ASUS Prime X299-Deluxe Motherboard Review

The ASUS Prime X299-Deluxe ships in typical packaging that is built around a black box with plenty of information displayed.

An extremely healthy bundle is one of the key selling points for a premium motherboard. ASUS does not disappoint in this respect, equipping the X299-Deluxe with:

  • 6x SATA cables
  • 1x rigid 3-way SLI bridge
  • 1x rigid 2-way HB SLI bridge
  • Q-connector
  • Vertical M.2 mounting bracket and screws
  • RGB header extension cable
  • Rear IO shield

Adding to the core bundle is ASUS’ fan extension card. This molex-powered board is connected to the motherboard using a single cable and allows an extra three 4-pin fans to be connected and managed via software and the UEFI.

There are also connection points for the three included thermistor cables.

WiFi connectivity for the 802.11ac and 802.11ad interfaces is handled by two separate antennas. The plastic antennas are physically large and connect to points on the motherboard’s rear IO. Their cable allows them to be positioned optimally, rather than the aerials being fed directly out of the motherboard.

ASUS also includes the company’s ThunderboltEX 3 card to provide the X299-Deluxe with Thunderbolt 3 connectivity over the Type-C connector, in addition to an additional USB 3.1 Type-A port and Mini DisplayPort in (with an adapter cable) for loop-back capability from a graphics card.

Intel’s Alpine Ridge chipset is used an power delivery is rated at 3A over the 5V (15W) or 12V (36W) rails.

The usual set of documentation is provided, in addition to a 20% discount code for CableMod cables.

    Awesome review…..but my heart leapt when I saw the Air 540, I still mourn the day I sold it, I can still see it leaving my street in the back of the guys car. Goodbye little ‘Sugercube’ I still miss you.
    PCIE slot placement has always been a thing for ASUS or at least on every board I’ve ever owned, I remember not being able to SLI because a gpu fouled all of the headers on the bottom of the mobo a few years back. Did you try the 5 way optimisation ; ) I’m just curious knowing how generous it can be with voltages, you will get some customers who click it and just trust it knows what its doing.

    “Positioned close to the 24-pin is one of the board’s two M.2 connectors. This PCIe 3.0 x4-only slot is mounted to allow for vertical orientation of an installed M.2 device. A support bracket and screws are included. Vertical mounting is good for putting the device in a direct airflow path, while also minimising the footprint taken up on the board PCB”. – Yup and is all the worst way to put one and will get snapped by any wandering hands of if some one mounts a DVD rom’s that are to log for the slot (yes ppl still use DVD roms).
