The ASUS X99 Deluxe U3.1 ATX Motherboard features an Intel LGA 2011-v3 socket to let you build a computer system using an Intel Core i7 processor. To keep up with the fast CPU, it supports up to 8 sticks of DDR4 memory modules that write and read faster as well as use less energy when compared to DDR3 RAM. For creating storage capacity, this motherboard has eight SATA 6 Gb/s connectors and can also accept storage drives with a SATA Express or a M.2 interface.

When equipped with a 40-lane processor, this motherboard provides five PCIe 3.0 x16 slots that can handle up to four graphics cards linked using SLI or CrossFireX technology. This motherboard allows the system to access a network wirelessly at a transfer rate up to 1300 Mb/s with 3x3 2.4/5 GHz antennas and 802.11ac. For a reliable and lag free network connection, it comes with dual Gigabit Ethernet ports that can be linked with teaming technology. The ATX form factor motherboard has 10 x USB 3.0 ports, 2 x USB 2.0 ports, 5 x audio jacks, and 1 x S/PDIF out port. In addition to the USB ports, ASUS includes a USB 3.1 PCIe card that provides two USB Type-A ports that transfer data up to 10 Gb/s.

Key Features

CPU and DDR4 Performance

  • The ASUS OC Socket is compatible with Haswell-E LGA 2011-v3 CPUs and utilises extra pins for connecting a proprietary circuit to Haswell-E's land grid array (LGA). Combined with a customised UEFI, this feature enables higher DDR4 memory frequencies, lower latencies, and enhanced stability when overclocking. This socket provides overclocking performance with the Haswell-E LGA 2011-v3 CPUs.

Cache Bus Voltage Adjustment

  • The cache bus links areas such as CPU cores, DDR4 memory controllers, System Agent, and the L3 cache. The ASUS OC Socket lets you adjust the cache bus voltage so the system can reach higher cache bus frequencies that provide faster sub-system performance.

Faster Memory Support

  • This motherboard supports DDR4 memory and memory frequencies up to 3200 MHz. With ASUS's T-Topolgy circuit design and OC Socket, the full power of DDR4 memory is unleashed by minimising coupling noise and signal reflection. Additionally, the RAM slots are positioned to deliver balanced control and overclocking compatibility. When compared to DDR3 RAM, DDR4 memory modules can deliver twice the write and read speeds as well as use 20% less power.

ASUS 5-Way Optimisation

  • The X99 motherboard dynamically optimises essential aspects of your system based on real-time use to provide CPU performance, everyday energy savings, ultra-stable digital power, and quiet fans. It even adjusts the networking and audio settings for the apps that you are using. In short, 5-Way Optimisation ensures that your PC is suitable for gaming, entertainment, productivity, or just about anything else.
  • Games run swiftly and smoothly with high performance, prioritised bandwidth, and clear sound
  • Fans stay whisper-quiet for everyday computing and ensure cooling efficiency when gaming
  • Helps prevent stutter when running professional apps and heavy loading
  • Energy waste is reduced so you'll save money

Turbo Processor Unit

  • Increase the system's performance by using the two-phase on-board switch or the AI Suite 3 utility software. The Turbo Processor Unit offers precise voltage control and advanced monitoring for the CPU and graphics card, enabling you to adjust CPU frequencies and ratios for optimised performance and exploit the potential out of your graphics card.

Energy Processing Unit

  • This processing unit automatically detects and adjusts the power consumption based upon the system's needs. It can reduce the CPU wattage to an indicated level or even provide more savings with Away Mode, which creates an extreme energy-saving scenario by shutting down unused extra I/O controllers and reduces the power level in graphics cards.

Fan Xpert 3

  • Fan Xpert 3 Fan puts the 4-pin/3-pin CPU and case fan controls in one place. It scans each fan's characteristics and delivers custom settings for each fan based on the dedicated area temperatures detected by hardware thermal sensors. This allows every fan to achieve the best balance of cooling performance and low noise. Fan Xpert 3 supports hardware-level PWM/DC combo mode for both the CPU and case fans. It even can reduce the CPU fan speed to below the default minimum, for extra-quiet and power saving operation during light loads.

DIGI+ Power Control

  • Power control is an essential motherboard design. ASUS DIGI+ Power Control fully complies with Intel's VRD12.5 specifications to increase overclocking potential, enhance system stability, and improve power efficiency with flexibility and accurate control.

Turbo App

  • Gamers and professionals can benefit with the ASUS Turbo App. It offers a tuning panel that boosts your hardware by overclocking your CPU, tuning your fans, prioritising network data, and optimising audio settings automatically.

Fan Extension Card

  • This card lets you connect up to three extra fans for a maximum of nine fans (including 2 CPU fans and 7 case fans). Each fan can be controlled independently from either the UEFI BIOS or AI Suite 3 by providing it with up to 12W. This helps you build a water cooled or extreme airflow high performance system.

3x3 (3T3R) 802.11ac Wi-Fi

  • This motherboard offers 802.11ac Wi-Fi and includes 3x3 dual-band 2.4/5 GHz antennas that can transfer data up to 1300 Mb/s.


  • The mouse-controlled graphical BIOS has been improved that lets a PC novice or seasoned overclocker to find controls and menus quickly and easily.

USB 3.1 Card

  • The included PCIe USB 3.1 Type A expansion card fits in any PCIe x8 or x16 slot to provide the system with two USB 3.1 ports. These ports transfer data at a rate up to 10 Gb/s and the ASUS USB 3.1 Boost utility software can provide even faster transfers.

Evolve Your Storage Speed with SATA Express

  • The two SATA Express ports provide up to 10 Gb/s transfer speeds utilising two PCIe 2.0 lanes. Some SSDs transfer data up to 550 MB/s, which is close to the saturation point for SATA 6 Gb/s connections. Backward compatible with up to two SATA drives, SATA Express ensures your system won't be left behind.

M.2 Slot

  • With a PCI Express 3.0/2.0 x4 bandwidth, M.2 supports up to 32 Gb/s data transfer speeds. When a M.2 drive is connected to the slot, the system runs faster when the operating system and software programme are installed on the drive.

Crystal Sound 2

  • Crystal Sound 2 optimises the audio settings when you're playing a game, chatting, watching movies, or listening to music. The motherboard is equipped with a physical shielding, Japanese-made audio capacitors, and operational amplifiers to provide sound clarity and fidelity.
  • Audio Shielding - ensures analogue/digital separation and reduces multilateral interference
  • EMI Protection - prevents electrical noise to affect the audio quality
  • Audio Amplifier - enhances the sound quality when using a headphone or speakers
