A few weeks ago a curious thing started happening to gamers whose PCs are powered by the ASUS Z690 Hero motherboard – their systems started to catch fire.
Reports of smoldering boards started surfacing on Reddit and various forums.
ASUS issued a recall on the product, or rather what they call a “replacement program.”
With the internet ablaze with reports of faulty ASUS motherboards, a few netizens got to work on finding the root cause, and it turned out to be a simple manufacturing and assembling mistake rather than a design flaw. Netectives noted that a single capacitor was installed in a reverse position causing reversed polarity, and enough heat for the components to fail and catch fire.
