NVIDIA has responded to the RTX 4090 12-pin power cable concerns pertaining to melting / burned 12VHPWR cables. The company has provided a statement on the situation, given a failure quantity, and has commented that it will be replacing all affected units under warranty. GN was able to source new information from board partners pertaining to NVIDIA sales count and, using this new 50-unit number provided by NVIDIA, we can now get an accurate range for failure rate. We also talk about how to properly install an NVIDIA RTX 4090 or RTX 4080 and how to properly connect its power cable. The tutorial at the end shows correct 12VHPWR (12-pin, "16-pin") cable installation for these GPUs.
