OWC Thunderbolt 4 hub on a desk

Dear PC, We Have Arrived. Sincerely, The OWC Thunderbolt 4 Hub.

For the first time ever, OWC’s Thunderbolt Hub gives you the additional Thunderbolt ports you’ve wanted. Connect more, display more, and charge more with this new Thunderbolt 4 solution.

The OWC Thunderbolt Hub expands the number of Thunderbolt ports available on your Thunderbolt 4 PC. Through a single Thunderbolt 4 port, you can connect and charge nearly anything with this compact hub. Dual 4K displays (or a single 5K, 6K, or 8K display), high-performance storage (including NVMe solutions), A/V mixers, phones and tablets, even desktop accessories like a keyboard or mouse are all fair game. Accessories with past, present, or future USB or Thunderbolt interfaces…all connect to the OWC Thunderbolt Hub.


  • All the Thunderbolt you’ve always wanted: For the first time ever, add more full speed, fully functional Thunderbolt ports to your computer
  • Plug everything in:  Same device compatibility and performance, whether plugged into the hub or directly into your machine   
  • Manage more devices:  Connect storage, two 4K displays or one 5K/6K/8K display, multiple accessories you name it, you can use it
  • Revolutionary development: New multi-port accessory architecture reinvents the daisy chain and allows more bus-powered devices
  • Powerful capabilities: Thunderbolt 4 host port keeps notebooks powered and charged
  • Adjustable LED: Customize illumination for your unique work setting
  • Built-in security: Kensington Nano Security Slot™ for anti-theft cabling
  • OWC ClingOn™ ready: Cable stabilizer prevents work session interruption and data loss
  • Independently tested and Intel Thunderbolt-certified for Windows

“As a leader in Thunderbolt integration and accessories, OWC is proud to lead the market and offer our first Thunderbolt 4 hub for the new 11th Gen Intel® Core™ processor-based PCs.,” said Larry O’Connor, CEO and Founder of OWC. “In addition to giving users the ability to expand the number of Thunderbolt ports they have access to, the new ability to create separate chains, and connect more devices from individual computer ports will revolutionize workflows.”

Daisy Chain Away

Daisy chains can be complex. In the past, removing any device besides the last one in a daisy chain caused a disruption that rendered all devices unusable until the chain was re-established. OWC’s Thunderbolt Hub lets you create a separate multi-port accessory architecture consisting of three “tree branch” chains, so you can remove devices from one chain without affecting or disconnecting the others. Now you can connect multiple portable SSDs directly to the OWC Thunderbolt Hub to experience the fastest speed your storage device can deliver.

Pricing & Availability

The OWC Thunderbolt Hub is available for pre-order through MacSales.com for $149.00 and will begin shipping in late October.

  • This site is called MacSales yet you say this hub is for Windows? And please stop putting ports on the front of hubs… keeping all cables routed toward the rear makes for a cleaner desktop. Those who need access on the front can simply route that cable as needed.

    • Though the largest portion of OWC’s customer base is Apple users, we don’t ignore the PC crowd. :-)

      In fact, many of our products work with both Apple and PC hardware.

      • Out of curiosity, how does this hub behave when connected to a Thunderbolt 3 Mac? Or a Thunderbolt 3 PC? Does at least one of the downstream Thunderbolt 4 ports work for Thunderbolt 3 chaining? Do the other downstream Thunderbolt 4 ports at least allow connecting USB devices? Or DisplayPort devices (up to two?) – it would be a nice way to have two display capable USB-C ports – then the third port could be for Thunderbolt chaining – in this way Thunderbolt 3 compatibility could be possible – it would depend on the drivers.

        If there are problems with drivers in macOS Catalina 10.15.7 then perhaps Big Sur 11 will have improvements?

        You’ve already said “At this time we are only able to confirm Thunderbolt compatibility with Thunderbolt 4 equipped PCs running Windows.” So I guess we have to wait for a reviewer to try it?

        • All great questions! I’m glad that you understand that we are limited in what we can say. And though we can’t speak to specifics right now, we anticipate that a lot of these questions will be answered when Big Sur is released.

  • Was this tested with any 6K displays? What GPU? The only one I know of is the Apple Pro Display XDR. It supports two connection modes for 6K: dual HBR3 and single HBR2 with DSC.

    You say the Thunderbolt 4 hub can connect a single 6K display, but I believe every Thunderbolt 3 device does not allow connection of an XDR when using dual HBR3 mode (even the Thunderbolt 3 optical cables have this problem). For a dual HBR3 connection, the XDR must be connected directly to a Mac or Blackmagic eGPU to get 6K with no Thunderbolt dock in-between the XDR and the Mac. Actually, this Thunderbolt 4 hub is only for PCs, and I don’t think any PC’s have a Thunderbolt 3 controller + driver supporting dual HBR3 connection. Do PC’s with Thunderbolt 4 controllers have the ability to send dual HBR3 to the XDR?

    With a GPU that supports DSC, you should be able to connect two XDR displays since only HBR2 with DSC is required for each display.

    For 5K, you are referring to displays that use dual HBR2 like the LG UltraFine 5K. There also exists 5K displays that use single HBR3. In either case, only one 5K display can be connected. Maybe in the future there will be 5K displays that use HBR2 with DSC. In that case two could be connected.

    For 8K, you are referring to displays that use a single HBR3 with DSC signal for 60Hz or 30Hz without DSC. Dual HBR3 for 60Hz for the Dell UP3218K is impossible over Thunderbolt 3/4.

    However, there exist DisplayPort 1.4 MST hubs that support DSC. They can decompress DSC for displays that don’t use DSC. With this capability, you could send a single HBR3 with DSC MST signal to a dual HBR2 display such as the Dell UP2715K to achieve 5K 60Hz. If it were an HBR2 with DSC signal (which is possible since 6K only requires HBR2 with DSC), then perhaps two MST hubs could be connected to a Thunderbolt 3/4 hub/dock to support two 5K displays. I don’t know if a single HBR3 with DSC MST signal to a dual HBR3 display such as the Dell UP3218K to achieve 8K 60Hz is possible.

    Conversion from dual DisplayPort back to Thunderbolt 3 to connect a Thunderbolt 5K display like the LG UltraFine 5K currently requires a Thunderbolt 3 add-in card. Maybe in the future a USB4 hub can do that (since Intel probably won’t allow it with Thunderbolt devices except the Blackmagic eGPU which did it internally).

    • PCs with Thunderbolt 4 today are all TigerLake chipset based and the integrated graphics with these systems support up to an 8K display and said displays can be connected without issue via/through our Thunderbolt Hub.

      No additional add-on card should be required, but we would defer to Dell or Apple for specific requirements they may have with respect to using these displays.

      And you are correct… TB4 is up to 2 x 4K or 1 x 5K/6K/8K.

      • Oh, right. In the case of Tiger Lake, I would expect Integrated Graphics to be the DisplayPort source of the integrated Thunderbolt 4 controller. Integrated Graphics supports DSC (like Ice Lake) so only one DisplayPort connection is required for 6K, but there may be limits on the number of pixels the Integrated Graphics can support which may explain why only one 6K display is allowed even though Tiger Lake can support 4 displays.

        However, in the future, there could be PCs that use discrete Thunderbolt 4 controllers (the JHL8440 in host mode). In that case what I described previously may be possible: for one, a more powerful GPU as the DisplayPort source should allow two 6K displays when using DSC.

        Basically, you are describing the capabilities of the Thunderbolt 4 hub based on connection to a Tiger Lake Thunderbolt 4 controller instead of describing the max capabilities of the hub.

  • Is it compatible with current Macs with Thunderbolt 3 and peripherals? Will it be compatible with future Macs with Thunderbolt 4 and peripherals?

    • Our official statement on this is “At this time we are only able to confirm Thunderbolt compatibility with Thunderbolt 4 equipped PCs running Windows.”

      • Mark, what’s with playing footsie. Is this compatible with a Mac or not? It works, but you don’t guarantee it? I defiantly need this type of hub for my IMac. Not enough Thunderbolt ports!

        • Given that there are hints in previous replies that indicate that OWC is waiting for macOS Big Sur to be out, I suspect that support will be available with that OS.
