Found possible 12VHPWR connector melting issue on Nvidia RTX 4090 graphics cards
For several days, photos of Nvidia RTX 4090 video cards with melted 12VHPWR power ports have been walking around the network. Several such cases are known, and even on finished PCs, which were assembled by specialists, not enthusiasts. While Nvidia itself is investigating, a possible explanation has emerged.
Igor Wallossek of Igor’s Lab reported that the problem was with poor quality adapters. He opened one of them and it turned out that four wires, through which +12 V is supplied, are soldered to a thin copper base – its thickness is a fraction of a millimeter, and its width is 2 mm. This makes the soldering unreliable and increases the resistance, and hence the heat. In addition, if the middle lines are soldered to two contacts, then the extreme lines are soldered to only one.
Testing has shown that it is very easy to tear off the wires. This can be done even with the usual installation of a video card. Critically vulnerable are just the extreme wires, which users complained about.
At the same time, the 12VHPWR connector itself is designed normally, the problem is just in the adapter. This confirms the fact that modern power supplies with a 12VHPWR connection do not cause reflow.
The company has not yet made an official statement in this regard. However, apparently, the supplier of adapters, not Nvidia, is to blame.

World’s first 31″ domed OLED display and 65″ curved 8K monitor unveiled

TCL CSOT announced a number of new displays, including an interesting new domed OLED gaming monitor for PC.
The new gaming monitors were unveiled at DTC 2023 (Global Display Tech-ecosystem Conference 2023), which is taking place in Wuhan, China. The new gaming monitor is equipped with a 31-inch dome-shaped OLED panel with a resolution of 4K and a frequency of 120 Hz, and the dome shape, according to the developers, allows you to give a 3D feeling. There are very few details about the model yet.
Jun Zhao, CEO of TCL CSOT, said: “With significant advances in display technologies including LCD and OLED, we have made remarkable breakthroughs to provide superior user experience. We will continue to provide high-quality products for a variety of scenarios, working closely with our industry partners.”
The company also introduced a 27-inch 8K monitor with eye tracking and 3D support.
The world’s first curved OLED IJP monitor with a 65-inch diagonal, 8K resolution and a frequency of 120 Hz was announced. Its resolution is 7680 x 4320 pixels.
It also unveiled the world’s first 14-inch hybrid laptop with a 2.8K OLED IJP screen that supports an adaptive refresh rate of 30-120Hz.

Small, but remote. Corsair unveils SSD MP600 Micro in M.2 2242 form factor

Most modern solid-state drives have the M.2 2280 form factor, but sometimes you need a much more compact SSD – M.2 2242. Corsair did just that.
In the photo you can see the MP600 Micro model in the specified form factor. The length of such a drive is 42 mm, although there is also an M.2 2230 that is only 30 mm long.
The new product supports PCIe 4.0 and is characterized by data transfer speeds of up to 5100 MB/s for reading and 4300 MB/s for writing. Performance is respectively 600,000 and 890,000 IOPS. These parameters are typical for the 1 TB model, which also has a resource of 600 TBW.
It remains to add that the new product is based on 176-layer Micron 3D TLC NAND memory and is priced at $70.

Huawei defeated American sanctions: the Chinese company now has its own 5-nanometer processor

Five years under strict American sanctions, which cut Huawei off from advanced single-chip systems, have yielded results: the company has its own 5-nanometer processor made in China.
There is an interesting story with this processor. Five days ago, Huawei introduced the Qingyun L540 laptop based on the Kirin 9006C SoC: and at that time, all the characteristics of the device were revealed, but nothing was reported about the central element of the hardware platform. Now Huawei has updated the description on the website, which clearly states that the Kirin 9006C is manufactured using the 5 nm process technology.
The official description says that the single-chip system has eight cores and a maximum frequency of 3.13 GHz. The Gizmochina resource adds: the CPU is made according to a two-cluster design – with four Arm Cortex-A77 cores and four more Arm Cortex-A55 cores.
Let’s remember that earlier Huawei had a 7-nanometer SoC Kirin 9000S, and it is used in the flagships of the Mate 60 line. Kirin 9000S is produced by SMIC, and the same company most likely produces the 5-nanometer Kirin 9006C.
