EVGA has finally confirmed the main cause behind its GeForce RTX 3090 graphics cards getting damaged and it's related to the PCB design.

Back in July, several users playing Amazon's latest MMO, New Worlds, started reporting that their brand new EVGA GeForce RTX 3090 graphics cards were dying while playing the game. All it took was to boot the game, play it for a few minutes and the card would end up permanently damaged. This led to major RMAs and initial investigation showing that the problem could be a bad PWM fan controller which led to abnormal functions. New Worlds developers had to issue a quick frame cap to mitigate the problem but it looks like the problem was a poor design flaw from the start.
