Micro-ATX AM5 motherboard with DDR5

The ASRock B650M Pro RS WiFi is a micro-ATX board built around the AMD B650 chipset for Socket AM5 processors. It accepts Ryzen 7000, 8000 and 9000 series CPUs and provides four DDR5 slots supporting up to 192 GB of memory. Integrated Wi-Fi and Bluetooth are included, along with HDMI and DisplayPort outputs for processors with onboard graphics.

Suits compact Ryzen builds needing Gen5 storage

This board fits small-form-factor cases and users who want a single PCIe 5.0 M.2 slot for the fastest NVMe drives. It also offers a second PCIe 4.0 M.2 slot and a third PCIe 4.0 x2 slot, plus four SATA 6 Gb/s ports. Builders requiring multiple full-size PCIe 4.0 x16 slots or legacy PCI support should look at full-size ATX alternatives.

One Blazing M.2 socket at PCIe Gen5 x4

The primary M.2 socket (M2_1) runs at PCIe 5.0 x4, delivering up to 128 Gb/s bandwidth for a 2280 NVMe drive. The second socket (M2_2) operates at PCIe 4.0 x4 (64 Gb/s) and the third (M2_3) at PCIe 4.0 x2 (32 Gb/s). This hierarchy determines which drive gets the maximum sequential throughput.

Questions about this item

Can I reuse my current DDR5 memory kit with this AM5 board and reach the rated frequency?

The board supports DDR5 ECC and non-ECC un-buffered modules up to 7200+(OC) across four 288-pin slots with dual-channel operation.

What LEDs or POST codes confirm the B650M Pro RS WiFi has initialised correctly?

After power-on the on-board Dr.Debug display shows a two-digit POST code; a steady CPU or DRAM LED indicates the corresponding component is detected.

Which cables, brackets or modules are included and what must I source separately?

The open-box unit ships with the motherboard, I/O shield, SATA cables and driver disc; Wi-Fi antennas, M.2 screws and CPU cooler mounting hardware are not included.
