Review: Great Budget Friendly Motherboard - ASUS Prime B450M-A II – Great Budget-Friendly Motherboard I’ve been using the ASUS Prime B450M-A II in my Ryzen build, and it’s honestly been a really solid experience. I paired it with a Ryzen 5 5600 and 16GB of DDR4-3200 RAM, and everything worked smoothly after a quick BIOS update (which was easy thanks to the BIOS FlashBack feature). **What I like:** * It supports Ryzen 1000 to 5000 series CPUs, which gives you a lot of flexibility whether you're upgrading or building new. * BIOS FlashBack is super helpful — I was able to update the BIOS without even having a CPU installed. * RAM compatibility has been great, and the system feels very stable overall. * It’s a clean, straightforward layout that’s easy to work with, especially for first-time builders. **A few things to keep in mind:** * It only has one M.2 slot, so if you plan on using multiple NVMe drives, just be aware of that. * No PCIe 4.0 support — but for most builds, especially at this price, PCIe 3.0 is more than enough. * There are only a couple of case fan headers, so you might want to use a splitter if you’re running more fans. **Overall:** This board is a great pick for a budget or mid-range AMD build. It’s reliable, easy to set up, and works well with a wide range of Ryzen processors. If you don’t need a bunch of extra features and just want something solid that works, the B450M-A II is a great choice.
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.

A: Yes it is... That's the setup I have in my pc

**Q: Will this work with ryzen 7 3800x?**
