EVGA has shown off a dual-way GeForce RTX 3090 Ti KINGPIN graphics card configuration which is running a quad-way 16-Pin Gen 5 connector config.

When EVGA unveiled its GeForce RTX 3090 Ti KINGPIN Hybrid graphics card, it was only one of the two graphics cards that rocked dual 16-Pin Gen 5 connectors. A dual 16-pin Gen 5 connector config runs through a triple 8-pin power adapter for each connector so that means for a dual 16-pin input, you will need six 8-pin power plugs leading from the power supply to the adapter.
