OWC Mercury Helios 5S | Thunderbolt 5 PCIe Expansion

Unlock Workstation-Level Power with the NEW OWC Mercury Helios 5S — Thunderbolt™ 5 PCIe Expansion Solution

Introducing the OWC Mercury Helios 5S, the ultimate Thunderbolt 5 PCIe expansion chassis designed to bring full-size workstation performance to MacBook Pro, Mac Studio, Mac mini, Thunderbolt 4/USB4 PCs, and any compact setup that lacks internal PCIe slots. If you’ve ever wished your portable or small-form-factor computer could handle 8K video capture, high-speed NVMe RAID, fiber/Ethernet networking, or pro-audio DSP, the Helios 5S delivers all of it — with internal-class performance up to 6000MB/s.

The Mercury Helios 5S features a PCIe 4.0 x4 (x16 mechanical) slot, supporting half-length, full-height, single or double-width cards. Built from aircraft-grade aluminum with a precision heat sink and high-efficiency cooling fan, it runs whisper-quiet, even under heavy creative or professional workloads.

And that’s just the beginning. With three Thunderbolt™ 5 (USB-C) 80Gb/s ports with 15W power delivery, the Helios 5S doubles as a powerful connectivity hub, expanding your workstation with additional drives, displays, and specialized devices. It includes an 80Gb/s Thunderbolt 5 cable and a power-cord retainer for a secure, professional setup—backed by OWC’s trusted 3-year limited warranty.

Whether you’re a filmmaker working with massive RAW files, a photographer juggling multi-terabyte shoots, a live streamer, audio engineer, 3D artist, or IT professional, the Mercury Helios 5S unlocks the PCIe performance your workflow demands.
