This allows for a maximum power of 662W but the official specification will set the limit at 600W. Of course, that's still massively higher than the up to 150W provided by the current pin connector.
Just as we said, the power connector has 16 lanes in total (12 power and 4 signal lanes), but it’s not a MicroFit Molex standard, but something entirely new. The standard defined as has smaller spacing than existing connectors, a change from 4.2 mm to 3.0 mm. The connector has a width of 18.85 mm, so it is not exactly small, but much smaller than dual or triple 8-pin connector configuration. This will greatly simplify the circuit and PCB design process, not to mention all the space that will be saved.Allegedly, the upcoming NVIDIA GeForce RTX 3090 may be the first card to feature the high power connector.
