New connector food 12VHPWR present in graphics cards Nvidia This continues to cause many problems. Above all, the graphics cards most affected are the RTX4090, the graphics that consume the most from NVIDIA. Well, two years later, NorthridgeFix claims to be repairing around 200 RTX 4090 graphics cards per month because the power connector is burned out.
High-end graphics cards from AMD and NVIDIA have very high consumption. These charts already required three PCIe connectors of 8 pins and it was especially a problem when managing cables. NVIDIA, Intel and the PCI-SIG regulator therefore collaborated to develop a unified high-power connector, called 12VHPWR.
Graphics card damage continues
First of all, you should know that the NVIDIA RTX 4090 was launched on September 20, 2022 and was one of the first to use the 12VHPWR connector. A connector designed to save space and improve cable management. This connector can deliver up to 600 watts of power and also includes four management pins that communicate with the power supply to improve power management.
According to NorthridgeFix, approximately every month repair nails 200 NVIDIA RTX 4090 graphics cards. Most (if not all) models are from 2022 and use the 12VHPWR power connector.
Initially, this power connector had an apparent design flaw that caused poor contact. When the load was high and, therefore, its consumption was greater, the faster the connector suffered damage. A burning effect was generated there which melted the plastic of the connector, rendering the graphics card useless.
Due to the proliferation of problems, NVIDIA had to act quickly to stem the bleeding. The company announced the new 12V-2×6 connectoran updated version of the connector.
But, the connector change comes well after the launch of this graphics card. Any models prior to the change are therefore likely to be damaged at this stage. In fact, the burning of the connector is a matter of time and depends on its use. The greater the usage and the more demanding the game, the quicker it will take damage.
How can I stop my NVIDIA RTX 4090 from burning out?
The problem doesn’t seem to be just with the connector, it also affects cable management. Several power supply manufacturers have been forced to add power wiring installation instructions for the 12VHPWR connector, also known as the PCIe 5.0 connector.
According to the textbooks, two points stand out. The first is that you have to make sure that the connector is inserted well, that there is no space between the cable connector and the graphics card connector. This space due to a design flaw would be the cause of the problems.
It should be noted that this poor power docking issue does not occur in the 8-pin PCIe connectors. This does not happen since it has a safety and anchor tab that prevents incorrect installation. The 12VHPWR connector does not have this element and this is where part of the problem arises.
In addition, power supply manufacturers provide details on the cable. They point out that there cannot be any type of bend within 35mm of the power connector. From what they state, the reason would be the 450-600 watts it can provide.
