Frequently Asked Questions
B550 supports PCIe 4.0, which means faster NVMe drives and better GPU bandwidth. B450 is stuck on PCIe 3.0. For budget builds with older Ryzen CPUs, B450 does the job. But if you're planning to upgrade to Ryzen 5000 series or want faster storage, B550 is worth the extra £40-50.
The B450 boards (Prime B450M-K II and Prime B450-Plus) need a BIOS update to run Ryzen 5000 chips, and even then, you'll miss out on features. The B550M-Plus WiFi II supports them natively and is a better choice if you're running a 5600X or similar. Just check ASUS's CPU support list before buying.
The B550M-Plus WiFi II includes WiFi 6, which is proper decent value. Separate WiFi adapters cost £20-40 anyway, and motherboard WiFi is cleaner with better antenna placement. If you're on Ethernet, save the cash and get the non-WiFi version.
Most people use one, maybe two. Budget boards typically offer 2x M.2 slots, which is plenty for a boot drive and game storage. Unless you're running a media server or serious content creation rig, two M.2 slots will cover you. Don't overpay for extra slots you won't use.
Yes, easily. Under £150 gets you solid AM4 or AM5 boards with WiFi 6, 2.5Gb LAN and dual M.2 slots. You won't get the premium VRM heatsinks or PCIe 5.0 GPU lanes of £250 boards, but for a mid-range gaming or work build, boards in this bracket cover everything most people need.
