Does it support daisy chaining another Thunderbolt 3 device to the 2nd port? e.g. A 10gbe Thunderbolt network adapter.

Hello. Yes, the OWC Mercury Helios 3S will allow or thunderbolt device to be daisy-chained off the second port of this chassis.

Can you install a gpu card like nvidia into this?

Hello. No this unit does not support GPU's.

is this thunderbolt 4 compatible?

Hello. This Mercury Helios 3S is a Thunderbolt 3 device, but can be used in a Thunderbolt 4 port as 3 is backwards compatible.

Will this work with bootcamp windows 10/11 for a lynx aes16e interface card?

I bought this for my vive wireless pcie wigic card and just googled yours. From what I see so long as you have a thunderbolt 3 port it should work.vyour card should fit. However from the looks of the googled image you may have to keep the casing off. No loss it will still work just no shell.

Works with Avid HD Native pie cards (OS X)

Bought to use with an iMac Pro to house an Avid HD Native card, it has worked flawlessly from day one even though it's not on Avid's supported list. Not single complaint and very well built, even supplies data to two external monitors with a single hiccup.

très bon matériel

Reçu rapidement et fonctionne très bien. Ne chauffe pas et prise en charge de la carte vidéo sans problème. Raccordé sur un mini ordinateur sur sa prise thunderbolt 4, tout fonctionne parfaitement.

Mac mini 2014+OWC Mercury Helios 3Sの組合せでBoot Campで使用

【安定性】 Mac mini 2014(intel)で外付けGPUケース(OWC Mercury Helios 3S)と組み合わせて使用しています残念ながら、Mac(OS12.4)ではRadeon RX 6500と6400はサポートしていませんが、Boot Camp(Win10,21H2)では安定して動いています【画質】 DELLのFHDモニター(S2721H)を使用していますが、フルHD設定では特に問題ありません【静音性】ベンチマークで高負荷にしない限り、ほとんど無音です。むしろ、Mac mini 本体のシロッコファンの音の方がうるさいです【付属ソフト】 TriXXとAMD Softwareでカスタム設定ができるみたいですが、ほとんどデフォルトのままです【その他】試しに、FF15 Benchや3DMark Benchを回してみたところ、快適動作とはいきませんでしたが、それなりに楽しめます

Works great with my Mac but mixed results with windows

I bought this to host a blackmagic design Intensity pro 4k capture card. It worked fine with my Mac but not on my mini PC. For the PC I had to use an Echo Express PCI enclosure for the card to be recognised.

Expensive but works exactly as promised.

It does the trick. Very easy installation and works out of the box. Daisy chaining a second device is a very nice extra. The fan is a bit noisy, so I would recommend not placing it on your desk.
