A server is not a personal computer. We are talking about enthusiast GPUs here who will install these components into their existing setup whereas servers are usually sold as a unit including the power supply.

Bold of you to assume that Nvidia would be willing to cut into its margin to provide an optional feature with no marketable benefit other than electrical safety.

Why would that be optional on a top of the line GPU that requires it? NVIDIA has nothing to do with it. I'm talking about defining an extended ATX standard, that covers PSUs, and it would be optional in the product lines of PSU manufacturers. The 12VHPWR connector support in PSUs is already a premium thing, they just didn't go far enough.
