Nvidia Investigating Reports of Melting RTX 4090 Video Card Cables

The company says so far a common issue is that connectors are not being fully plugged in.

Nvidia's GeForce RTX 4090 is a monster card with a huge price that generates a lot of heat. So much heat that it could damage the cable connections. The issue appears to stem from connectors not fully plugged into the card, Nvidia said Friday in an update on its support page

There are about 50 cases of this happening, according to the company. "We are actively investigating the reports," Nvidia said in the update. It advises card owners to ensure the cable is firmly secured before plugging the card into the motherboard. 

A few owners of the GeForce RTX 4090 cards began sharing pictures of burned cable connections on the Nvidia subreddit just weeks after the card came out. The 12VHPWR adapter is the cable that goes from the computer's power supply to the card, and because of the power required to run RTX 4090, a lot of heat builds up, especially if the cable bends at a right angle in order to fit the giant card into a PC case. 

Nvidia said it's working with its partners to replace the cards affected. 

The GeForce RTX 4090 came out last month at a whopping price of $1,600. It's one of the best video cards available for PC gaming rigs, especially for those gamers who want to play games in 4K.
