Intel Z890 Back-Connect ATX Motherboard

The MSI PRO Z890-S WIFI PZ is a back-connect ATX motherboard built on the Intel Z890 chipset for LGA 1851 processors. It supports Intel Core Ultra Processors Series 2 and provides four DDR5 slots with a maximum capacity of 256 GB. Overclocked memory speeds reach 8800+ MT/s in a 1DPC 1R configuration.

Suited for High-Speed Storage and Network Builds

This board suits builders who need one PCIe 5.0 x16 slot, one PCIe 5.0 M.2 slot and two additional PCIe 4.0 M.2 slots for fast NVMe storage. It also provides Thunderbolt 4 at 40 Gbps, USB 20 Gbps Type-C, Intel Wi-Fi 7 and 2.5 Gbps LAN. Users requiring more than one PCIe 5.0 x16 slot should consider other options.

Deciding Specification: Single PCIe 5.0 x16 Slot

The defining specification is the single PCIe 5.0 x16 slot wired from the CPU. If the build requires only one graphics card or PCIe 5.0 add-in card, this motherboard delivers the platform bandwidth and connectivity. If a second full-bandwidth x16 slot is needed, a different Z890 model must be selected.

Highlights

  • Supports Intel Core Ultra Series 2 processors via LGA 1851 socket
  • DDR5 memory overclocking up to 8800+ MT/s with Memory Boost technology
  • PCIe 5.0 x16 slot plus M.2 Gen5 for fastest storage and graphics
  • Intel Wi-Fi 7 with 320 MHz channels reaching 5.8 Gbps
  • Thunderbolt 4 at 40 Gbps plus USB 20 Gbps and 2.5G LAN

Questions about this item

Will this board fit a standard ATX case with the back-connect layout?

The PRO Z890-S WIFI PZ uses a back-connect ATX form factor, so it mounts in any standard ATX chassis using the usual nine standoff positions.

Which power connectors must be plugged in before first boot, and which one do builders often forget?

Connect the 24-pin ATX_PWR, both CPU_PWR 8-pin headers, and the PCIe_PWR 8-pin for the primary PEG slot; the extra PCIe_PWR is the one most often missed.

The Wi-Fi 7 module sits in an M.2 Key-E slot — can it be upgraded later?

Yes, the Intel Wi-Fi 7 card is pre-installed in the M.2 Key-E slot and can be replaced with another Key-E module when a newer standard arrives.
