What we like about ASRock Fatal1ty X99M Killer

  • High build quality with ASRock Super Alloy components and Nichicon 12K Platinum caps
  • Excellent overclocking potential supported by a robust 12-phase power design
  • Compact Micro-ATX form factor that doesn't sacrifice high-end X99 features
  • Dual networking options featuring both Killer E2200 and Intel Gigabit LAN
  • Fast storage support via the 'Ultra M.2' slot (PCIe Gen3 x4)
  • Value-added accessories, including a 3-month XSplit premium membership

What we don't like about ASRock Fatal1ty X99M Killer

  • Awkward placement of the 8-pin CPU power connector can be blocked by large CPU coolers
  • Front-panel audio header is positioned far into the bottom-rear corner, causing reach issues in some cases
  • Limited to only four RAM slots due to the Micro-ATX size, capping total capacity compared to full ATX boards
  • Killer LAN drivers have been reported by some users to be less stable or more intrusive than standard Intel drivers
  • Overclocking can automatically ramp fans to maximum speed, leading to high noise levels

Verdict

The ASRock Fatal1ty X99M Killer is a high-performance Micro-ATX motherboard designed for the Intel LGA 2011-3 socket, supporting Core i7 and Xeon E5 series processors with an robust 12-phase power design. It features four DDR4 slots supporting quad-channel memory up to 3000MHz (OC), dual gigabit LAN (Intel and Killer E2200), and ten SATA3 ports alongside an Ultra M.2 slot for high-speed storage. Main pros include its premium Super Alloy components like 60A power chokes and Nichicon 12K platinum caps for enhanced stability, Purity Sound 2 audio for superior 7.1 channel output, and a compact form factor that doesn't compromise on workstation-class features like ECC memory support. However, cons include limited expansion potential with only three PCIe slots due to its small size and the potential for clearance issues when using oversized CPU coolers or large GPUs in the top slot.
