Implementations
link link link link link link link link link

1 For macOS 10.13.4: AMD RX480/580 & these are supported. Nvidia support can be added with an app workaround with good success.
2 Flex-ATX (fATX) PSUs have a tiny 40mm high RPM cooling fan that is noisy under load. Separate external-AC PSUs are not included in product’s size.
3 Meet or exceed your intended video card’s peak power requirements. See TechPowerUp card reviews, eg: GTX1080Ti to find this.
4 Meet or exceed your TB3 notebook’s charger wattage for the TB3 enclosure to be a single-cable solution that includes charging. eg Macbook USB-C chargers.
5 ports’ use reduces eGPU bandwidth by up to 31.2% @10Gbps, 15.6% @5Gbps. Except for (i) Displayport devices (ii) XG Station 2 that hosts ports off a separate USB-B cable.
5 If used on a TB2/1 system via a
US$49 Apple TB3-TB2 adapter, USB ports are not visible in Windows (inc Aorus’ fan control). They do appear in macOS. Ref: theitsage.
6 Allows eGPU detection in Windows for systems reporting “external GPUs supported: no” in the Intel Thunderbolt software.
7 If require a longer TB3 cable, consider these:  US$55 Choetech 200cmUS$60/$50 Cable Matters 200cm/100cm.

1 For macOS High Sierra: AMD RX480/580 & these are supported. Nvidia support can be added with an app workaround with variable success.
2 Flex-ATX (fATX) PSUs have a tiny 40mm high RPM cooling fan that is noisy under load. Separate external-AC PSUs are not included in product’s size.
3 Meet or exceed your intended video card’s peak power requirements. See TechPowerUp card reviews, eg: GTX1080Ti to find this.
4 Meet or exceed your TB3 notebook’s charger wattage for the TB3 enclosure to be a single-cable solution that includes charging. eg Macbook USB-C chargers.
5 On macOS: TI82 enclosures require TB3-enabler, a kext system file modification tool, to allow eGPU detection.
6 2nd TB3 port can be used for daisy chaining, as a 10Gbps USB-C 3.1 or Displayport. Note: Intel disallows a 2nd TB3 port on eGFX enclosures. It’s only for PCIe enclosures.
7 ports’ use reduces eGPU bandwidth by up to 31.2% @10Gbps, 15.6% @5Gbps. Except for (i) Displayport devices (ii) XG Station 2 that hosts ports via a separate USB-B cabled USB switch.
7 If used on a TB2/1 system via a US$49 Apple TB3-TB2 adapter, USB ports are not visible in Windows (inc Aorus’ fan control). They do appear in macOS. Ref: theitsage.
8 Allows eGPU detection in Windows for systems reporting “external GPUs supported: no” in the Intel Thunderbolt software.
