# What is the difference between 12V-2X6 and 12VHPWR?

The latest 12V-2x6 "H++" power connector recently made debut on the NVIDIA GeForce RTX 40 SUPER series GPUs and offers slightly higher power delivery versus the existing 12VHPWR "H+" connectors.

12V-2×6 "H++" Connector Offers Up To 675W GPU Power Delivery Versus 600W 12VHPWR "H+" Plug.

* H++ Power Connector = 12V-2x6 Design (675W Power Delivery)
* H+ Power Connector = 12VHPWR Design (600W Power Delivery)

The new 12V-2x6 power connector is fully compatible with the 12VHPWR connector. In essence, the new 3.1 connector appears almost identical, is fully interchangeable, and can perform all the functions of the old connector, but with enhancements in safety and efficiency. Specifically, the power pins have been extended by 0.25mm to enhance connection reliability by enlarging the contact surface area and reducing temperatures. Additionally, the signal pins have been shortened by 1.5mm to ensure users have an easier time fully plugging in the connector to achieve the safest, most reliable connection.

The 12V-2×6 H++ connector is available in dual-color for visual confirmation and in a sleek all-black version.
