Maximize your PCIe Card Investment
Using a video, audio, storage, network, or even gaming PCIe card with a Mac Pro or PC desktop is a simple matter of inserting your card into an open slot. But what do you do if you have a laptop or even a space-confined desktop like an iMac or Mac mini that doesn’t contain a PCIe slot?
The Mercury Helios 3S is an easy to use yet powerful expansion solution that adds an external PCIe slot to your Thunderbolt 3 equipped computer. Now you can maximize your existing PCIe card investment — or expand it! — while enjoying the flexibility of adding professional-class video production, transcoding, audio processing, data storage, and high-speed network connectivity to your machine.
Retask Without Limits
Instead of buying one or more function-dedicated Thunderbolt interface devices, you can use Mercury Helios 3S like a dock for multiple PCIe cards. Capture incredibly high-quality audio with a PCIe audio card and then retask Helios 3S with a PCIe SSD card to edit and archive tracks. You can swap cards in minutes, adding a new level of flexibility to your workflow.
Capture, Stream, and Share in Seconds
With dual 40Gb/s Thunderbolt 3 ports, the Mercury Helios 3S offers the bandwidth needed to support data-intensive 4K capture cards to speed up diverse video workflows such as vlogging. Boost your DAW with external DSP acceleration and run larger mixes with multiple plug-ins. Live stream the action in your gaming sessions or share files over a 10GbE or Fibre Channel network without any speed throttling.
Pro-Level Performance Cards for Every Need
Mercury Helios 3S supports a wide variety of half-length, full-height, single or double-width, pro-level PCIe cards from leading brands like AJA, Apogee, ATTO, Avid Pro Tools, Blackmagic Design, CalDigit, HighPoint, Intel, Solid State Logic, Universal Audio, and OWC.

Thunderbolt Made Easy
We make it easy to choose the right gear. Our Thunderbolt Certified products offer the same performance and functionality whether they are Thunderbolt 3 or Thunderbolt 4. And if you’re rocking a beloved Thunderbolt 2 machine, we offer an adapter so you can plug into our universe of award-winning solutions. No hassles, no confusion. That’s the OWC Difference.
Apple Mac models with Thunderbolt 2/Thunderbolt ports can be connected using an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt 2 cable (not included). This configuration provides data transfer at up to 20Gb/s but does not support notebook charging.
OWC Thunderbolt Cable Included
OWC Mercury Helios 3S comes with a certified OWC Thunderbolt Cable. But if your workflow demands a different length to make the connection, OWC Thunderbolt (USB-C) Cables are the perfect choice.
Work with Ultimate Confidence
Active workspaces expose gear to unexpected bumps and shoves. OWC ClingOn custom cable stabilizers (available separately) are the quick and easy way to reduce – if not completely eliminate – cable strain on Thunderbolt and USB-C connections so you can work with ultimate confidence even in the highest foot traffic environments.
