Third-party reviews

What customers like about ASUS X99-A II

  • Excellent value for high-end enthusiast features at its price point
  • Comprehensive connectivity including USB 3.1 Type-A/C, M.2, and U.2 slots
  • Solid audio performance with the Crystal Sound 3 solution
  • Aura RGB lighting and customizable headers for improved aesthetics
  • Reinforced PCIe 'SafeSlot' design for better heavy-GPU support
  • User-friendly BIOS and informative, well-written manual

What customers don't like about ASUS X99-A II

  • Higher power consumption compared to some competing X99 boards
  • Overclocking can be trickier to dial in than on previous platforms
  • CPU socket is very close to RAM slots, causing clearance issues with large air coolers
  • Mixed reports on long-term reliability and ASUS customer service/RMA quality
  • Initial setup can be complex for users unfamiliar with the X99/Broadwell-E platform

Verdict

The Asus X99-A II is a high-performance ATX motherboard designed for Intel LGA 2011-v3 processors (Haswell-E/Broadwell-E), featuring the X99 chipset, eight DIMM slots supporting quad-channel DDR4 3333MHz+ (OC) up to 128GB, and 5-Way Optimization for one-click overclocking. Main characteristics include the patented OC Socket for enhanced stability, 4-pin RGB Aura lighting, 32Gbps M.2 and U.2 storage slots, and reinforced SafeSlot PCIe slots (four x16, two x1). Pros are extensive connectivity with native USB 3.1 Type-A/C, Crystal Sound 3 audio, and a robust 8-phase digital power design. Cons are the lack of onboard Wi-Fi, no dedicated CMOS clear button on the rear I/O, and a somewhat limited 3-way GPU configuration compared to higher-end models.
