen case (to me it's a crapshoot).You can buy better featured boards for less but I think the software that ties it all together is worth it for me.So in summary it's a nice board if you can stand that it doesn't have every feature and doesn't have GAMER written all over it in neon lights.But basically a low end board with WiFi added.
