NVIDIA's RTX 40 Super GPUs Feature New 12V-2x6 'H++' Power Connector

The latest 12V-2x6 power connector offers enhanced durability and supports up to 675W, marking a significant improvement over its predecessor.

Not all NVIDIA RTX 40-series Super GPUs use the new 12V-2x6 connector; some models still feature the older 12VHPWR connector.
The 12V-2x6 'H++' connector can handle up to 675W of power, compared to the 600W supported by the 12VHPWR 'H+' connector.
The introduction of the 12V-2x6 connector follows issues with the 12VHPWR connector, which was prone to melting in high-stress conditions.
Despite the improvements, a few RTX 4070 Super variants are still equipped with standard 8-pin PCIe power connectors.
NVIDIA is expected to continue using the 12V-2x6 'H++' connector for future GPU models, aiming for higher power delivery and reliability.
