Packaging and Accessories
The box for the Prime X299 Deluxe has the same basic black background of our X99 and X370 boards only the box for this one is noticeably larger than the others. On the front Asus has a large photo of the board with the model name next to it. Then down along the bottom is a list of the supported features like SLI, the various audio formats, and Asus Aura lighting. The front of the box also opens up and although the board is in a static protective bag you can kind of see it. The flipped up door also has more information on the back. It has a photo of the board with lines drawn to it pointing out some of the board's features with short descriptions and sometimes additional photos to go along with the descriptions. The back of the box is similar as well with another main photo along with a full specification list, then on the right more features on the board's many many features and accessories.
With the motherboard pulled out I found that more than half of the box is actually just filled with accessories. Right up on top, there were a few trays with a PCIe card and a few SLI bridges. Then under that, there was a lot of documentation. You get a full user guide for the board and an additional user guide for the ThunderboltEX 3 card. There is a small paper for the included fan extension PCB and a CableMod discount code to pick up some Asus Aura lighting. Then for discs, you get a driver/software disc and a second disc for the ThunderboltEX 3 card.
So the PCB that we saw when first digging into the box was the included ThunderboltEX 3 card. It is a short PCIe x1 slot device with a black PCB. It has a thunderbolt header in the top right corner, then on the outside facing slot, you get an additional USB 3.1 Type A, a USB 3.1 Type C with Thunderbolt 3, and a Mini DisplayPort In.
The X299 Deluxe came with another small breakout board. This is the fan extension PCB. It hooks to the motherboard down in the bottom right corner of the motherboard using the EXT Fan plug that is on the bottom left corner with the white header. Basically, this breakout board lets you add four more four pin fan headers. To power it though you will also need to plug in that four pin Molex.This board also has the three headers for the includes thermal probes as well so if you plan on using them you will need to integrate this board into your build.
The included rear I/O shield has a white and gray stripe finish on it that almost looks a little strange. I personally would still prefer this to be solid black as that normally goes with more cases, but it does match the Prime look. The back has a foam padding to replace the metal springs but if you look you can see that one of the USB ports does still have the metal spring so you do have to be careful not to get that inside of the plug when installing the board. The Prime X299 Deluxe also comes with a high bandwidth PCB SLI bridge. Then for wireless antennas, they include two. One is for the new Wireless AD adapter and it has a black finished connection so you can spot it, then there is also the normal wireless AC antenna as well. They have a new longer shape but still have magnets inside so you can stick them right to your case if needed.
Digging through the huge pile of bags of accessories I found three bags with SATA cables, this gets you a total of 6 with three of those having a right angle on one end. The external fan breakout board cable was in the mix. There was also a mini-display port adapter and the Thunderbolt internal header cable as well. Then they included a 3 way SLI bridge that is blacked out and PCB as well should you be looking to go triple SLI for some reason. There was a pile of screws for the fan extension mounting and for the included vertical M.2 mount. There was also a Q-connecter that helps you plug in the front panel connections. Then I was really surprised to see three thermistor cables that you can hook to the board and attach to other items in your PC to keep track of additional thermals.
