Cool to the core
Power delivery enhancements and dual ProCool connectors
With up to 18 cores, four memory channels, and 44 PCIe lanes, the latest Intel® Core™ 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.
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.
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.

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.
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.
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.
