Corsair GPU Power Bridge, designed to handle 100+ degrees, melts GeForce RTX 4090

Ever since the GeForce RTX 40 Series first debuted on the scene back in 2022, led by the 450W flagship GeForce RTX 4090, there's been a steady stream of reports related to cables overheating, melting, and even damaging the GPUs they're connected to. The latest case actually dates back to this era, to the original 12VHPWR connector, which the safer 12V-2x6 connector has since replaced. Of course, there are still issues with the newer connector, but this is a gentle reminder that even a GPU that has been using the older 12VHPWR connector for more than a year is still at risk.

According to a new post on Reddit from 'Dry-Relationship5158,' they were using a GeForce RTX 4090 Founders Edition paired with the original Corsair Power Bridge adapter for 12VHPWR GPU connections. The 180-degree design of the adapter was developed for users seeking a cleaner look and to avoid bending their GPU power cables near the pins. Corsair's product page for the Power Bridge adapter says it's rated for up to 55A and can withstand temperatures up to 105 degrees Celsius, making it the right choice for a "power-hungry GPU" like the GeForce RTX 4090.

For this one Redditor, however, after their PC began freezing and randomly restarting every time they tried to fire up a game, unplugging the Power Bridge revealed a "total nightmare."

According to the post, the connection on the GPU side "completely melted" along the top row of pins, and the damage and overheating also caused the GeForce RTX 4090's power connector to deform and melt, rendering the GPU unusable.

The reason why the user posted this on Reddit was that the Corsair Power Bridge and the GPU itself are no longer covered under warranty, so they were wondering what they need to say in their Corsair support ticket and to find out if this would be covered, as issues related to 12VHPWR connectors are both prevalent and something that potentially should be covered outside of warranty. The good news for Redditor 'Dry-Relationship5158' is that Corsair's social media team spotted the post pretty much right away and are already escalating it internally.
