It has been a topic of discussion for a while now, some of the founder edition NVIDIA graphic cards ion the Ampere series 'could' get a 12-pin 12V power cable. Thus far it has been a rumor, whoever the first photos just popped up. 

And the photos this time come from none other than Seasonic, manufacturers of power supplies. The com,pany states that this is only for testing. The photo was published by an official Seasonic account on the Chinese social network Bilibili, Twitter user HXL noted. It would be the possible "graphical interface for the Nvidia GeForce RTX 30 series," the company writes. The cable has a single 12-pin connection for the video card and connects to a power supply via two standard 8-pin connectors. Such 8-pin connections can each supply a maximum of 150W of power, the 12-pin connector can supply up to 300W of power. Add 75 Watts from the PCIe slot and that's a max total design board power of 375 Watts. 

The cable has a length of 75cm according to the packaging. Nvidia will host a GeForce Livestream on Tuesday, September 1. The GPU manufacturer is expected to announce its upcoming RTX 30 video cards on that date.
