    ThunderboltEX 3 Expansion Card is rated 3.1 out of 5 by 7.
    Rated 5 out of 5 by from Worked great! Worked completely as described on my Asus X99 II. Used the bottom most slot and then had to enable Thunderbolt in the BIOS and tell it what slot it was in. That's it. These steps weren't in the manual so hopefully this makes it clear what others should do.

    Rated 4 out of 5 by from Not Plug and Play, But It Works! I installed this on my Asus Maximus VIII Hero Motherboard. While the instructions say it's plug and play, it's definitely not. I watched this video and followed the instructions and it worked like a charm! I wish Asus did a better job presenting how to install it, but overall I was able to get it to work! I currently use this for my audio interface for music recording.

    Rated 1 out of 5 by from Waste of Money So I got the card installed, updated drivers, bios and all that only to find that the USB passthrough doesn't work and I can only send displayport signal. I contacted Asus support and they told me that because I bought the card in USA and not in Australia (you can't buy it here) that I would have to send it to USA for them to fix, So waste more money than the card is worth just for them to look at it. Yet to find anyone on the internet that has got the card working. If only you could give this product 0 stars, this is the last Asus product i'll ever buy.

    Rated 1 out of 5 by from Buy it if you want to waste your money (and time!) I recently bought this card to use on my brand new PC that I built myself. I made sure it was supported by my Asus motherboard but after installing drivers first and card later there is no way that the motherboard can see it! I updated the bios, got in touch with Asus support which is almost non-existent and after installing and re-installing windows 10, there is no way I can use this card. In short, this was not a smart purchase. Waste your time and money if can afford it.

    Rated 5 out of 5 by from Works exactly how it should Not sure how this product is getting all the negative reviews, but I have zero issues with this card. Super simple installation up and running within 10 minutes. Install the card, setup the bios to turn on Thunderbolt and specify the correct PCIe slot and youre running.

    Rated 5 out of 5 by from Awesome expansion card to add TB3 to my X299 PC! =] I bought this ASUS ThunderboltEX 3 Expansion Card to add Thunderbolt 3 ports to my Asus TUF Mark II X299 motherboard. It was fairly easy to install, especially since I referenced to the manual of the motherboard that revealed which PCIe slot to use and where the Thunderbolt header was. Summary: - This provides 1 Thunderbolt output via DisplayPort 1.2 with 10Gbps transfer speed, 1 USB 3.1 Type-A port with 10Gbps transfer speed, and 1 USB 3.1 Type-C port with 40Gb/s (5GB/sec) of data transfer speed. - The charging feature provides up to 36W of power! - You can achieve up to ! - It uses the PCIe 3x4 interface. - You can daisy-chain up to 6 Thunderbolt-equipped devices from a single Thunderbolt 3 port. - After physically installing this device, you can enable Thunderbolt on compatible motherboards via the BIOS. Some people commented it on being difficult to install, but I honestly had an easy time installing it! Youtube should fill in the blanks! I recommend this! =]

    Is Thunderbolt 3 backwards compatible with Thunderbolt Gen1 cables? I don't care about the USB 3.1 stuff that Google shares. I have older drives I need to keep using. If it is not, then what do I need to make it work?
    Asked by: Jordan M.
    According to the Specs, Yes. We don't have it working though. Thunderbolt 3 is excellent! Thunderbolt 2, not so much. On Thunderbolt 2 using an adapter, we can see the Device but we cannot see what's In the Device. We're using the Titan Ridge Thunderbolt 3 AIC on X299 & X399 Chipsets of specific Motherboards. Hope that helps!

    This came with my X99 Deluxe II motherboard, and I am struggling to get it to work with an Akitio Thunder 3 array. Have a Samsung 950 Pro M.2 NVMe drive installed, and just one AMD Firepro 4100 in slot 1. Can not see the array with USB 3.1 or Thunderbolt 3. But, the motherboard's built in 3.1 sees it perfectly! Any advice?
    Asked by: Brett
    Need to see the Motherboard. Cannot locate Pic of such. Not in PDF Manual ether. Requirements 1.) PCI Express 3.0 x4 (compatible with PCI Express x16/x8/x4 slots) - Use last PCIe Slot meeting those requirements. 2.) GPIO Header - Presence unknown. (For TB Header Cable). Some Users claim to have these working without. Don't know from experience. Our experience is from X399 & Titan Ridge Thunderbolt 3 Controller. Check Your Bios. Can You change the Bios Thunderbolt Setting to reflect what Slot you are using? In Bios - probably under Advanced tab, CPU Storage Configuration. No Bios Support? You may need this info later... TB Header Cable Pinout - 1. Gnd (Black) 2. Platform Sequence Control (Brown) 3. Platform Sequence Control (Red) 4. Plug_Event (Orange) 5. Power (yellow) Hope this little bit helps!

    Is there any reason this card wouldn't work with a 2010 or 2012 Mac Pro? Maybe the power consumption is too much? I'm worried that it might fry something on the motherboard. Thanks!
    Asked by: Anonymous
    The card needs a suitable PCIe 3 x16 slot plus a suitable video infeed plus a connection to a thunderbolt header. The latter is found only on some ASUS motherboards.
