AM4 socket board for Ryzen 3000, 4000, 5000 series

This micro-ATX motherboard uses the AMD B550 chipset and an AM4 socket. It is built for Ryzen 3000, 4000 and 5000 series processors. The board provides one PCIe 4.0 x16 slot, one PCIe 3.0 slot, two M.2 slots and four SATA 6Gb/s ports. Video output includes one HDMI and one DisplayPort connector.

Check CPU cooler clearance and DDR4 memory speed

Verify that your CPU cooler fits a micro-ATX layout around the AM4 socket area. The board runs DDR4 memory and supports overclocked speeds up to DDR4 4000+. Confirm your existing modules are DDR4; other generations will not fit. Ensure your power supply has the required ATX and CPU power connectors for the 8+2 phase design.

8+2 phase power with rear USB Type-C

An 8+2 intelligent power delivery design feeds the CPU and is cooled by a premium module heatsink. The rear I/O includes a high-speed USB Type-C port alongside standard connections. A reserved M.2 key-E slot allows a Wi-Fi and Bluetooth module to be added later. Dual M.2 slots and four SATA ports give multiple storage options.

Questions about this item

What comes in the box with the Sapphire PULSE B550M and do I need to buy a CPU cooler separately?

The motherboard ships with the board itself, I/O shield, SATA cables and documentation; a compatible AM4 cooler must be purchased separately for any Ryzen 5000 Series processor.

Should I choose the single PCI-E 4.0 x16 slot or the dual M.2 3.0 slots for my primary graphics card?

Install the graphics card in the PCI-E 4.0 x16 slot; the two M.2 3.0 slots are intended for storage drives only.

What does the DDR4 4000+ overclocked rating mean once the board is running a Ryzen 5000 Series CPU?

It indicates the board can run memory above 4000 MT/s when manually tuned in the BIOS; actual speed depends on the CPU memory controller and the specific DDR4 modules used.
