    • Easy install and tons of bells and whistles
Style: ATX Size: B550-Plus AC|M.2x2|D4|WiFi5
Plenty of PCI-E ports, all appear to be x16. Works with argb lights and was easy to install in my case. Parts were equally easy to install with plenty of space for everything. The m.2 works, the sata works, the extra usb stuff works. Its a good board

    • Solid Performance for My Home Arcade Build
Style: ATX Size: B550-Plus AC|M.2x2|D4|WiFi5
I used the ASUS Prime B550-PLUS AC-HES AMD AM4 motherboard for my home arcade build, and it’s been a fantastic choice. The setup was smooth and the board offers great compatibility with my components. The B550 chipset provides solid performance, and the board handles everything from light gaming to heavy multitasking with ease. I was particularly impressed with the built-in Wi-Fi and Bluetooth, which made setting up my arcade PC wireless and hassle-free. The board’s design is clean and compact, and the onboard audio is crisp, which is perfect for my arcade cabinet’s sound system. Overall, this motherboard offers incredible value for the price. It’s stable, reliable, and more than capable of supporting the needs of a home arcade system. Highly recommend for anyone looking to build or upgrade their setup! ... show more

    • Great Mobo, though it took 2 to get a working one
Style: ATX Size: B550-Plus AC|M.2x2|D4|WiFi5
I chose this board for specific features, namely the 6 SATA ports. The first mobo would not work. It powered up, but there was no video ( using a discrete video card). After extensive troubleshooting, I had the board replaced by Amazon (thankfully an easy process). The second board has worked well. There are plenty of slots, and components are not cramped together. A good board for a budget build. ... show more

Review Image by Bobby B
Great for a budget build, paired it with a Ryzen 5 5600GT, 16 GB Corsair Vengence DDR 4 3200, Crucial P3 Plus 1TB PCIe 4.0 3D NAND NVMe M.2 SSD, Corsair 650 W power supply, and an old case I had sitting around that had a DVD burner in it, total cost under very low. Not as fast as my Ryzen 7 7700X machine but plenty fast for everyone except an avid gamer. First thing I ran into was the back plate that covers the USB and other ports was wrong, so couldn't use the USB flash port (already had the board installed when I noticed this, didn't feel like taking it out again so had to update the bios using Windows 10, Windows 11 didn't recognize the CPU, their flash utility didn't work so loaded Windows 10 first, used it to update the BIOS in Windows, then upgraded to Windows 11. Maybe not the best way to do it but it worked for me (having a Microsoft account was able to install Windows 10 then upgrading to Windows 11 with no problem.) With the stock wraith cooler temp sits at 40 degrees Celsius, well within specs. I've built several computers using AMD processors and Asus motherboards, never had a problem with either one. After you update the BIOS use the Armoury Crate software from AMD to update all the drivers including the wireless drivers and all will go smooth. Really the only con is needing to update the BIOS but don't really consider it a con. ... show more

Style: ATX Size: B550-Plus AC|M.2x2|D4|WiFi5
It's a really good motherboard, I do not need to do any particular overclocking or anything so the PRIME line for a regular basis, handles my Ryzen 7 5700G just perfectly! I absolutely recommend it for those who require a budget-friendly build.
