[Hardware] The power connector for NVIDIA graphics is now secure

We have seen in the past how a few NVIDIA graphics cards have caught fire due to the power cable. The new 12VHPWR connector, which is a solution for high consumption, seems to have been not very well developed. NVIDIA, without saying anything, would have updated the specifications of the 12VHPWR connector which makes it noticeably more secure.

The problem with modern graphics cards is high consumption. There are many models that require three 8-pin PCIe power connectors. This connector is many years old and appears insufficient for current needs.

Not only does this proposal exist, which is already used, a connector has also recently appeared directly on the motherboard. The alternative is not completely convincing, because it would increase the wear of the motherboard itself. Several current options that, in no case, convince.

Fixed the new power connector for the graphics
As we have mentioned, the new 12VHPWR power connector developed by NVIDIA has not turned out well. There have been a few RTX 4090 and RTX 4080 that have been burned due to deficiencies in the connector. Apparently, the problem is that it would not finish making contact correctly.

 

 

HardwareBusters and power cable manufacturer Linwell have recently published a security analysis. According to their latest tests, these new power connectors are completely safe. Now, even if it is not perfectly connected, we will not have problems.

PCI-SIG, which regulates this standard and others, released new specifications in July. A rushed update after dozens of RTX 4090 and RTX 4080 suffered power connector issues.

NVIDIA, in a display of genius, said that the problem was with the users, who did not connect the cables correctly. Many indicated that the connectors were not well manufactured.

The HardwareBusters test uses cables from Linwell, the manufacturer of power cables for ASUS. They have tested the cable for 15 minutes delivering about 55 amps. The temperature of the connector has been verified and is around 45-46 ºC throughout the test.

To have all the information, they have bent the cable at a 90º angle and connected them incorrectly, imitating the conditions that, theoretically, damaged the NVIDIA RTX 4090. Under these conditions, the temperature ranges between 40-41 ºC, insufficient for burn or melt.

According to HardwareBusters, the new pins are more conductive than the previous ones. These new pins have less resistance to the passage of electricity, even when there is high consumption.
