ASUS Prime B450M-A II AMD AM4 (Ryzen 5000, 3rd/2nd/1st Gen Ryzen Micro ATX Motherboard (128GB DDR4, 4400 O.C.), NVMe, HDMI 2.0b/DVI/D-Sub, USB 3.2 Gen 2, BIOS Flashback, and Aura Sync)

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.

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.

Works

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

Great board. Still using it today on my sons pc

The board is great. I have been gaming hard on it for almost a year and it randomly went out on me recently. I contacted asus and the promptly rma it and in less than a week they are sending me a replacement. It is compatable with various brands of memory. The boot menu and Bios is very easy to navigate and change settings on. I live the look of the board and the led strip that it has on the board itself.. Very good mobo for the price. And excellent customer support. Asus has been my build of choice for years now

die motherboard + cpu does not boot. 4 beeps followed by 5 beeps. I tried this with different rams and difetent cpu's . wast of money

This board is perfect for budget builds and/or first time pc building since the board isn't too complex and simple to work on. Been using board a for several months after building my pc around this board and hasn't caused me problems apart from pcie being gen3 which lowers the full potential of your gpu in terms of fps in games. Ryzen 5000 series CPU is more than capable of running AAA games (Recommend R5 5600 for budget gaming cpu). The BIOS for this motherboard is easy to use and you can just look it up on YouTube on how to use ASUS bios. Would've been great if there was another M.2 nvme slot unless you don't mind using ssd drives. Though you have to buy a wifi/bluetooth card (which are like $35CAD to $50CAD). Other than that, this motherboard is great for starters or someone who needs a budget AM4 mobo.

Quizá le falte una ranura más para m.2 pero fuera de eso no le puedes pedir nada más, para ser la gama económica de asus es de muchisima calidad, solo tengan cuidado si no tienen un gabinete de tamaño considerable ya que esta es algo más grande que las micro atx estándar pero vale por completo la pena, mi próxima mb será una de gama alta de asus sin duda.
