MSI has gone so heavy with 12V-2x6 power sockets in its latest high-end PSUs that many AMD and Intel graphics cards have no way of being powered (www.pcgamer.com)

The reason why those two new PSUs only have one 8-pin connector is because they both sport two 12V-2x6 sockets instead. The company does offer PSUs with up to three 8-pin and one 16-pin power slots.

The only reason why anyone would want to use two 12V-2x6 cables is to have a PC with two Nvidia graphics cards but given that SLI is dead and long gone on the latest generation of GeForce GPUs, dual setups are purely for AI, to let you do your own training and inference.

I'm not sure about the AI angle. The product pages for the PSUs don't mention AI, and no company is going to make a product for AI and not mention AI.

It's more that there's not really any other use case for dual GPUs (without SLI/Crossfire) other than using those GPUs for stuff other than graphics processing. That means AI or crypto-mining in a VAST number of cases, with very very tiny subsets of users doing stuff like passthrough GPUs to a VM.

There exists no gpu that uses two of those connectors. The whole reason that connector exists is so that you can have a single connector going into any gpu. Thus, the only reason to have two, is to have two GPUs that use said connector. Right now, the main reason to sport two brand new top of the line Nvidia GPUs is AI. Is it the only reason? Not really, it can also be a professional setup for some kind of heavy workload.
