NVIDIA 16-Pin “12VHPWR” Connector Issues May Be Due to User Error, JonnyGuru Points Out

JonnyGuru explains that users may not fully insert the 16-pin “12VHPWR” connector cable into the graphics card, which would cause problems with the connector itself, with wires melting and connectors overheating. This theory is not new, as previously discussed, but it is one of the ideas that have been brought up in tech circles by content creators, experts, and media sources. This also remains a theory, as no complete evidence supports the idea. However, JonnyGuru shows us how he reached this verdict with hardware and connection issues of the NVIDIA GeForce RTX 4090 GPU. First, the Corsair PSU specialist uses a Corsair HX1500i, using three PCIe cables connected to NVIDIA’s 16-pin “12VHPWR” adapter. Included in the test is a thermistor to monitor temperatures and binding around the wires to ensure the wires don’t bend as much. To start the problem, it started to destroy the connectors, especially the durability of the joints that were welded to the connection. Everything was still in place after this test and the temperature remained as high as 53°C. He then researched all known cases of melted and distorted connections, examining each published image and comparing the intact connections to those that were part of the melting and overheating issues. Recognizing similarities in all manufacturers, he came to a single conclusion. ANY 12VHPWR connector can potentially burn because ANY of them can be difficult to insert. … VERY HARD to enter completely. — JonnyGuru, Corsair power supply expert NVIDIA hasn’t revealed any details or answers to the public since it launched. It is known that the company has addressed this issue with the highest priority. Meanwhile, a new notice is shared by PCI-SIG, which may imply a new revision of the 16-pin “12VHPWR” cable to be published by December 6, 2022. The last control zone indicates that an ECR change request has been submitted or Engineering and will close on December 20, 2022. ECR = engineering change request interesting, what will change right now🧐🧐🧐 pic.twitter.com/iFOioScvkl — chi11eddog (@g01d3nm4ng0) November 8, 2022 Are you willing to buy a graphics card with the 12VHPWR 16-pin connector cable?
