M.2 slots and conditions
The M in B650M matters: this model lists 2260 and 2280 SSDs for both connectors. The full-size B650 GAMING PLUS WIFI documentation cannot stand in for this board’s specifications.
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 4.0 x4Module lengths: 2260 / 2280 | Verify occupancy and physical installation separately. |
| M2_2 | PCIe 4.0 x4Module lengths: 2260 / 2280 | With Ryzen 8500/8300: PCIe 4.0 x2. The connector is not disabled. |
What to check on this board
With Ryzen 8500/8300, M2_2 is listed as operating with two PCIe 4.0 lanes. That mode alone does not mean an SSD will be undetected. If a drive is missing, check its NVMe interface, installation, BIOS and the exact board documentation separately.

Answers for MSI B650M GAMING PLUS WIFI. Updated .
How many M.2 SSD slots are there?
Two: M2_1 and M2_2. That is the connector count, not the number of free positions in your PC. Check where your current SSD is installed. The separate Key E socket for the Wi-Fi module is not another SSD position.
My SSD is in M2_1. Can I add a 2280 NVMe drive to M2_2?
M2_2 lists support for 2280 PCIe NVMe drives. With a Ryzen 8500/8300 processor, MSI specifies PCIe 4.0 x2 for this connector; it remains available. Before buying, check that M2_2 is empty and confirm mounting and heatsink clearance in the manual. Select your CPU and M2_2 in the checker below to see the connection conditions.
Check M2_2 with your CPU →Does this board support a 22110 SSD?
MSI lists 2260 and 2280 for both M2_1 and M2_2; 22110 is not listed for this B650M model. Do not use the mounting list of the full-size B650 GAMING PLUS WIFI instead. Check the complete board name before choosing a longer drive.
I have B650 GAMING PLUS WIFI →Can I reuse an M.2 SATA SSD?
MSI lists PCIe storage for these two M.2 connectors, not M.2 SATA. A matching length does not change the drive’s interface. Look up the exact SSD model before moving it; a 2.5-inch SATA drive uses a separate data and power connection.
Tell SATA, NVMe and M.2 apart →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.

For another revision or updated documentation, recheck conditions with the manufacturer. This reference covers storage, not every motherboard specification.
