Its good for you're money. Im giving it 4 stars bcause I havent installed windows 11 media installation yet, but when I have then i m gonna review again. And also it does boot to bios so thats good to see.Edit1 : This motherboard is great, the pc works. It has earned 5 stars.

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

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

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.
