The reason behind failing of EVGA GeForce RTX 3090 graphics cards was a poor PCB design

We have seen the latest news circling around the internet where we heard the news of GeForce RTX 3090 graphics cards getting damaged. However, according to the latest information, EVGA has found the reason behind this and it’s actually related to the PCB design.

The problem started in July when 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.

When the game was booted and it was played for a few minutes then no soon than that the card would end up permanently damaged. This problem was major news and led to RMAs and an initial investigation showed that the problem could be a bad PWM fan controller which led to abnormal functions.

The developers of the RPG game, New Worlds, 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.

Early theories that EVGA’s cooling system was to blame are also incorrect, the spokesman said.

In no way shape or form, is it related to the fan controller,” he said.

All of the cards were earlier production run cards manufactured in 2020. Under an X-ray analysis, they appear to have “poor workmanship” on soldering around the card’s MOSFET circuits that powered the impacted cards.

The company declined to say how many GeForce RTX 3090 cards it has sold but did characterize this small-batch as significantly less than 1 per cent of the total.

Accoridng to reports, the issue occurred with the initial batch of EVGA GeForce RTX 3090 graphics cards which were produced in 2020. however, the cards manufactured prior to 2021 featured bad soldering around the card’s MOSFET circuits and this little mishap was the major culprit.

But the problem was such major that it took the EVGA around 2 months to figure the solution out it just shows the state of Quality Control over at EVGA where the company failed to discover this major design flaw firsthand back in 2020 and let them ship to the retail segment.
