Verdict

The MSI Z170A Krait Gaming 3X is an ATX motherboard built on the Intel Z170 chipset, designed for 6th Gen Intel Core processors and supporting up to 64GB of dual-channel DDR4 memory with speeds up to 3600MHz (O.C.). Key characteristics include high-speed storage via a 32Gb/s M.2 slot and SATA Express, alongside modern connectivity featuring USB 3.1 Gen2 Type-A and Type-C ports. Major pros include its striking monochrome black-and-white aesthetic, durable 'Steel Armor' reinforced PCIe slots for heavy GPUs, and Audio Boost 3 technology with an isolated PCB for superior sound clarity. However, notable cons include a slightly narrow PCB that leaves the right side unsupported by standard ATX mounting holes, potentially causing flex when plugging in cables, and a lack of a physical CMOS reset button on the board itself.

What customers dislike about MSI Z170A Krait Gaming 3X?

  • Narrower ATX PCB design results in only 6 mounting holes, leaving the right edge (RAM/24-pin power area) unsupported and flexible
  • Potential 'Kaby Lake headache' where older BIOS versions require a Skylake CPU to flash for 7th Gen Intel compatibility
  • Lack of a physical CMOS reset button, requiring manual jumper shorting for BIOS recovery
  • Reports of XMP profile instability with certain high-speed RAM kits (e.g., 3000MHz)
  • Some awkwardly placed internal headers, such as the front panel audio connector, which can complicate cable management
