ASUS TUF B550 Micro ATX with Ryzen 5 5600X

This bundle pairs a Micro ATX B550 motherboard with a Ryzen 5 5600X processor. The board uses the AM4 socket and AMD B550 chipset. It provides four DDR4 memory slots supporting speeds up to 4866 MHz when overclocked and a maximum capacity of 128 GB. Integrated Wi‑Fi and HDMI 2.1 are included.

For AM4 builders needing compact Wi‑Fi

The combination suits builders who want a small‑form‑factor system with wireless networking and a 65 W six‑core CPU. It supports dual‑channel DDR4, four SATA 6 Gb/s ports and two M.2 slots for storage expansion. Users requiring full‑size ATX layouts, multi‑GPU support or newer socket platforms should consider other options.

PCIe 4.0 x16 slot for Ryzen 5000 series

The single PCIe 4.0 x16 slot operates at full speed only with Ryzen 5000 or 3000 series desktop processors. With Ryzen 5000 G‑Series or 4000 G‑Series CPUs the slot runs at PCIe 3.0 x16. This distinction determines graphics performance and is the key specification to verify before purchase.

Questions about this item

What size case and power connectors does this micro ATX board require?

The board uses micro ATX dimensions, a 24-pin ATX power connector and an 8-pin EPS connector.

Which CPU power phase and BIOS step are critical when installing the 65 W 6-core processor?

Connect the 8-pin EPS cable, seat the processor in the AM4 socket, then update the BIOS before first boot so the 3.7 GHz 65 W CPU is recognised.

Which memory type and maximum capacity should I plan for future upgrades?

Four 288-pin DDR4 slots support up to 128 GB in dual-channel mode.
