Why did Intel/nVidia went for the new connector for 12v, 600w, and not reuse something off the shelf

Why did Intel/nVidia went for the new connector for 12v, 600w, and not reuse something off the shelf

Like, There is xt60, which is rated for 60A, so about 720w Some modified version that could be used Or, there is xt90,

And if you feel like it, use 2 xt 60 connections

Or, just 2 banana plugs would have been better, instead of this mess

Even 2 blades, like on car fuses, could easily handle that much power easily,

The new 12 pin pcie connector has 12 pins, with the adapter having 24 merge to 12, They are actually pushing more current through less surface area, and causing heat?

Can GN or LTT do a voltage drop test across the connector?

It will shed light on this whole fiasco
