Our take on the ASUS PRIME B550-PLUS AMD B550 Socket AM4 ATX

The ASUS Prime B550-Plus is a full-size ATX motherboard for AMD's AM4 socket, built around the B550 chipset. It pairs a sturdy VRM with two heatsinks and thermal pads, a PCIe 4.0 M.2 slot for fast NVMe drives, and hybrid fan headers for straightforward cooling. It suits DIY builders putting together a Ryzen desktop who want the essentials done well rather than extras like onboard Wi-Fi. Against pricier B550 boards it gives up some connectivity and overclocking headroom, but covers the fundamentals for daily use and gaming builds.

Questions and answers

Does the ASUS Prime B550-Plus support Ryzen 5000 processors?
Yes. B550 boards support 3rd-generation Ryzen and, with a current BIOS, Ryzen 5000 series chips on AM4. Check the BIOS version if you pair it with a newer CPU.
Does it have Wi-Fi?
No. There is no onboard Wi-Fi or Bluetooth, so you need an Ethernet cable or a separate Wi-Fi card or USB adapter.
How many M.2 slots does it have?
It has a PCIe 4.0 M.2 slot that accepts drives up to 22110 length and supports NVMe RAID. A second M.2 slot runs at PCIe 3.0 speeds.
Is it good for overclocking?
It handles mild overclocking and memory tuning through the UEFI, but its power design is more modest than premium B550 or X570 boards, so it suits moderate rather than extreme overclocks.
What form factor is it?
It is a full ATX board, so it needs an ATX or larger case. It will not fit micro-ATX or mini-ITX builds.
Does it support PCIe 4.0 graphics cards?
Yes. The main PCIe x16 slot is CPU-linked and runs at PCIe 4.0 with a compatible Ryzen processor.
