What we like about ASUS X99 Deluxe U3 1

  • Extremely rich feature set including built-in 3x3 802.11ac Wi-Fi and Bluetooth 4.0
  • Comprehensive accessory bundle including a Fan Extension card and Hyper M.2 x4 PCIe card
  • Excellent overclocking potential supported by the proprietary ASUS OC Socket
  • High-quality software suite (AI Suite 3) and an industry-leading, easy-to-use UEFI BIOS
  • Robust storage options with multiple M.2 slots, SATA Express, and up to 12 SATA 6Gb/s ports
  • Dual Intel Gigabit Ethernet ports which can be teamed for better performance
  • Distinctive and premium black-and-white aesthetic design

Verdict

The Asus X99-Deluxe/U3.1 is a premium ATX motherboard featuring the Intel X99 chipset and LGA 2011-v3 socket, supporting Haswell-E and Broadwell-E processors with up to 10 cores. It includes 8 DIMM slots for quad-channel DDR4 memory (up to 128GB at 3200MHz O.C.), five PCIe 3.0 x16 slots for 3-way SLI/CrossFireX configurations, and a comprehensive storage suite with 12 SATA 6Gb/s ports, dual M.2 x4 slots (onboard and via PCIe card), and dual SATA Express. Main pros include its patent-pending OC Socket for enhanced overclocking stability, integrated 3x3 802.11ac Wi-Fi, and a rich accessory bundle featuring a fan extension card and the namesake USB 3.1 Type-A expansion card. Some cons noted by users include high power consumption under load, potential lane-sharing limitations between PCIe and high-speed storage, and its significant initial investment cost.
