Review: A Great Replacement Board - I updated my son's Cyberpower PC to Windows 11. Everything installed successfully, including all the updates. Then after a restart the display wouldn't come on. That Mobo was an MSI B450 Tomahawk and the LED's said VGA problem. Given the circumstance I couldn't believe it suddenly died. I tried numerous times resetting the CMOS, reseating the graphics card, reseating memory, even checked the power supply, etc. I ordered this ASUS Prime B450M-A II as an economic replacement. It arrived in 2 days and was packaged well. The price dropped 2 days after I ordered. The box has labels Windows 11 ready and Ryzen 5000 Series ready. The board comes with backplate, 2 SATA cables, a M2 screw for mounting, a driver disc and the manual. This ASUS mobo is laid out differently than the MSI. I like it better. The graphics card slot is moved over one space with the M2 slot out in the open. With this Mobo you can use a M2 with a heatsink attached. The MSI M2 slot was directly under a dual-slot graphics card. I like the BIOS flashback feature (located on the back) with this board. The BIOS is laid out well, very intuitive and easy to use. I have built several computers over the years with ASUS my go-to brand. This Mobo is a great full featured B450 motherboard for AM4 series CPU's. The BIOS is upgraded to accept Ryzen 5000 series CPU's. Simply put you're getting a great AM4 motherboard for a great price. Review: Reliable, versatile and easy to install - The ASUS Prime B450M-A II was an excellent choice for my PC. Installation was straightforward, and its compatibility with various generations of Ryzen processors gives me plenty of flexibility for future upgrades. It supports up to 128GB of DDR4 memory and allows for stable overclocking, which improves performance without any hassle. It also features modern ports like USB 3.2, NVMe, and HDMI 2.0b, making it very complete for its Micro ATX size. BIOS Flashback and Aura Sync are very useful extras that make setup and customization easier. All in all, a reliable and well-balanced motherboard. ## Features - AMD AM4 Socket : Compatible to Ryzen 5000, 3rd/2nd/1st Gen AMD Ryzen CPUs.Operating System : Windows 10 64-bit.

That's the setup I have in my pc **Q: Will this work with ryzen 7 3800x?** A: It will work, but this is a low budget motherboard with basic VRM, so kind of will limit what you can do with a high end CPU.
