    5.0 out of 5 stars Very nice motherboard
    Reviewed in the United States on December 11, 2024
    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.

    5.0 out of 5 stars Great value and super stable!

    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!

    This is a decent board for the price. If you’re on a budget but want good speeds. Consider getting this one. It’s not the best of the best but it will get you started in pc gaming. Has descent connectivity. Bios options are good but doesn’t have everything. Again good started board for sure

    5.0 out of 5 stars works with AMD Ryzen 5 5500 6-Core perfectly
    Reviewed in the United States on December 7, 2024
    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. (Good Luck)

    5.0 out of 5 stars Top tier

    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

    5.0 out of 5 stars My next Nasa setup
    Reviewed in the United States on November 2, 2024
    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

    4.0 out of 5 stars It's really awesome for everything (except most things)
    Reviewed in the United States on July 20, 2024
    This motherboard was used for my first micro ATX build. It was actually fun to put together and works amazingly. However a couple caveats in most of the build process because of its small size. PCie ports are there but if you have a slightly big graphics card? No they aren't. That means installing wifi internally is very dubious and difficult (I got a tplink USB wifi 6 product). Additionally NO ARGB 3 PIN ON THIS BOARD. Really have no idea why they would only have a RGB header and no argb to be seen. This means most rgb products WILL NOT FUNCTION unless you get an additional hub. Overall I like this board but it will really cost you 115 dollars at least unless you are using Ethernet and no argb...
