Selling a lightly used MSI MAG B650 Tomahawk WiFi ATX motherboard, model MS-7D75.

This motherboard was removed from a prebuilt PC that was upgraded to a newer AM5 platform. During inspection, I noticed 4–6 CPU socket pins that were sitting lower than the rest and carefully straightened them. It was then briefly used as a reference and validation board for professional GPU and motherboard repair work, where it served to test repaired graphics cards and verify trace fixes against a known-good platform before returning hardware to customers. It has seen no mining, no daily workstation loads, and no long-term high-stress workloads.

The motherboard is in used, very good condition and includes a transferable manufacturer warranty tied to MSI's serial number policy.

Per MSI specs, this model features the AMD B650 chipset, AM5 socket (Ryzen 7000 series), ATX form factor, 4x DDR5 slots up to 128GB / 6400+ MHz OC, 14+2+1 Duet Rail VRM with 80A SPS, 2x PCIe 4.0 x16 slots, 3x M.2 slots (Lightning Gen4, 2 with Shield Frozr), 6x SATA, Wi-Fi 6E, Bluetooth 5.3, 2.5Gb LAN, USB 3.2 Gen 2x2 Type-C (20Gbps), HDMI, DisplayPort, and Audio Boost 5.
