MSI PRO B850-S EVO WIFI — AMD B850 ATX for Socket AM5 with Wi-Fi 7 and 5Gb LAN
AMD B850 / Socket AM5PCIe 5.0 x16 + PCIe 5.0 M.2Wi-Fi 7 + Bluetooth 5.4Realtek 5Gb LAN
The MSI PRO B850-S EVO WIFI is a full-size ATX motherboard on the AMD B850 chipset for Socket AM5, built for professional and workstation systems that need fast storage and fast networking without gaming-board styling. It carries the part number 7E97-001R (EAN 4711377422765) and supports AMD Ryzen 9000, 8000 and 7000 Series processors, with four DDR5 UDIMM slots taking up to 256 GB and rated to 8200+ MT/s when overclocked. Storage covers three M.2 slots, the first of them PCIe 5.0 x4, plus four SATA 6 Gb/s ports with RAID 0, 1, 5 and 10. Networking is unusually strong for the class: a Realtek 8126VB 5Gb Ethernet controller alongside Wi-Fi 7 with Bluetooth 5.4. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
Socket AM5 means DDR5 memory only — AM4 processors and DDR4 modules are not compatible. The three M.2 slots differ: M.2_1 is PCIe 5.0 x4, M.2_2 is PCIe 4.0 x4 and M.2_3 is only PCIe 4.0 x2, so put your fastest drive in M.2_1. Only M.2_2 accepts longer 22110 drives. RAID 5 requires a Ryzen 9000 Series processor. The PCIe generation of the main x16 slot depends on the CPU — PCIe 5.0 with Ryzen 9000 and 7000, lower with Ryzen 8000 parts. Display output is one HDMI 2.1 and one DisplayPort 1.4, both capped at 4K 60 Hz, and both need a CPU with integrated graphics. Onboard audio is a Realtek ALC897, a mainstream codec rather than a high-end one. The board is full ATX at 304.8 x 243.84 mm. To get the full benefit of the 5Gb LAN port you need a 5Gb-capable switch or NAS.
Best For
✓ Workstations that move large files over a 5Gb network
✓ Ryzen 9000 builds wanting PCIe 5.0 graphics and storage
✓ Professional systems where styling matters less than I/O
✓ Builds needing three NVMe drives plus four SATA disks
✓ Offices upgrading beyond gigabit without adding a network card
✓ Systems using RAID 5 across NVMe drives on Ryzen 9000
Key Features
Realtek 5Gb LAN plus Wi-Fi 7
A Realtek 8126VB controller gives 5 Gigabit wired Ethernet — twice the 2.5Gb that most B850 boards offer — alongside a Wi-Fi 7 module covering 2.4, 5 and 6 GHz at up to 2.9 Gbps with Bluetooth 5.4. For anyone shifting large project files to a NAS, that wired port is the single most useful thing on this board.
Three M.2 slots with PCIe 5.0 on the first
M.2_1 runs PCIe 5.0 x4 straight from the CPU for a Gen 5 NVMe drive, M.2_2 runs PCIe 4.0 x4 and takes drives up to 22110 in length, and M.2_3 adds a PCIe 4.0 x2 slot from the chipset. Four SATA 6 Gb/s ports remain, with RAID 0, 1, 5 and 10 available on NVMe (RAID 5 on Ryzen 9000).
Four DDR5 slots to 256 GB with EXPO
Four UDIMM sockets take up to 256 GB of DDR5 in dual channel, with AMD EXPO one-click profiles and a rated ceiling of 8200+ MT/s in a single-rank, one-per-channel configuration. CUDIMM modules are supported in clock driver bypass mode.
Generous USB across front and rear
The rear panel carries a 10 Gbps USB Type-C port, two 10 Gbps Type-A, two 5 Gbps Type-A and four USB 2.0 ports, while front headers add a 10 Gbps Type-C connector, two 5 Gbps ports and four USB 2.0. That is enough to run a full desk of peripherals without a hub.
Technical Specifications
Frequently Asked Questions
Singular Expert Insight
The 5Gb LAN port is what separates this board from the crowd. Most B850 boards give you 2.5Gb, which is already a real upgrade over gigabit, but if you regularly push video projects or backups to a NAS the jump to 5Gb is the one that changes how long you sit waiting. Everything else here is competent rather than flashy: PCIe 5.0 for graphics and the first M.2, three NVMe slots, four DDR5 slots to 256 GB, and an ALC897 codec that is fine for headsets but not an audiophile part. That is a sensible set of priorities for a work machine. Pair it with a matched two-module DDR5 memory kit so you keep two slots free, and a Gen 5 drive from our internal SSDs range in M.2_1. Just remember the third M.2 slot is PCIe 4.0 x2, so it is not the place for your scratch disk.
Buyer's Guide
Buy it if
You want a professional-looking full ATX AM5 board with 5Gb wired networking and Wi-Fi 7 built in, PCIe 5.0 for graphics and a Gen 5 NVMe drive, and three M.2 slots with four DDR5 slots to 256 GB.
Skip it if
You want premium onboard audio, more than three M.2 slots, USB4 or Thunderbolt, or display outputs above 4K 60 Hz from the integrated graphics.
Also consider
The MSI MAG B850 TOMAHAWK WIFI for a better audio codec and an 8K-capable HDMI output, or the MSI PRO X870E-S EVO WIFI if you need USB4 at 40 Gbps.
