MSI Pro B840-P Wifi DDR5 AMD Motherboard

The MSI Pro B840-P WiFi is an ATX-form AMD motherboard built on the B840 chipset, designed for the AM5 socket and compatible with AMD Ryzen 9000, 8000, and 7000 series desktop processors. It pairs a silver-accented PCB aesthetic that suits both white and black PC builds with a feature set geared toward productivity-focused builders and professionals who demand reliable daily performance. Memory support is a clear strength: four DDR5 UDIMM slots accommodate up to 256 GB total, with JEDEC speeds ranging from 4800 to 5600 MT/s and overclocked profiles reaching up to 8000+ MT/s (1DPC 1R) via AMD EXPO. Dual-channel mode is supported, and the board accepts non-ECC unbuffered memory along with CUDIMM in Clock Driver bypass mode. Connectivity is anchored by integrated Wi-Fi 7, which operates across 2.4 GHz, 5 GHz, and 6 GHz bands (up to 320 MHz channel width) and reaches theoretical wireless throughput of up to 5.8 Gbps. The standard supports 802.11 a/b/g/n/ac/ax/be alongside Bluetooth 5.4 with MLO and 4K-QAM. The wireless module occupies an M.2 Key-E slot and ships pre-installed. A 2.5G wired LAN port rounds out the network options, managed by MSI’s AI LAN Manager software for application-level traffic prioritisation. Storage is handled by two M.2 slots—both CPU-attached and both capable of PCIe 4.0 x4 with Ryzen 9000 or 7000 processors—plus four SATA 6 Gbps ports. RAID 0, 1, and 10 are supported for SATA devices. The primary PCIe x16 slot (PCI_E1) runs at PCIe 4.0 x16 with Ryzen 9000/7000 CPUs, scaling to x8 or x4 for select Ryzen 8000-series variants. The VRM is configured in a 7+2+1 direct digital power phase arrangement fed by an 8-pin CPU power connector, providing stable power delivery for sustained workloads. Cooling management is aided by Frozr AI Cooling, which automatically adjusts fan curves across the board’s five fan headers. M.2 thermal performance is addressed by the tool-free EZ M.2 Shield Frozr II heatsink and the screw-free EZ M.2 Clip II retention system. Audio is delivered by a Realtek ALC897 codec supporting 7.1-channel High Definition Audio via an isolated analogue audio circuit. Display output includes one HDMI 2.1 port supporting up to 4K at 60 Hz for systems with integrated graphics.
