As graphics cards get more power hungry, the need to develop a new power connector arises. Igor's Lab has shared the schematics for a high-power PCIe power connector tailored for PCIe 5.0. The power connector could debut with the next generation of AMD and Nvidia graphics cards.
The 12VHPWR power connector consists of 16 pins in total, four more than Nvidia's 12-pin PCIe power connector. It would appear that the chip maker was on to something or somehow anticipated the direction in which PCIe power connectors were going. With the 12VHPWR power connector, there are 12 power contacts with four smaller signal contacts at the bottom of the connector. For the moment, it's unknown what's the purpose for the signal contacts.
