Our take on the Asus Prime B550-PLUS Desktop Motherboard

The Asus Prime B550-PLUS is an ATX motherboard for AMD's AM4 socket, built around the B550 chipset. It pairs a 3rd Gen Ryzen CPU with PCIe 4.0 for the graphics card and one M.2 slot, and adds a second M.2 slot, 1 Gb Ethernet, USB 3.2 Gen 2 Type-A and Type-C, DisplayPort and HDMI, and an addressable Gen 2 RGB header with Aura Sync. VRM and chipset heatsinks plus Fan Xpert 4 cover cooling and fan control. It suits DIY builders who want modern connectivity and tuning tools without the extras of a premium board; rivals at this tier often match the layout but add Wi-Fi or stronger power stages, while the Prime leans on Asus firmware and software.

What reviewers say

Owners of the Prime B550-PLUS generally describe a solid, no-frills board that installs easily and runs stable with mid-range Ryzen chips. Praise centers on the dual M.2 slots, PCIe 4.0 and the clean UEFI, while criticism tends to land on the basic networking and the lack of built-in wireless.

What people mention
  • ConnectivityMixedOwners like the USB-C and dual M.2 but miss built-in Wi-Fi and 2.5 Gb Ethernet.
  • PCIe 4.0PraisedBuilders value PCIe 4.0 on the main slot and one M.2 for fast graphics and storage.
  • BIOSPraisedThe UEFI is described as clear and easy to navigate for tuning and fan setup.
  • Power deliveryMixedSome owners say the VRM is fine for mid-range chips but not ideal for high-core Ryzen models.
  • CoolingPraisedVRM and chipset heatsinks keep temperatures in check in normal builds.
  • RGBPraisedThe addressable Gen 2 header and Aura Sync make lighting setup straightforward.

About the Asus Prime B550-PLUS Desktop Motherboard

The ASUS Prime B550-PLUS is an ATX desktop motherboard with an AMD B550 chipset and an AM4 socket. It is ready for 3rd Gen AMD Ryzen processors. It has dual M.2 slots, PCIe 4.0, 1 Gb Ethernet, DisplayPort and HDMI outputs, SATA 6 Gbps, and USB 3.2 Gen 2 Type-A and Type-C.

Two VRM heatsinks with thermal pads help move heat away from the MOSFETs and chokes. A PCH heatsink and hybrid fan headers, along with Fan Xpert 4, handle cooling. The PCIe 4.0 M.2 slot supports drives up to 22110 and NVMe SSD RAID, with storage speeds up to 64 Gbps.

An onboard addressable Gen 2 header connects RGB LED strips, and it syncs with Aura Sync-capable hardware. The audio design uses shielding to separate the analog and digital signal domains. It also has a separate layer for the left and right tracks to limit crosstalk, and it uses Japanese capacitors.

Questions and answers

Does the Prime B550-PLUS support PCIe 4.0?
Yes. With a compatible 3rd Gen Ryzen CPU, the main PCIe x16 slot and one M.2 slot run at PCIe 4.0. The second M.2 slot is not PCIe 4.0.
Does it have built-in Wi-Fi?
No. Networking is a single 1 Gb Ethernet port, so wireless needs a separate card or USB adapter.
Which CPUs fit the AM4 socket?
It is built for 3rd Gen AMD Ryzen processors on AM4. Check Asus's CPU support list for other AM4 chips before buying.
Can I run two M.2 drives?
Yes. There are two M.2 slots, one of them PCIe 4.0 with a compatible CPU. SATA drives connect through the SATA 6 Gbps ports.
Does it work with Ryzen APUs for video output?
Yes. The board has DisplayPort and HDMI outputs, so a Ryzen processor with integrated graphics can drive a display without a graphics card.
What RGB lighting does it support?
It has an addressable Gen 2 RGB header for LED strips, synced with Aura Sync-capable hardware through Asus software.
