NVIDIA Used 12V-2×6 Connector Design Instead of 12VHPWR On GeForce RTX 4070 GPUs

wccftech.com:

NVIDIA has apparently used the new 12V-2x6 power connectors on its GeForce RTX 4070 FE GPUs instead of the 12VHPWR design.

A few days ago, it was reported that PCI-SIG had a new CEM 5.1 specification designed around the existing 12VHPWR connector. This new connector standard was termed as the 12V-2x6 design and was said to feature various little changes and conformality with the ATX 3.1 standard to avoid all of the issues encountered on the initial 12VHPWR designs

Taking a closer look at the GeForce RTX 4070 FE from NVIDIA, Igor's Lab has now discovered that the card may already be using the newer 12V-2x6 pin power connector and the difference is visible from the four sense pins at the bottom of the primary 12-pin port. The difference is that while the older CEM 5.0 specification had a 0.45mm offset for the four sense pins, the new CEM 5.1 spec has modified that to a 1.7mm inward offset.

The same is the case with the MSI GeForce RTX 4070 Gaming X Trio custom variant which features a shortened 1.7mm offset but the connector itself has the 12VHPWR H+ label. There are supposed to be two connectors, the H+ and H++ so the proper design still hasn't been made available but it is stated that ASTRON would be mass-producing it but it is very interesting that a non-finalized design is already making its way to consumer GPUs.

It may be possible that this new revision can reduce a lot of melting issues associated with the older connectors. The new 12V-2x6 power connector will be featuring design spec for 150-300W cards too so future RTX 4050 & RTX 4060 series cards can also make use of that instead of the 8-pin plugs that are currently in use.
