ASUS Prime X299-Deluxe II is the ATX motherboard that's been expertly engineered for professional content creators and power users who work hard by day and play harder by night. This powerful, innovative board puts a friendly face on advanced enthusiast controls, enabling you to maximize performance, cooling and personalization with ease. So, if you live to create, to explore, to enjoy and to push the boundaries, look no further than Prime X299-Deluxe II.

Power delivery enhancements and dual ProCool connectors
With up to 18 cores, four memory channels, and 44 PCIe lanes, the latest Intel Core™ processors demand a lot more juice than typical desktop CPUs. Prime X299-Deluxe II feeds their appetite with 12 power phases hooked up to the socket and two more for the DRAM. It also augments the motherboard's link to the PSU with dual eight-pin connectors that pass 12V power directly to the processor. These jacks are based on our ProCool design, which uses solid pins that can handle more current than conventional connectors with hollow pins.

VRM design
Higher power requirements are balanced by beefier heatsinks that carefully balance mass and surface area to maximize thermal dissipation. With a VRM-heatsink array and heatpipe positioned in the path of maximum airflow within the chassis, Prime X299-Deluxe II ensures optimal cooling and system stability for the latest Intel Core X-series processors.

M.2 Cooling
Keep your SSD chilled
Two M.2 slots sit under passive heatsinks to ward off the throttling that can occur with sustained transfers. A third pokes out from the PCB vertically near the memory slots, where connected drives benefit from ambient airflow around the CPU socket.

Fan Extension Card II
Prime X299-Deluxe II includes our new Fan Extension Card II, which adds six headers that are controllable via FanXpert 4. The card has three temperature-sensor headers to complement the one available onboard and, more importantly, it comes with three thermistors that you can affix to different components. In addition to supplying extra headers for cooling, it has three primed for RGB LED strips.

5-Way Optimization
One-click overclock and cooling, done!
One click takes care of all that complex tuning. ASUS 5-Way Optimization makes your PC smart. It dynamically optimizes essential aspects of the system, providing overclocking and cooling profiles that are tailored for your rig.

- An automated tuning utility that optimizes overclocking and cooling profiles for your unique system configuration.
- Fans stay whisper-quiet for everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks.
- All-new stress test that allows users to optimize and overclock for CPU or memory-centric workloads.

Media-acclaimed UEFI BIOS
The UEFI BIOS is an early waypoint on any PC-building journey, and Prime X299-Deluxe II offers one of the best in the business.

OC design- ASUS PRO Clock II technology
Prime X299-Deluxe II includes a dedicated base-clock (BCLK) generator that extends CPU and memory overclocking margins. This custom solution works in tandem with the TPU to enhance voltage and BCLK overclocking control, providing the flexibility to extract every ounce of performance from the latest Intel Core X-series processors.

Make your memory go faster
With optimized trace paths for time-aligned signaling and minimal crosstalk, third-generation ASUS T-Topology offers enhanced memory stability and compatibility, allowing support for DDR4 memory speeds of 4266MHz and beyond.

Multi-GPU support
Fully loaded takes on new meaning when you have up to 44 PCI Express lanes stemming from the CPU. Those lanes can be split in an x16/x16/x8 configuration spanning the board's trio of PCIe x16 slots, allowing you to load up on GPUs to accelerate an increasingly diverse array of workloads that include 3D rendering, scientific research, financial modeling, and AI training.

SafeSlot
Protect your Graphics Card Investment
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process, SafeSlot integrates the slot with fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.

VROC
Upgrade your RAID
The PCIe slots can be used to connect bootable RAID arrays directly to the CPU via Intel's VROC technology and a special key that plugs into the motherboard. With our Hyper M.2 x16 Card V2* installed, Prime X299-Deluxe II is able to host up to four NVMe SSDs on a single x16 card with integrated cooling. Factor in the ability to add an onboard SSD and that's access to a lot of ultra-fast storage, plus VROC supports arrays that span multiple cards for even higher speeds and capacities.
* ASUS Hyper M.2 x16 Card V2 is a separate purchase.
** A VROC key is required to enable VROC RAID arrays. For information about VROC key availability, please contact your local Intel representative.

M.2
Achieve speed with onboard M.2
With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It's the perfect choice for an operating system or application drive, providing fast access to data. And all three slots support longer 110mm M.2 drives with more room for flash storage than shorter 80mm sticks.

Intel Optane™ memory
Intel Optane memory ready
Intel Optane™ is a revolutionary non-volatile memory technology supported by Prime X299-Deluxe II. Intel Optane memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.

Thunderbolt™ 3 port
Experience blistering Thunderbolt 3 speeds and any-way-up connectivity
High-speed external storage is required for many workstations, so Prime X299-Deluxe II integrates Thunderbolt 3 with up to 40Gbps of aggregate interface bandwidth. The rear I/O panel has dual Thunderbolt 3 Type-C ports that support data in addition to DisplayPort 1.4 output. Up to six devices can be daisy-chained from one Thunderbolt 3 port, with the provision of up to 15W of power for fast-charging devices connected in this way.

USB 3.1 Gen 2 front-panel connector
Future-proof connectivity
Prime X299-Deluxe II's front panel USB 3.1 connector is ready for next-gen PC cases and devices.
