Z490 Mini-ITX Board for 10th Gen Intel

The ASRock Z490 Phantom Gaming-ITX/TB3 fits the LGA 1200 socket and the Intel Z490 chipset. It supports 10th Gen Intel Core processors and future generation CPUs on the same platform. The board uses a Mini-ITX layout with two 288-pin DDR4 slots for up to 64 GB of dual-channel memory. Onboard video output works only with a CPU that includes integrated graphics.

Compact Builders and Small-Case Owners

This motherboard suits builders who need a full Z490 feature set in a Mini-ITX footprint. It provides one PCI Express 3.0 x16 slot, four SATA 6.0 Gb/s ports and two Ultra M.2 sockets for storage flexibility. Users requiring more than two memory slots, multiple graphics cards or a larger ATX form factor should look at a different board.

LGA 1200 Socket Defines CPU Compatibility

The LGA 1200 socket is the single specification that decides whether this board fits your processor. Only Intel CPUs designed for this socket will install and operate correctly. Verify your CPU matches LGA 1200 before purchasing.

Questions about this item

What Mini-ITX case clearances are needed for the LGA 1200 socket and 15µ gold PCIe slot?

The board uses the LGA 1200 socket with a 15µ gold contact PCIe x16 slot; ensure the case allows standard Mini-ITX mounting holes and enough height for the CPU cooler and a full-length graphics card.

How is the bundled WiFi-802.11ax module installed in the vertical M.2 Key E socket?

Insert the supplied WiFi-802.11ax module into the vertical M.2 Key E socket on the rear I/O and secure it with the screw; the step often missed is attaching the two antenna cables to the module before closing the case.

When should the M.2 2280 or 2260 drive in the Ultra M.2 sockets be replaced or upgraded?

Replace or upgrade the M.2 drive if it reaches its write-endurance limit, shows SMART errors, or no longer provides the capacity or PCIe Gen3 x4 32 Gb/s speed required by the workload.
