The MSI Pro Z890-S WiFi uses an LGA 1851 CPU socket paired with the Z890 chipset and follows the standard ATX form factor, measuring 304.8 mm wide and 243.8 mm tall. It supports a single CPU and has no integrated CPU or integrated graphics. The board includes Wi-Fi 7 (802.11be) along with backward-compatible wireless standards down to Wi-Fi 4, as well as Bluetooth 5.4, though aptX is not supported. Video output is handled through an HDMI 2.1 connector, and the board features RGB lighting and supports easy overclocking. On the other hand, it does not include a dual BIOS or an easy CMOS reset option. A three-year warranty is provided with the board.
This board accommodates DDR5 memory across four slots arranged in a dual-channel configuration, with a maximum capacity of 256 GB. Standard RAM speeds top out at 4800 MHz, while overclocking can push that figure up to 8600 MHz. ECC memory is not supported on this board.
The rear I/O panel offers six USB 3.2 Gen 1 Type-A ports for standard high-speed connectivity, alongside one USB 3.2 Gen 2x2 Type-C port and one USB 4 40 Gbps port. There is also one Thunderbolt 4 port, while Thunderbolt 3, USB 3.2 Gen 2 Type-A, USB 3.2 Gen 1 Type-C, USB 2.0, and USB 4 20 Gbps ports are absent. Video output is covered by one HDMI output and one DisplayPort, with no DVI or VGA connectors present. Networking is handled through a single RJ45 port, and there are no eSATA or PS/2 ports on this board.
For internal storage, the board provides three M.2 sockets and four SATA 3 connectors, while SATA 2 and U.2 sockets are not included, and there is no mSATA connector. USB expansion headers consist of two USB 3.2 Gen 1 connectors and two additional USB 3.0 connectors for front-panel or accessory use, along with four USB 2.0 expansion ports. Cooling is well-supported with six fan headers spread across the board, and a TPM connector is present for security module use.
The board includes one PCIe 5.0 x16 slot and two PCIe 4.0 x16 slots for expansion cards, along with one PCIe x1 slot for smaller add-in cards. There are no PCIe 3.0 x16, PCIe 2.0 x16, PCIe x4, PCIe x8, or legacy PCI slots present on this board.
The onboard audio supports 7.1-channel output and is accessible through three audio connectors. There is no S/PDIF Out port on this board.
The board supports RAID 0, 1, 5, and 10 (1+0) configurations, covering a range of performance and redundancy needs. RAID 0+1 is not supported.
