ThunderboltEX 4 with Intel® Thunderbolt™ 4 JHL 8540 Controller, 2 USB Type-C Ports, up to 40Gb/s bi-Directional Bandwidth, DisplayPort 1.4 Support, up to 100W Quick Charge, Black

Works great if you hook it up correctly! Using an ZikeDrive Model Z666 USB4 M.2 Nmve case (they claim the fastest M.2 Drive Case): and an Fanxiang S880 4TB M.2 Nmve I get the fastest speeds of 3050.32 MB/s read, 2689.04 using Crystal Disk Mark 8 speed test. Running the Orico TCM-U4 Thunderbolt4 USB4 case with an Fanxiang S880 4TB M.2 I get the speeds: 3049.98 MB/s read, 2689.04 MB/s write. The Orico TCM-U4 is cheaper, but has a cooling problem with its top installed - but works great with thermal strip and copper heat sink and no top installed - it is reliable. But the ZikeDrive Model Z666 USB4 M.2 is slightly faster, has excellent cooling so far - better heat sink metal case with plastic over it - but the ZikeDrive is not as reliable when running thru my Plugable TB4 USB4 Hub (cant boot computer with it hooked in w/o error - sometimes errors if it is plugged in after computer booted? Seems to be working ok now.) The above ZikeDrive Model Z66 with Fanxian S880 4TB when plugged into Plugable TB4 USB4 Hub to Asus ThunderboltEx4 will get 2977.65 MB/s read, 1893.94 MB/s write for anyone who is interested. This same Fanxian S880 4TB when plugged into my Asus Hyper M.2 X16 Gen 4 Card or my Asus X670E-E motherboard M.2 PCIe 5.0 slot runs at 7271.24 MB/s read, 6187.19 MB/s write. So you can see the bottle neck is not in the M.2 I am using. It is cable of this speed, but Thunderbol 3 or 4 or USB4 is not cable of that speed. (I can't wait for Thunderbolt 5! I hope it works with my motherboard!) I am running Windows 10 & Windows 11 dual boot. Tests were done in Windows 10 on a Asus X670E-E Motherboard with AMD Ryzen 7950X3D CPU and using the GPU: MSI Gaming GeForce RTX 3060 Ti 8GB OC Edition "BGB GDDRR6X". And 96 GB DDR5 RAM (GSkill) 5400Mhz. So this is a top notch AMD computer build and is quite fast. I boot from an XPG 4TB GAMMIX S70 Blade PCIe Gen4 M.2 2280 Internal Gaming SSD Up to 7,400 MB/s in the PCIe 4.0 internal M.2 slot on the Asus Motherboard. (It has 3 PCIe 5.0 M.2 slots too reserved for future Raid-0 for video recording/editing and audio, etc.) To get this to work properly you MUST plug it into the proper PCIe X4 slot, plug the included cable from the USB 2.0 port on it into the USB 2.0 header on your motherboard, and plug the included cable from Thunderbolt Header on it into the Thunderbolt Header on your motherboard. If you don't hook it up to the USB 2.0, USB Devices can work on it, but no Thunderbolt. I have an Orico TCM-U4 Thunderbolt4 USB4 case with an Fanxiang S880 4TB M.2 in it, it was running at 1063.91 MB/s read, 1057 MB/s write, when the ThunderboltEx4 was not hooked up from its USB 2.0 to the USB 2.0 header on the motherboard. But when the ThunboltEx4 was hooked up correctly (USB 2.0 on it to USB 2.0 header on motherboard) then it was running at 3049.98 MB/s read, 2689.04 MB/s write, using the Fanxiang S880 4TB M.2.

After installing the card, connecting the TB/USB headers (opted to skip the PCIe as I don't need the PD functionality), and enabling TB4/USB4 (under AMD BPS for X670E BIOS), and downloading the TB manager from Asus' site it works exactly as expected. I can now swap my mouse/keyboard, 10Gig ethernet, and monitor (3440x1440p 175hz HDR) between my windows and macs with a single cable. The fit on the thunderbolt ports seems to be very loose, bumping the cable at all seems to result in a disconnect. There are also some quirks with Windows, sometimes it won't display HDR at 175hz at my native res (it will always do so if I drop to 144hz), and it doesn't seem to want to reconnect to the OWC Thunderbolt Pro Dock if I unplug and reseat the cable without powering the Windows machine off. (This may have been a Windows 10 issue, it now lets me disconnect/reconnect without power cycling just fine on Windows 11) At the end of the day, this has greatly simplified my current desk setup and I'll definitely be buying a motherboard with included Thunderbolt next time I'm in the market for an upgrade.

Hardware is fine (though misleading), support documentation is probably the worst headache I've dealt with coming from an established company such as Asus. I purchased this card to use with my standing desk setup - I wanted to clean up the cables a bit, and the best solution for me was to install a thunderbolt card. Having an Asus motherboard that properly supports this device, I bit the bullet and invested a couple hundred dollars in an entire thunderbolt setup. After countless hours troubleshooting the card (and researching online forums about trouble with this card in particular), I figured out why it's been so difficult to get it the way I wanted it to work: - Port 1 is a full-fledged thunderbolt port, meaning you get high-speed USB, PCIe tunneling, and all of that. Problem is, it seems to be a PURELY hot-swappable thunderbolt port, with the intentional design being that it does NOT work at all during boot (displays are a hit or miss), and that you can only use USB devices after the OS has loaded and the thunderbolt drivers are initialized. Every boot with peripherals connected to this port will throw a "No keyboard detected" bios error at you. - Port 2 is.. another thunderbolt port, which DOES work immediately during boot (all USB devices are accessible and displays have never failed me), but it does not have full thunderbolt capabilities - biggest issue being that it does not support anything above USB 2.0; I have no idea if PCIe tunneling works because quite honestly, it's discouraging to troubleshoot more after dealing with this garbage. This has been a HUGE inconvenience, because I have a Focusrite audio interface that requires a USB 3.0 connection to be stable - Considering that port 2 is the only usable port during boot (sure, power cycling the thunderbolt dock / hub works after boot, but this is not preferable at all - ESPECIALLY when most of the time, displays aren't usable until OS is running meaning you can't even access the BIOS), I'd have to power cycle the interface once every ~5-15 minutes, which sucks just as much. Worst of all? No manual for this device mentions this at all. The only reason I could come to this conclusion is through all those hours of research on forums for this device - every single negative comment I've seen have had the exact same issues that I've had, being that you'd have to power cycle the thunderbolt dock to make it work after a cold boot (on port 1, which is usually not mentioned but understandably feels like "the port" to have everything connected to), but nothing about port 2 being limited to USB 2.0 (I only found that out by checking USBView with that Focusrite interface connected to the dock by swapping it between the TB card's port 1 and 2; port 1 read that it was "SuperSpeed capable" [USB 3.0], port 2 read it was just "High-speed" [USB 2.0])

Al inicio me dio problemas, no reconocía lo que conectaba. Marcaba mensaje de que no estaba activado el tunel de pcie o algo parecido. Le actualicé el firmware, actualicé el bios de mi placa (ROG STRIX Z690-E GAMING WIFI), reinstalé windows 11 y nada. Luego de tanto buscar y toparme con varios usuarios con problemas similares, vi que uno dijo que lo cambió de slot y funcionó. Así que lo cambié a otro slot y ya funciona bien. Lo tenía conectado en el último slot, lo pasé al penúltimo y funcionó. Ahora trabaja de maravilla. Tengo un hub que tiene dos M.2 dentro (uno SATA y otro PCIe) y logra transferencias de 500 - 550 MB/s para el SATA y de unos 1.5 - 2.0 GB/s para el PCIe.

Great for a thunderbolt studio setup. Be sure to check your motherboard manual to see if this will actually work (some only support the USB-4 version which is not this product). Tested with a UAD x16 & AVID MTRX

USB2 のピンヘッダーを使用するので、マザーによってはピンヘッダーが枯渇します。 私の場合はピンヘッダーを増設して切り抜けました。

I use a Mac Pro for work but also game on PC so this allowed me to use all my peripherals like mouse, keyboard, monitor usb hub, headphone stand and sound card all be swapped between the two machines with a single cable. Before this I was using a usb 10GB hub which didn’t have enough bandwidth for all devices so was unplugging 7 cables from pc to Mac whenever I wanted to swap systems. I can even use my 5K Thunderbolt Display on my PC with this add in card. Just be sure to get the right version for your chipset. Mine is Z590 but I believe earlier chipsets use the thunderboltex tr but don’t quote me.
