MSI B850 GAMING PLUS WIFI PZ review

This is an ATX board on the AMD B850 chipset with an AM5 socket. It supports Ryzen 9000, 8000 and 7000 series desktop processors. It takes DDR5 in four DIMM slots, up to 256GB, and lists support for speeds up to 8200MHz. Memory is non-ECC and dual-channel.

Owners describe it as a mid-range board, and the praise they give it is about what it includes: fast networking and a capable power design. The main complaint is about video output.

Networking is the strongest part of the specification. The board has Wi-Fi 7 and a 5Gbps wired port, which MSI's spec page lists as a Realtek 8126VB. Owners single out this pairing as a highlight on a mid-range board. Anyone with a multi-gig switch or a fast NAS gets use from the wired port without adding a card.

Rear USB is more modest. The rear panel has a USB-C port running at 10Gbps, and it also carries 5Gbps and 10Gbps Type-A ports plus USB 2.0 ports. Inside, there is a front USB 5Gbps Type-C header, along with four USB 3.2 Gen 1 connectors and four USB 2.0 connectors. For a build with a few external SSDs and a case with front USB-C, that covers the basics.

The board has no integrated graphics listed on the platform side, and video output is DisplayPort 1.2 (HBR2) only. No HDMI port is listed, and owners flag this as their main complaint. If your monitor or capture device only takes HDMI, you will need a graphics card with HDMI output or a DisplayPort-to-HDMI adapter. With a discrete card driving the display, the limitation matters much less.

There are three M.2 Key M slots. M.2_1 connects to the CPU and runs up to PCIe 5.0 x4, accepting 2260 and 2280 drives. M.2_2 also connects to the CPU, runs up to PCIe 4.0 x4 and accepts 22110 and 2280 drives. M.2_3 connects to the chipset at up to PCIe 4.0 x2, for 2260 and 2280 drives. Only one slot gets PCIe 5.0, so a second Gen5 drive is not possible. The longer 22110 support on M.2_2 helps if you use enterprise-length drives.

Four SATA 6Gb/s ports come from the chipset. With the three M.2 slots, the board lists seven storage drives in total. RAID levels 0, 1, 5 and 10 are supported. That suits a workstation or a small home server with a few disks, although the four SATA ports limit a large bulk-storage build.

The board has a single PCIe x16 slot. Listings differ on its generation, so check MSI's page for your CPU if graphics bandwidth matters to you.

MSI describes the power system as a 12+2+1 Duet Rail design: 12 Vcore phases, 2 SOC phases and 1 MISC phase. Two 8-pin CPU connectors feed it. Owners praise the stable power delivery for overclocking and credit the 12-phase VRM and the thermal pads.

The Flash BIOS button works with only a power supply connected. No CPU or memory needs to be fitted. That helps when you buy a board that needs an update before it will boot a newer Ryzen chip. A Clear CMOS button is also fitted, which saves reaching for a jumper after a failed memory overclock. Owners raise no recurring stability or memory problems.

The board suits a Ryzen build with a discrete graphics card, a fast wired network and a mix of NVMe and SATA storage. The Wi-Fi 7 and 5Gbps LAN make it a sensible base for a networked workstation or a compact homelab desktop. The single Gen5 M.2 slot, DisplayPort-only video and limited rear USB are the trade-offs to weigh.
