Expand Your Capabilities Effortlessly

We get that you love your marvelously slender Mac or PC, but also understand you often wish it offered more functionality. Now with the OWC Mercury Helios 5S, you can give your notebook, small form factor, or "all in one" desktop machine pro grade, full-size workstation capabilities. Whether you want to use an ultra-fast storage, 8K video capture, audio DSP, or high-speed networking PCIe card, Mercury Helios 5S makes it easy via a single Thunderbolt or USB4 connection and with no tools required. Plus, with three additional Thunderbolt 5 ports, it also gives you a handy next-gen connectivity hub. Embodying the heritage of innovation that has made OWC the global leader in Thunderbolt solutions, Mercury Helios 5S expands your capabilities effortlessly so you can think outside the traditional bulky desktop box when it comes to PCIe-based workflows.

• Internal Class Speed: Up to 6000MB/s bandwidth available for simultaneous read/write
• Widely Compatible: Use with Thunderbolt 5/4, USB4 Macs and PCs, and Thunderbolt 3 Macs
• Expands Small Machines: Use video capture, high-speed fiber/Ethernet, NVMe RAID, audio I/O, and other cards to unlock the potential of MacBooks, Mac Studio, Mac mini, and other space-constrained computers lacking a PCIe slot
• Whisper Quiet: Aircraft grade aluminum housing with high-efficiency, adjustable speed cooling fan provides cool, nearly silent operation
• Pro Level Card Ready: (1) PCIe 4.0 x4 (x16 mechanical slot) for half-length, full-height, single or double-width (including those with daughter board) cards
• Easy Card Installs: Captive thumb screws so no tools required
• Expanded Connectivity: Three Thunderbolt 5 (USB-C) 80Gb/s ports each with 15W power delivery for more device, display, and drive possibilities
• Complete, Secure, and Convenient: Includes Thunderbolt 5 80Gb/s cable, power cord retainer, and auto power on/off with your computer

Full-Speed PCIe Performance Ahead

Forget the belief that internal is always faster than external. The Mercury Helios 5S delivers up to 6000MB/s of bandwidth so you can run modern PCIe 4.0 cards at full speed while still accommodating data-hungry external Thunderbolt drives. Whether you're editing multi-cam 8K footage, running real-time audio processing, or transferring terabytes across a 25GbE network card, Mercury Helios 5S gives you the performance you'd expect from an internal PCIe slot with the flexibility of an external one.
