RTX 5090 power connectors dissolve from NVIDIA

Oh shit, here we go again. Two of the new NVIDIA owners RTX 5090 Editions GPU reported on the melted power connectors and the damage to PSUS. Pictures look identical to reports Burning RTX 4090 power cables Or melting two years ago. Nafidia blame The problem is for people who do not connect the 12VHPWR energy connection completely and the body of PCI standards Blame on Nafidia.

Reddit Poster It was promoted from RTX 4090 to RTX 5090 and noticed “a burning smell playing Battle Square 5“Before turning off their computer and finding the damage. The burning plastic images appear at the end of the PSU for the power connector and the part that connects directly to the graphics processing unit. The cable is one of materialThe famous manufacturer of the customized cables claims, and the poster claims to be “securely installed and clicked on both sides (GPU and PSU).”

While it is tempting to blame the Spanish Moddiy cable Youtuber Toro Toccho The same burning cable (in both GPU and PSU ends) witnessed the RTX 5090 Founders version while using a cable provided by the PSU manufacturer FSP. Plastic has also melted in the PCIe 5.0 Power connector on the power source.

NVIDIA originally provided 12VHPWR power connector on RTX 40-Series graphics units, and power supplies also appeared for the first time to support the new standard. The RTX 4090 Founders has managed to pull 450 watts on the 12VHPWR connector, while the new RTX 5090 pulls up to 575 watts on a cable of up to 600 watts. After early problems with the melting of the RTX 4090 connectors, PCI-Sig, the standards organization responsible for the 12VHPWR conductor, has now updated to a new 12V-2×6 connector on the side of GPU and in some cases the PSU side as well.

The 12V-2×6 connector has shorter sensor pins and a longer leader’s stations, to improve reliability. “This may not seem a big difference, but it is important to ensure properly connecting the power cable to any device that will withdraw power from the power source in your system,” Corsair explains.

NVIDIA 12V-2×6 connects use RTX 50-Series graphics units, but you can still use existing 12vHPWR cables. “In order to be clear, this is not a new cable, it is an updated change on the nails in the socket, which is referred to by 12V-x6,” says Corsair. PSU manufacturers such as Corsair and MSI are built on their 12VHPWR cables so that you can still see yellow or gray pins, this means that the conductor is not present properly.

While Intel and AMD are both a member of the PCI-Sig collection that helped develop the 12VHPWR power conductor, only NVIDIA has adopted the standard so far. Until next AMD Radeon RX 9070-Series They use 8 pin PCIE connections instead. AMD suggested that the 12VHPWR connector was a fire danger in late 2022, when the company’s game marketing manager SASA Marinkovic was Tweet “Stay safe in the holiday season” along with a picture of 8 tooth connectors.

12vHPWR was She described “garbage fire,“Thanks to the design processes that make it relatively easy for the final users not to properly connect the cable safely. Cablemod was too too Forced the summons Power transformers 12vHPWR GPU last year after reports of the melted transformers.

We have contacted NVIDIA to comment on the latest reports on the RTX 5090 power connector problems, but the company did not respond in time to post.
