Green Micro ATX motherboard with black heatsinks and silver LGA 1200 socket

GIGABYTE

GIGABYTE Z490M LGA 1200 Micro ATX Intel motherboard

SKU CH-7EGH-BJ62J

Micro ATX Intel Z490 board with LGA 1200 socket supporting up to 128 GB DDR4 and PCIe 4.0 hardware design

  • Supports up to 128GB DDR4 dual-channel memory
  • Intel Z490 chipset for LGA 1200 socket CPUs
  • Micro ATX form factor fits compact builds
  • 5mm thermal pad improves MOSFET heat dissipation
  • PCIe 4.0 hardware design enables high-bandwidth NVMe storage

Compact Z490 board for LGA 1200 builds

This micro-ATX motherboard pairs the Intel Z490 chipset with an LGA 1200 socket, supporting dual-channel DDR4 memory up to 128 GB. It targets builders who want Z490 overclocking features in a smaller chassis without full-size ATX dimensions.

4+2 hybrid digital VRM with low RDS(on) MOSFETs

The power phase design uses low RDS(on) MOSFETs to cut switching losses and lower component temperatures under load. An enlarged heatsink with a 1.5 mm thermal pad increases dissipation surface area, while the integrated I/O armour adds extra thermal mass for sustained operation.

PCIe 4.0-ready layout with Gen3 M.2 NVMe support

The board implements PCIe 4.0-grade hardware traces for graphics and storage, though the M.2 connectors operate at PCIe Gen3 x4 speeds for NVMe drives. Micro-ATX sizing frees expansion slots in compact cases, while the Z490 chipset retains CPU overclocking control and multi-GPU capability for compatible processors.

Questions about this item

How do I install the LGA 1200 CPU and what step is often missed?

Align the notches on the processor with the socket keys, lower the retention arm gently, and do not forget to remove the plastic protective cover from the socket before seating the chip.

Which component on the Z490M board will need replacement first after prolonged use?

The 1.5 mm thermal pad on the 4+2 hybrid digital VRM heatsink can degrade over time; replacing it restores optimal MOSFET heat dissipation.

What bandwidth limit appears first when running sustained NVMe PCIe Gen3 x4 workloads?

The M.2 connectors operate at PCIe Gen3 x4 speeds, so sequential throughput caps at the Gen3 x4 ceiling before the PCIe 4.0 hardware design becomes a factor.
