ASUS TUF GAMING B550M-E AMD B550 Ryzen AM4 Micro ATX motherboard PCIe 4.0 dual M.2

SKU CH-R92T-BB6CZ

Micro ATX AMD B550 board with PCIe 4.0, dual M.2 slots and military-grade components for Ryzen 3000, 4000 and 5000 series CPUs

  • Supports Ryzen 5000, 4000 and 3000 series CPUs via AM4 socket
  • Military-grade components and DIGI+ VRM deliver stable power for high-core-count processors
  • Large VRM heatsink, M.2 heatsink and fanless PCH heatsink keep temperatures low
  • Dual M.2 slots with PCIe 4.0 plus USB 3.2 Gen 2 Type-A enable fast storage and peripherals
  • 1 Gb Ethernet with TUF LANGuard and Turbo LAN optimises online gaming traffic

Foundation for Ryzen 5000 Builds

The ASUS TUF GAMING B550M-E is a Micro ATX motherboard built around the AMD B550 chipset for Socket AM4 processors. It supports Ryzen 5000, 4000 G-Series and 3000 Series desktop CPUs. The board delivers PCIe 4.0 connectivity, dual M.2 slots, USB 3.2 Gen 2 Type-A and front USB 3.2 Gen 1 Type-C support alongside SATA 6 Gbps and DDR4 memory compatibility.

Suited for Compact Gaming Rigs

This board fits builders who want a smaller chassis with strong power delivery and comprehensive cooling. Alloy Chokes, military-grade TUF components and DIGI+ VRM ensure stable operation. A large VRM heatsink, M.2 heatsink and PCH fanless heatsink combine with hybrid fan headers and Fan Xpert 2+ for thermal control. Systems needing integrated Wi-Fi or a full-size ATX layout should consider other options.

PCIe 4.0 Dual M.2 Storage Ready

The single specification that decides fit is PCIe 4.0 support across dual M.2 slots. This enables the highest throughput for compatible SSDs on the platform. If your storage plan relies on that bandwidth, this board meets the requirement; if you only need PCIe 3.0 speeds, a different model may suffice.

Questions about this item

How do I confirm the board is running PCIe 4.0 after setup?

Enter the BIOS and check the M.2 slot speed setting; it should show PCIe 4.0 x4 when a compatible Ryzen 5000 or 3000 series CPU is installed.

What comes in the box and what must I source separately?

The motherboard ships with I/O shield, SATA cables, M.2 screws, and manual; you still need a Ryzen AM4 processor, DDR4 memory, storage drives, and a graphics card if your CPU lacks integrated graphics.

Which B550 chipset variant should I pick for dual M.2 and PCIe 4.0 support?

The TUF GAMING B550M-E includes the B550 chipset with dual M.2 slots and PCIe 4.0 lanes, so this single model covers both features.
