This is what the new power connector for GeForce RTX 50 cards looks like. What will change?
GeForce RTX 50 Blackwell graphics cards will probably receive a new power connector. We already know what it will look like and what changes it will introduce compared to the previous one.
Yesterday (February 19) we reported that GeForce RTX 50 series graphics cards are to have a new 16-pin power connector. We didn’t know its details back then, but that’s what has changed. We know how the new connector will differ from the previous one.
New 12V-2×6 H++ power connector
Let’s start with the fact that GeForce RTX 40 graphics cards received a 12VHPWR power connector. This turned out to be not well thought out and, if connected incorrectly, could damage the GPU.
Therefore, over time it was changed to 12V-2×6, which looks the same in theory, but in practice is much safer. This was due to, among other things, shorter pins, thanks to which – if the plug is not pressed – the mechanism does not allow the transmission of energy at full power, so the risk of failure is much lower.
H++ 12V-2X6 (max: 675w)
H+ 12VHPWR (max: 600w)

Now NVIDIA is planning another change. The 12V-2×6 connector will be replaced by 12V-2×6 H++. The marking itself suggests that the changes will not be major. The most important one concerns the maximum energy that can be transmitted. For the older variant, it is a maximum of 600 W. In the case of the new one, we are talking about 675 W. Apart from that, looking at the photos, the differences are minimal.
NVIDIA is to use the new connector in GeForce RTX 50 cards. It is still unknown whether AMD will take the same step. The company is apparently open to it, but only when they are sure that the newer standard is fully safe for cards and users.
