MSI Pro B650-S WIFI ATX Motherboard

The MSI Pro B650-S WIFI is a full-size ATX motherboard built on the AMD B650 chipset, designed to support AMD Ryzen 7000, 8000, and 9000 series desktop processors via the AM5 (LGA 1718) socket. It is a capable foundation for productivity-oriented and performance desktop builds, combining a robust power delivery system with modern connectivity standards. Power delivery is handled by a 12+2 Duet Rail Power System with P-PAK components and dual 8-pin CPU power connectors, providing stable voltage regulation for demanding Ryzen processors. The board's 6-layer PCB is constructed with 2 oz thickened copper traces, supporting signal integrity under sustained workloads. Memory support spans four DDR5 DIMM slots capable of holding up to 256 GB in dual-channel configuration. Supported speeds range from 4800 MHz at JEDEC spec through overclocked profiles reaching 7200+ MHz under a single-dimm-per-channel, single-rank arrangement. AMD EXPO profiles are supported for straightforward memory tuning. Non-ECC, unbuffered DIMMs are required. Storage is served by two M.2 slots—both sourced from the CPU and supporting PCIe 4.0 x4 devices—alongside four SATA 6 Gbps ports with RAID 0 and RAID 1 support for both SATA and NVMe arrays. Expansion slots include one PCIe 4.0 x16 slot from the CPU, one PCIe 4.0 x4 slot from the chipset, and one PCIe 3.0 x1 slot. Connectivity is a strong point: the integrated AMD Wi-Fi 6E module supports 2.4 GHz, 5 GHz, and 6 GHz bands (6 GHz subject to regional regulations), MU-MIMO TX/RX, and 802.11 a/b/g/n/ac/ax standards. Bluetooth 5.3 is also included. Wired networking is handled by a Realtek 8125BG 2.5 Gigabit LAN controller. The rear I/O panel provides HDMI 2.1 (4K 60 Hz, with compatible APU) and DisplayPort 1.4 (4K 60 Hz, with compatible APU), a USB 3.2 Gen 2x2 Type-C port at 20 Gbps, three USB 3.2 Gen 2 Type-A ports at 10 Gbps, four USB 3.2 Gen 1 Type-A ports at 5 Gbps, a Flash BIOS button, 2.5G LAN, and 7.1-channel audio via the Realtek ALC897 codec. Front-panel headers add four USB 2.0, two USB 3.2 Gen 1 Type-A, one USB 3.2 Gen 2 Type-C, and one USB 3.2 Gen 2x2 Type-C internal connector. Four EZ Debug LEDs assist with rapid troubleshooting. RGB ecosystem support includes two ARGB V2 headers and two standard RGB headers. A TPM 2.0 pin header is present for security-conscious builds.
