Nvidia’s confident that their RTX 50 series won’t have melting power cable issues

Nvidia believes that the age of melting power connectors is over

In a recent statement to QuazarZone, Nvidia seems confident that its RTX 50 series GPUs will not suffer from melting power cables or connectors, despite the fact that their RTX 50 series has GPUs with TDPs as high as 575W.

After the launch of Nvidia’s RTX 40 series GPUs, it was found that some users had their GPU’s 12VHPWR connectors melt, destroying their GPUs. This could happen when 12VHPWR cables are not fully inserted. As a result, the 12VHPWR connector was revised to create the 12V-2×6 connector. This new power connector features recessed sense pins and longer power pins. This ensures that full/correct cable insertion is required for full power delivery.

After this new connector was developed, new RTX 40 series GPUs were produced using it, retiring the 12VHPWR connector. Over time, this stopped RTX 4090 GPUs from suffering from this melted cable/connector issue. As such, Nvidia expects melting cables and connectors to be a thing of the past with the launch of their RTX 50 series graphics cards.

We do not expect that to happen with the RTX 50 series. We made some changes to the power connector to respond to the issue at the time, and we know that it is not happening now, about two years later.

Nvidia’s RTX 5090 GPU has a TGP of 575W. That’s 125W higher than Nvidia’s RTX 4090. This fact has left many concerned about the safety of 12V-2×6 power connectors. Regardless, Nvidia appears confident in the capabilities of 12V-2×6 power connectors. We recommend taking your time when using these power connectors and ensuring that they are fully inserted before powering on your system.

You can join the discussion on Nvidia’s belief that its 12+4-pin power connector issues are resolved on the OC3D Forums.
