NVIDIA’s RTX 5090 Founders Edition graphics cards had a wide repercussion in the world of technology with the melting problems that emerged on power ports. This has brought the power cable burning cases again two years ago in the RTX 4090 models. As the source of the problem, the connection deficiencies in the 12VHPWR cables, which are the power connection standard, are pointed out. The fact that users did not correctly install this power cable or caused the melting of the cables that do not fully sit down under energy, was one of the previously discussed issues in the sector. However, despite the use of a more advanced cable standard in the RTX 5090, similar problems continue to be experienced.
A user report shared in Reddit revealed the details of the distress. A user after switching to RTX 5090 graphics card Battlefield 5 While playing, he reported that he smelled from his computer. After the incident, he said in his investigation, both the graphics card and the power supply of the melted plastic marks, he said. This user said that he used a special 12VHPWR cable from a manufacturer named Modiy and that the cable was set correctly from both ends. However, a similar problem took place with a different power cable brand.
Spanish technology content producer Toro Tocho has faced the same type of melting on its RTX 5090 Founders Edition graphics card. Tocho, although the power supply manufacturer uses an original cable provided by FSP, he detected melting both on the graphics card and in the power supply. This shows that the problem cannot only be attributed to a particular cable manufacturer or user error. Considering that the card consumes 575 Watt energy, concerns about the correct design of the connection points came up. NVIDIA is thought to take more measures in power management and connection reliability.
NVIDIA has switched to a new version developed by PCI-Sig after the problems in the 12VHPWR connection standard introduced with RTX 40 Series graphics cards. This new standard is called 12V-2 × 6 and contains shorter detection pins and longer conductive terminals. According to experts, these changes were designed to ensure that the connection is safely sitting. In addition, some power supply manufacturers began to use colored pins on the cable. The appearance of these pins can show the user that the connection does not fully fit.
Although the NVIDIA applied the 12V-2 × 6 connection on the new generation RTX 50 series cards as standard, it is still possible to use the old 12VHPWR cables. But here, safety risks continue. AMD refuses to adopt this connection standard and continues to use the 8-PCI PCIe connections, which are more traditional on graphics cards. In fact, AMD officials, 12VHPWR connection had a risk of fire had already expressed the risk of a fire.
