Question about Sonnet eGFX Breakaway Box 550

I have contacted the manufacturer. The models indicated on the website are to be understood as a reference for the 550 in terms of power consumption. The manufacturer's reply:

The compatiblity table is for power compatibility. If your 970 card has 8-pin + 6-pin power connectors, you can use Breakaway Box 350. If you card has 8-pin + 8-pin, you need Breakaway Box 550.

Breakaway Box 350: 8pin + 6pin Connector
Breakaway Box 550: 8pin + 8pin Connector

The manufacturer's page is somewhat irritating. Under GPU Card Family Support, the following NVidia models are listed in the Tech Specs:

NVIDIA GeForce GTX Titan Xp
NVIDIA GeForce GTX 1080 Ti
NVIDIA GeForce GTX 1080
NVIDIA GeForce GTX 1070
NVIDIA GeForce GTX 1060
NVIDIA GeForce GTX 1050 Ti
NVIDIA GeForce GTX 1050
NVIDIA GeForce GTX Titan X
NVIDIA GeForce GTX 980 Ti
NVIDIA GeForce GTX 980
NVIDIA GeForce GTX 970
NVIDIA GeForce GTX 960
NVIDIA GeForce GTX 950
NVIDIA GeForce GTX 750 Ti
NVIDIA GeForce GTX 750

However, no 9xx models from the various manufacturers are listed under Graphic Cards.

It is best to ask the manufacturer directly what is actually the case and whether your graphics card is supported. If you receive a corresponding answer, you can then answer the question directly yourself.
