Mini ITX Z490 board for 10th Gen Intel

This motherboard uses the LGA 1200 socket and Intel Z490 chipset to support 10th Generation Intel Core, Pentium Gold and Celeron processors. It targets builders who want a high-end feature set inside a Mini ITX chassis. The board includes Intel Thunderbolt 3 via the JHL7540 controller and WiFi 6 through the pre-installed Intel AX201 module.

Two DDR4 slots and dual M.2 layout

Only two 288-pin DDR4 slots are present, so memory upgrades are limited to a maximum of 64 GB in dual-channel mode. The first M.2 slot shares bandwidth with the second SATA port; populating it with a SATA M.2 drive disables that SATA connector. The pre-installed Wi-Fi module occupies the Key-E M.2 slot, leaving the two Key-M slots for storage.

64 GB memory ceiling and 5000+ MHz headroom

Dual-channel DDR4 tops out at 64 GB, with validated speeds of 2933, 2666 and 2133 MHz. One DIMM per channel can reach 5000+ MHz with single-rank modules or 4600+ MHz with dual-rank modules. A single PCIe 3.0 x16 slot and four SATA 6 Gbps ports handle expansion, while 2.5 Gbps LAN and WiFi 6 on 160 MHz channels provide network throughput up to 2.4 Gbps.

Highlights

  • Supports 10th Gen Intel Core processors via LGA 1200 socket
  • Dual-channel DDR4 memory up to 64 GB with 5000+ MHz overclocking headroom
  • Two M.2 slots for PCIe 3.0 x4 storage devices in 2280 form factor
  • Integrated WiFi 6 and 2.5 Gbps LAN for high-speed networking
  • 1-channel Realtek ALC1220 audio with S/PDIF output

Questions about this item

How do I verify the 2.5 Gbps LAN and WiFi 6 are active after first boot?

Open Device Manager and confirm the Realtek RTL8125B 2.5Gbps controller and Intel AX201 wireless adapter both show no errors; the WiFi 6 module is pre-installed in the M.2 Key-E slot and should list 2.4 GHz / 5 GHz 160 MHz bands.

Which items ship in the box and which must I purchase separately?

The board includes the pre-installed Intel AX201 WiFi 6 module, I/O shield, SATA cables and manuals; you must buy an LGA 1200 CPU, DDR4 memory modules, M.2 2280 storage and a CPU cooler separately.

Which M.2 slot should I use for a PCIe 3.0 x4 2280 drive if I also need all four SATA ports?

Install the drive in the M2_2 slot; M2_1 shares bandwidth with SATA2, so using M2_2 keeps all four SATA 6 Gb/s ports available.
