If you\u2019ve ever wished your MacBook, Mac mini, or Mac Studio had \u201cjust one PCIe slot,\u201d the new OWC Mercury Helios 5S<\/a> is here to grant your wish. <\/p>\n\n\n\n

It\u2019s a Thunderbolt 5 PCIe expansion chassis that lets you run a full-size workstation-class PCIe card over a single cable\u2014then goes a step further by giving you three Thunderbolt 5 ports for more devices and displays. <\/p>\n\n\n\n

In other words: with one simple connection, you gain pro-card capability and you grow your I\/O at the same time. Mercury Helios 5S<\/a> is the ultimate Mac expansion solution.<\/p>\n\n\n\n

Which Mac users is Helios 5S for?<\/strong><\/h2>\n\n\n\n

Modern Macs like the Mac Studio, Mac mini, MacBook Pro and even the iMac are crazy fast, whisper-quiet, and wonderfully compact\u2014but internal PCIe slots didn\u2019t make the cut for obvious reasons.<\/p>\n\n\n\n

For Mac creators and power users who need speciality cards, Helios 5S<\/a> fills that gap by providing a quick way to tap into video capture\/IO, high-speed Ethernet or fiber, NVMe RAID, pro audio DSP, and more.\u00a0<\/p>\n\n\n\n

Plug Helios 5S into a Thunderbolt 5\/4\/USB4 Mac (or even a Thunderbolt 3 Mac) and you\u2019ve effectively added a PCIe bay without cracking the case.<\/p>\n\n\n\n

Cards install in seconds<\/h2>\n\n\n\n

To get going with Helios 5S, you don’t have to be an IT professional thanks to this enclosure’s tool-free design. Helios 5S is compatible with half-length, full-height, single- or double-width pro-level PCIe cards from leading brands like AJA, Apogee, ATTO, AudioScience, Avid Pro Tools, Blackmagic Design, Intel, RME Audio, Solid State Logic, Universal Audio, and OWC. <\/p>\n\n\n\n

And you can install a card in seconds:<\/p>\n\n\n\n

  1. Disconnect the Thunderbolt cable and power cord from Mercury Helios 5S<\/li>
  2. Loosen the two captive thumb screws and<\/li>
  3. Reconnect the Thunderbolt cable and power cord to Mercury Helios 5S<\/li><\/ol>\n\n\n\n
