The Nvidia RTX 4090’s power draw may be too much for its power connector to handle

Nvidia’s GeForce RTX 4090 $1,599 It is an incredibly powerful graphics card, but its performance comes at the cost of a high power draw. Like a few RTX 3000 series cards, Nvidia uses a new type of 16-pin 12-volt-hour power connector to supply all that power to the card — you can plug in up to four 8-pin GPU power cables into the 12VHPWR adapter, which then plugs into the connector on the GPU, freeing up some board space.

But at least two RT 4090 users are now reporting that their 12VHPWR connectors have overheated and melted during use. these complaints be its source from reddit (Via Tom’s Hardware), so take it with caution – we don’t know the exact configuration of any of the users’ PC setup. The specific model of the graphics card (A Gigabyte RTX 4090 Gaming OC for a single user, Asus RTX 4090 TUF Gaming OC Edition For the other), the power supply and any number of other factors could have contributed to the conductors overheating.

For its part, Nvidia told Tom that it is “investigating the reports” and that the company is “in contact with the first owner” and plans to communicate with the other. We’ve followed up with Nvidia and will update this article if the company has more information to share.

Tom’s Hardware speculates that the problem may be caused by a bend in the cable too close to the power connector, causing some of its pins to “misalign” or loosen, which can result in an uneven load of power across the pins. We will monitor the issue until it becomes clear if these are one-time failures or a sign of a more systemic issue with the RTX 4090 series.
