I remember mentioning something about how thin cables lead to smaller connectors, and the connection is gonna be the failure point in such a setup. So obviously, the smaller the connector, the bigger that chance of failure.

I wish it was easier to search through my posts. If someone stumbles upon the thread in which I talked to people about this, give me a link, ok?

In any case, if you get a 40 series Nvidia GPU, watch this video, and be careful how you plug that 12V power cable.
