GeForce RTX 4090 Overheating phenomenon, 2 cases in Korea

NVIDIA GeForce RTX 4090 graphics card overheating was confirmed not only in the United States but also in Korea. As of the first two cases, the number of cases in the United States and two domestically increased on the 28th.

Overheating of the power supply terminal is caused by using a conversion cable that converts the PCI Express power terminal of the existing ATX 2.2 standard power supply to the ATX 3.0 standard ’12VHPWR’ terminal.

NVIDIA informed major graphics card manufacturers on the 27th that they sent products that had overheated problems to the US headquarters.

■ It occurs regardless of load or manufacturer

According to Reddit (USA) and major domestic PC-related communities, the 12VHPWR power terminal or conversion cable of the GeForce RTX 4090 graphics card is melted or transformed. It is identified as a case.

Most consumers who had problems were easily recognized for overheating because the screen was suddenly turned off or burned while running the game. However, in some cases, the PC is notified even if there is no problem, or after the news, the news and the cable are notified.

The problem is happening regardless of the load of graphics cards such as high-end games and low-end games. It is also not a matter that appears only in certain manufacturers.

An official of a domestic corporation said, If you have received an inquiry from consumers who have experienced overheating problems, and if the product is in stock as a customer support center, it will be processed according to the free warranty regulations after checking the product.

The most likely cause of overheating phenomena is the conversion cable that NVIDIA supplies the GeForce RTX 4090 graphics card.

The power supply for desktop PCs, which has been distributed so far, has not been equipped with cables that can be inserted directly into the 12VHPWR terminal. For this reason, NVIDIA is supplying cables that convert the PCI Express power cable of the existing power supply to a 12VHPWR terminal.

German IT Media Good Lab said on the 27th (local time), The conversion cable provided by NVIDIA soldered four 14AWG (2.5 mm diameter) power wire on the 12VHPWR terminal. It can be ruined. The pin at the interior connection is too thin.

If you connect a 12VHPWR cable directly to the graphics card with a power supply that follows the ATX 3.0 standard, there is no problem yet.


■ RTX 4090 equipped graphics card, sales of more than 1,500 in Korea

NVIDIA is currently investigating the cause of overheating problems. It will take a considerable time to get the exact cause and solution.

According to foreign sources such as The Barges and WCCF Tech, NVIDIA informed major graphics card manufacturers on the 27th to send products that had overheated problems to the US headquarters.

According to distribution officials, the GeForce RTX 4090 graphics cards sold in Korea are estimated to be more than 1,500.

Major domestic subsidiaries who responded to the coverage said, We have not yet received specific support measures or recommendations for consumers through NVIDIA’s headquarters.
