M.2 slots and conditions
The three connectors list the same SSD lengths but different connections. This page covers B650M Pro RS; the WiFi variant needs its own documentation.
Storage sources reviewed: . An individual build and installed BIOS have not been tested.
Connector table
On a narrow screen, scroll the table sideways. Match connector names to the board and manual.
| Connector | Connection and length | Conditions |
|---|---|---|
| M2_1 | PCIe 5.0 x4Module lengths: 2260 / 2280 | PCIe mode depends on the installed CPU. |
| M2_2 | PCIe 4.0 x4Module lengths: 2260 / 2280 | Verify occupancy and physical installation separately. |
| M2_3 | PCIe 4.0 x2Module lengths: 2260 / 2280 | Verify occupancy and physical installation separately. |
What to check on this board
ASRock lists two PCIe lanes for M2_3. It cannot be counted as another Gen4 x4 connector. M2_1’s mode with the installed CPU remains a separate check.
Work through your conditions
Choose the SSD interface and length, then the known configuration details. CPU options reflect the RigVela catalogue and recorded family support; the required BIOS remains a separate check. Notes are calculated in your browser. The selected CPU, SSD model, connector, interface and length, and shared-connection choice can appear in reference links when navigating or changing language. Your build is not changed.
Before installation
Verify exact model and revision, installed BIOS, current connections, mounting, heatsink and height clearance. A disabled connector, an occupied position and an unsuitable interface are different problems. Do not erase a drive to diagnose its connection.
Documentation
For another revision or updated documentation, recheck conditions with the manufacturer. This reference covers storage, not every motherboard specification.
