Nvidia RTX 5090 Power Connectors Meltdown: Deja Vu?

Nvidia's RTX 5090 Founders Edition is facing another power connector meltdown crisis, eerily similar to the RTX 4090 issues from two years ago. Two users reported melted power connectors and PSU damage, with images showing burnt plastic on both the PSU and GPU ends of the cables, even using cables from reputable manufacturers like MODDIY and FSP. While Nvidia previously blamed improper cable insertion, this recurrence highlights concerns about the 12VHPWR connector design. PCI-SIG has updated the connector to 12V-2x6 for improved reliability, but RTX 5090s still support older 12VHPWR cables. AMD, which uses traditional 8-pin PCIe connectors, previously hinted at 12VHPWR being a fire hazard. The 12VHPWR connector continues to face criticism for its design oversights.
