    • works with AMD Ryzen 5 5500 6-Core perfectly

I am a builder who's is building this as a gift so it has to be perfect he lives 1k miles away. I put the AMD Ryzen 5 5500 6-Core its more than enough for him and this board if upgradable down the road.using a sabrent nvm.2 4.0 so boot time is fast. in windows 11 I have no errors at all, all install went perfectly. for a simple build that is stable for non overclocking buy it that said you can play most basic games no problem. also I did flash the bios to the newest BIOS 3611.

    • Great value and super stable!
Style: mATX Size: Prime B450M-A II
Everything was straightforward with this motherboard, easy to navigate BIOS, and very stable with my Ryzen 5 2600. I've got a mild overclock and it holds it's own against some of the newer gear that I have! Definitely a great base for a beginner looking to dip their toes into PC building and gaming!

    • Very nice motherboard
Style: mATX Size: PRIME B550M-A AC
Built an AMD 5 5600G with NVME drive, and 16 gigs of memory. Used the old case, did not have to update the BIOS, and everything worked well. We used an old existing case. The build is very fast and replaeed a old I-5 processor from 2015.

    • Good value motherboard
Style: mATX Size: Prime B450M-A II
Overall this motherboard works pretty well and I have no serious complaints. You do lose 2 of the SATA ports if you choose to use the M2 slot, which I don't like, but I've seen several other boards that have this limitation so I'm sure its some type of chipset limitation. It would have been nice if they could have shifted the x16 slot over one slot so that a 2 slot graphics card doesn't cover one of the PCI-E x1 slots, but I just used a PCI-E extender to move the card from that slot to elsewhere. Also: not sure if this is more an issue with the boardboard or the case I used, but I had to disconnect the USB 3.0 front panel header for cabling purposes, and the fit was so tight between the plastic guide and the cable plug that the whole guide came off with it when I pulled it off. I had to pry them back apart with a screwdriver and then carefully slip the guide back over the pins. No damager and everything works fine, but that was a bit scary. ... show more

    • Totally worth the money
Style: mATX Size: Prime B450M-A II
Review Image by Tristan Tristan
Has ample io and very detailed instructions including how to use bios flashback just in case you have a processor the current bios doesn't support. Doesn't come on latest bios version would recommend you update it when you get it all put together and integrated for more security. Ample compatibility for parts. Make sure all the headers you do use are securely connected as the usb3.0 will not work if you don't push in the connector all the way ... show more

    • My next Nasa setup
Style: mATX Size: Prime B450M-A II
The ASUS Prime B450M-A II Motherboard is like the MVP of budget builds – solid, reliable, and not here to break the bank. Compatible with Ryzen 5000, 3rd, 2nd, and 1st Gen, it’s basically like the party host that invites everyone. Setup is easy, and it’s got all the essentials, so you won’t be digging through your couch cushions for extra ports. Plus, the BIOS is user-friendly, so even if you’re not a tech wizard, you won’t feel like you’re disarming a bomb. It supports up to 128GB of RAM, which is way more than I’ll ever use (but nice to have in case I decide to run NASA simulations from my room). All in all, it’s a solid choice that gets the job done without a lot of drama – and leaves you with some cash left over for, you know, actual games ... show more
