Nvidia's RTX 5090 power cables may be doomed to burn

RTX 5090 FE with melted power connector.

As the RTX 50-series rollout continues, users are experiencing what seems to be a shockingly high rate of failure. The proprietary 12VHPWR/12V-2x6 cables providing power to the graphics cards have been seen melting inside the GPU slot of 5090 and 5080 cards. Nvidia was confident that users would no longer see the same issue that also plagued the RTX 4090 thanks to the redesigned 12V-2x6 connector, but multiple skeptics are raising their voices in dissent, asserting that Nvidia is making its cards less safe with each generation.

YouTube channel BuildZoid and an Intel engineer's viral Reddit post both claim that the 12VHPWR standard is being pushed too far for safety, from two different angles. BuildZoid contends that Nvidia has consistently removed safety regulations like shunt resistors from its cards generation-over-generation, contributing to a high risk of burning and other dangers.
