    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.
