There’s another 12VHPWR connector meltdown, this time the bitter master is replaced by a TUF Gaming GeForce RTX 4090

After GIGABYTE, ASUS TUF Gaming graphics card also appeared.

Following the GIGABYTE GeForce RTX 4090 Gaming OC graphics card, after the 12VHPWR connector and adapter cable melted down in the US discussion forum reddit, under the same discussion forum, other players also said that their TUF Gaming version GeForce RTX 4090 OC from The the same problem occurs with the graphics card.

The player mentioned in the discussion forum that he was playing the game Black Desert at the time of the incident, and suddenly the computer had a black frequency and the fans were spinning at full speed.

Judging from the pictures, this 12VHPWR adapter cable is indeed the wire designated by NVIDIA, because the NVIDIA Logo is printed on it; if there is no accident, the supplier of this adapter cable is Astron, which is also a designated manufacturer of NVIDIA.

We did not test the TUF Gaming GeForce RTX 4090. In the earlier test of the ROG Strix GeForce RTX 4090 graphics card, we used a thermal imaging analyzer to illuminate the 12VHPWR connector, and we can see the temperature of two locations of this melting Under the default condition 500W, it is 52.8 and 54.1 degrees respectively.

During testing, we did not use the 12VHPWR adapter cable that came with the graphics card, but the 2x 8 PIN to 12VHPWR cable provided by the ASUS ROG Thor series power supply. During our entire testing and burn-in process, whether NVIDIA adapter or
Thor’s power supply wires have not melted.

At this stage, the GeForce RTX 4090 series graphics cards launched by various AIC partners all come with a 12VHPWR adapter cable, most of them are 4x PCIe 8 PIN to 12VHPWR, only a few graphics cards are come with 3x 8 PIN TO 12VHPWR adapter cable.

The 12VHPWR connector is a new specification developed by the PCI-SIG organization for PCIe 5.0 graphics cards. It was introduced in the Intel ATX 3.0 specification, but it can also be seen on some ATX 2.x power supplies The current PCI-SIG board members include AMD, Intel, Qualcomm and NVIDIA.

There have been two cases of 12VHPWR connector and adapter cable being destroyed in a row, and more “cases” may happen one after another, but so far NVIDIA has not responded to this.
