General Features

Cool to the Core

Power Delivery Enhancements and Dual ProCool Connectors
With up to 18 cores, four memory channels, and 44 PCIe lanes, the Intel Core processors demand a lot more juice than typical desktop CPUs. The 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 of power directly to the processor. These jacks are based on their 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, the Prime X299-Deluxe II ensures optimal cooling and system stability for the Intel Core X-series processors.
M.2 Cooling
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.
Cooler by Design
The Prime X299-Deluxe II features comprehensive cooling controls that are configurable via FanXpert 4 or the UEFI BIOS:

Multiple Temperature Sources
Each header can dynamically reference three thermal sensors, and via FanXpert 4 you can even map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

Water Pump+
A dedicated header that can supply over 3A to high-performance PWM or DC water pumps.

AIO Pump
A dedicated PWM/DC header for self-contained water-cooling setups.

4-Pin PWM/DC Fan
Every onboard header supports auto-detection of PWM or DC fans.

Bundled Fan Extension Card II
Includes six additional DC or PWM fan headers, plus three thermal-probe headers.

Smart Protection
A dedicated integrated circuit that protects each fan header from over-temperature and over-current.

Fan Extension Card II
The Prime X299-Deluxe II includes ASUS' 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.

Screw holes allow you to mount the card to a 2.5" bay on your chassis and the ASUS Node connector allows you to connect an additional compatible PSU or accessories.

User-Friendly Extras

Pre-Mounted I/O
Form meets function in the pre-mounted I/O shield ASUS pioneered with the ROG series. Now available on the Prime X299-Deluxe II, this feature streamlines the installation process for budding builders and savvy enthusiasts alike.
LiveDash OLED
The Prime X299-Deluxe II has a 2" LiveDash OLED dominating the center of the board. It's positioned for easy visibility and capable of showing vital system stats like clock speeds, temperatures, and voltages. For a more personalized touch, it's easy to add text and custom images, including animated GIFs.
ASUS Node
The ASUS Node connector offers a bidirectional interface with lots of potential for DIY components and builds. The included ASUS Fan Extension Card II connects via Node, while In Win is developing a compatible OLED panel that fits into a chassis and offers both LiveDash functionality and the ability to boot directly to the UEFI. FSP has also created the HydroDPM 1000W PSU that connects to Node to share power stats, temperatures, and enable control over the CPU fan.
Aura Sync
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs, as well as the LED strips connected to the onboard 4-pin RGB headers. It can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
Addressable RGB LED Strip Header
The Prime X299-Deluxe II now has a dedicated addressable RGB header, suitable for connecting to lighting strips, fans, and compatible PC cases. ASUS' Aura software contains an array of effects for addressable gear, and the Aura SDK takes things to the next level, allowing developers to control each LED individually - unleashing infinite lighting possibilities.
