The first pictures of the upcoming High-Power Connector for PCIe 5.0 compatible graphics cards have been pictured by Igor's Lab. Designed for next-generation graphics cards, schematics of the power connector show that it will allow up to 600W of power to be delivered directly to the GPUs.

According to Igor Wallossek, the existing power delivery systems are becoming obsolete as GPUs become more power-hungry. This generation saw the most graphics cards from NVIDIA and AMD to feature triple 8-pin connector interfaces. While NVIDIA opted for a 12-pin Microfit solution for its own Founders Edition variants, AIBs were reluctant to use the new power standard but the stopgap made them ready for the true deal and that's the upcoming PCI Express 12VHPWR connector.
