The 12VHPWR connector arrives to replace the traditional 4-pin and 6-pin PCIe connector. We have seen in recent years graphics cards with up to a total of three 6-pin PCIe connectors to power them, which is a problem.
As a solution, NVIDIA has developed a connector that has been certified by the PCI-SIG. This is a regulatory consortium that is responsible for the standardization of different elements. Said regulator has stressed in the past that it must be the manufacturers who guarantee safety.
Twist with the NVIDIA graphics connector mess
The new solution for powering graphics cards It allows “transmit” until 600 watts by a single cable. The problem lies with the RTX 4090, which would be causing the connector burn out. Note that this graphics card would have a maximum consumption of 450 watts, far from the theoretical maximum of the cable.
Something that has traditionally been done in gaming computers is to use different power cables. There are cables of many colors on the market, anyone can even customize the cables with colored “sleeves”.
Cable Mod csells different types of cables feeding with different colors. This brand has been adopted by many users around the world. Within its catalog it offers, as it cannot be otherwise, cables with 12VHPWR connector.
A Reddit user who goes by the name of “Harpartap” has explained his problem. He has said that he has used one of the cables of CableMod of type 12VHPWR for feed his RTX 4090. The graphics card has been damaged for the cable and, as it is under warranty, has tried to process the RMA.
The maker of the RTX 4090what is MSI does not intend to cover the issue. The brand says that he adapter of CableMod has defects of quality and design. Also, they tell them to talk to this company and that they are not responsible.
What happened at the end?
CableMod has promised to give you your cable money back without any hassle. The brand claims that the failure rate of this adapter is low, although higher than conventional or standard 12VHPWR cables. They have confirmed to this user that they are going to release version 1.1 of this adapter shortly.
About the graphics card? MSI flatly refuses to process the warranty, saying that they are not responsible. They simply tell the user to get by with CableMod.
Given the uproar on Reddit, CableMod has contacted the user to give him more help. Specifically, this brand will cover the graphics card if MSI still refuses to process the RMA to repair or replace the burnt RTX 4090.
In the meantime, a new power connector has been developed that is installed directly on the motherboard. Come on, the problem is transferred elsewhere, being able to generate two damage products in the future due to “connector problems”.
