https://www.techpowerup.com/251440/powercolor-shows-off-new-thunderbolt-3-egpu-enclosures-at-ces-2019 Starting with the TBX-750FA this external GPU enclosure uses a Thunderbolt 3 (40Gbps) connection and has a 750-watt internal power supply. Due to the size of not only the enclosure but the power supply as well, graphics cards measuring up to 335 x 170 x 58 mm (13.18 x 6.69 x 2.28 inches). When you factor in maximum GPU power is rated at 500-watts pretty much any GPU on the market should work with this enclosure.
The TBX-240FU or Mini Pro version will come with a Radeon RX 570 8 GB and has an extra fan for improved cooling. It also offers up 1x Gigabit ethernet, 2x USB 3.0, and of course a Thunderbolt 3 port for connecting to the host system.
The Mini Pro with RX 570 is expected to cost $499, while the regular Mini is listed for $359. Later on, a standalone enclosure with no GPU will be released for $199. I think the standalone is good if you already have a GPU to go inside of it.
