Socket LGA 1200 platform

This ATX motherboard uses the Intel Z490 chipset and an LGA 1200 socket for 10th Gen Intel Core processors. Four DDR4 slots support up to 128GB of memory in dual-channel mode. Dual M.2 slots, four SATA 6Gb/s ports and USB 3.2 Gen 2 Type-A provide fast storage and peripheral connections. Realtek ALC887 audio delivers 8-channel output.

Builders wanting Z490 features without onboard Wi-Fi

The board suits DIY builders who need CPU overclocking headroom, dual PCI Express 3.0 x16 slots and Thunderbolt 3 header support. Users requiring integrated wireless, 1Gbps LAN only, or a smaller form factor should consider other models. The M.2 Key E slot accepts a separate Wi-Fi module if wireless is added later.

LGA 1200 socket for 10th Gen Intel Core

The LGA 1200 socket is the single specification that determines CPU compatibility. Only 10th Gen Intel Core processors fit this socket; newer or older generations are not supported. Verify your processor generation before purchase.

Questions about this item

How hot or loud does the VRM heatsink and Fan Xpert 4 setup get during all-day loads?

The board uses a VRM heatsink, PCH heatsink and hybrid fan headers managed by Fan Xpert 4 to keep temperatures and noise in check under sustained workloads.

Which processor and memory must I already have to use this LGA 1200 board?

You need a 10th Gen Intel Core CPU for the LGA 1200 socket and DDR4 modules; the board supports up to 128 GB across four slots at 2666 MHz standard.

Will my existing SATA drives and PCIe 3.0 add-in cards work without changes?

Yes — four SATA 6 Gb/s ports, two PCIe 3.0 x16 slots and four PCIe x1 slots accept current drives and expansion cards directly.
