rigvelaASUS TUF GAMING B550-PLUS
M.2 slots and conditions
First check where the existing SATA drives are connected. After adding an SSD to M.2_2, SATA ports 5 and 6 cannot still be counted as usable. This page covers B550-PLUS, not the WIFI or WIFI II versions.
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 |
|---|---|---|
| M.2_1 | PCIe 4.0 / 3.0 x4 + SATAModule lengths: 2242 / 2260 / 2280 / 22110 | PCIe mode depends on the installed CPU. |
| M.2_2 | PCIe 3.0 x4 + SATAModule lengths: 2242 / 2260 / 2280 / 22110 | When M.2_2 is populated, SATA6G_5 and SATA6G_6 are disabled. The rule concerns an occupied M.2_2, not only a SATA SSD. |
What to check on this board
If a SATA drive disappears after adding a second M.2 drive, compare its port number with this rule. Shut down and use the manual before changing connections; do not format a drive to test port sharing.
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.
