It supports DDR4 memory up to 64 GB and provides three M.2 slots alongside a single PCI Express 3.0 x16 slot and one legacy PCI slot.

Builders who require integrated Wi-Fi or Bluetooth, additional PCI Express x16 slots for multi-GPU, or a bundled I/O shield and accessory kit should look at other options.

LGA 1151 socket with Z390 chipset

The decisive specification is the LGA 1151 socket paired with the Intel Z390 chipset. This combination determines which 8th and 9th Generation Intel Core processors are compatible and unlocks overclocking features for K-series CPUs. Verify your processor matches this socket and chipset before purchasing.
