    • Good value
Style: ATX Size: PRIME B550-PLUS(Pack of 1)
I paired this mobo with a 5600x, and since it came with an updated bios it rain the cpu without issue, though there is a more recent bios. I did, however, have issues getting it to work. It would turn on, but nothing would display on screen and the green boot light stayed on. Long story short, replacing the cmos battery seems to have done the trick. This issue has not returned since the new battery. Some of the plastic looks kind of cheap, but it's not a big deal and only noticeable when installing stuff. Otherwise it looks quite nice in the case. For anyone who doesn't like the "audio led", it can be turned off or set to static in the bios. Software wise, Armoury Crate sucks. I recommend going into bios and turning off the automatic install. AI Suite 3 is decent, though everything can be adjusted in the bios/uefi. If you need something to control rgbs, openrgb is a good option. Amd has more recent chipset drivers than what's available on Asus's site, so I recommend getting them from there. All in all, I'm pleased with this motherboard and it was a good price. Everything works and it has plenty of options, plus it's windows 11 ready, which is nice. ... show more

    • Solid and stable
Style: ATX Size: PRIME B550-PLUS(Pack of 1)
Have built three systems with this family of boards (ATX and MATX) and all three systems are rock solid stable. Not overclocking on either system, so can't speak to that, but great midrange boards with the ability to use DOCPS for "overclocking". One strange thing I have seen on the MATX board is that you have to use the DVD that comes with the board to install the drivers for Bluetooth and WiFi! The downloaded drivers, from the ASUS site, do not initiate and Windows doesn't recognize the chips. I recommend you use a DVD drive and the open device manager, select the unknown network adapter, select update drivers and point at at the DVD. Don't know about the ATX boards as neither had WiFi onboard. ... show more

    • Good board but some learning curve
Style: ATX Size: PRIME B550-PLUS(Pack of 1)
I had previously built a gaming rig with similar hardware, but the MSI B550+, still Rizen 5600 Vermeer and Ripjay V's, that build went smoother but I tried some new things with this board. First, after building I got error beeps, 1 long and 3 short, which normally means memory (multiple seating, unseating, swapping with the other build). Turns out it wasn't memory but my video card wasn't seated well. Tried again and all good. Next comes my change, old build had a sata ssd drive, for this I got a Samsung M.2 drive for the OS. Install went fine but like others have seen, the bottom two sata port would not work. Turns out I used the lower M.2 slot, this shares those ports so if you install a drive on the lower (m.2.2) slot you lose 2 sata ports. I moved the drive to the M.2.1 port (next to the CPU, above the video card slot) and those two Sata ports came back. Something to look into if you have Sata issues (I have multiple drives on this machine so I need all Sata ports) Last nuance (so far), Windows was taking FOREVER to shut down. Restarts were ok, but you click shutdown, it would do nothing for a minute, then swirly circle with Shutting down, then blank but lights still on, overall 3-4 minutes. Tried multiple installs, disable hibernate, everything. Turns out, you need to do all Windows updates and then go into the optional updates and update all drivers (I suppose you could use the disks as well). Now that is smooth again too. So, great speed, lots of Sata, USB (2.0 and 3.2), and if i want to add a bunch of RGB I have those to play with. Will be playing with this for weeks and will update if I run across anything else. ... show more

    • Saved me.
Style: ATX Size: PRIME B550-PLUS(Pack of 1)
Easy install. DID NOT require BIOS update for use with 5600X Coupled with 32 GB RAM, 5600X, 1080 Gfx card (used w/warranty direct from AMD) + my own SSD and Power Supply from my failed PC ... For less than $500 I got my gaming computer back together in about an hour from delivery-to-first boot. It's been since B4 COVID since we have had money to build new. This build gave us a very affordable solution that allowed us to access our critical info and put me back into games the require high-end cards like 3070+ playing at fair-to-good FPS. (ie, Ark Survival Ascended - ok performance, Fallout 4 and 76 - OUSTANDING performance, World of Warcraft The War Within, which just came out, - OUTSTANDING performance). Hope this helps you get back in the game quickly. ... show more

So for my budget build this was a must have ! Already came with the chipset for my cpu choice and was windows 11 ready so this was a no brainer. Out of the box she performed amazing and after messing with her bios settings and installing all the latest drivers she was even more amazing ! Just the speed and efficiency is mind blowing. And with the pci expansions you can pop a fast operating Wi-Fi card in which saves you money starting out so you can spend it elsewhere like for the gpu or psu. Anyway this mobo met all my needs for a comfortable price so I’m glad I picked it up ! I would absolutely recommend this mobo if you’re on a budget and just starting out to building like I am ... show more

I use this B550 as a test bench for troubleshooting my family and friends' computers. Since the am4 platform has been an easy thing to recommend for the past forever now it sees a lot of connects and disconnects. All the connections are still solid. Only the CPU has slipped out once from pulling a cooler off but that happens to every am4 motherboard eventually. ... show more
