Bundle platform
This motherboard and CPU bundle pairs an AMD B550 Micro-ATX board with a Ryzen 5 5500 six-core processor. The board delivers a PCIe 4.0 x16 slot and dual M.2 sockets for fast storage. Integrated Intel Wi-Fi 6 and 2.5 Gbps LAN handle networking without extra cards. The 65 W CPU fits compact builds and standard coolers.
Target builder
Builders wanting a ready-to-run AM4 foundation for 1080p gaming or productivity will appreciate the matched components. The bundle suits DDR4 memory kits up to 128 GB and leaves two PCIe x1 slots for add-in cards. Users needing integrated graphics or more than six cores should select a different processor.
Deciding spec
The Ryzen 5 5500 lacks integrated graphics, so a discrete GPU is mandatory for any video output. The board’s HDMI and DisplayPort connectors only function with APUs. Confirm your graphics card choice before ordering this combo.

Questions sur cet article
Will my DDR4 3200 MHz RAM run at its rated speed with the Ryzen 5 5500 on this board?
Yes, the board supports DDR4 3200 MHz by JEDEC with Ryzen 5000 series processors, so your modules will operate at that speed without manual tuning.
How can I verify the Intel Wi-Fi 6 AX200 module is active after assembly?
Open Device Manager in Windows; the adapter appears as Intel Wi-Fi 6 AX200 and should show a 2.4 Gbps link rate when connected to a 5 GHz 160 MHz network.
Does the bundle include a CPU cooler for the 65 W Ryzen 5 5500?
No, the package contains only the motherboard and processor; a compatible AM4 cooler must be purchased separately.
