Nvidia says it’s investigating two reports of RTX 4090 playing cards which have had power cables burn or soften. Reddit consumer reggie_gakil was the first to post particulars about their Gigabyte RTX 4090 points yesterday, displaying burn harm on the brand new 12VHPWR adapter cable that Nvidia ships with the RTX 4090. The connection on the precise card was additionally broken and melted.
A second Reddit poster replied to the identical thread displaying off related harm to an Asus RTX 4090 graphics card power connector.
“We are investigating the reports,” says Nvidia spokesperson Bryan Del Rizzo in a press release to The Verge. “We are in contact with the first owner and will be reaching out to the other for additional information.”
Nvidia initially moved to this new 16-pin power connector for its personal RTX 3090 Ti playing cards, and it has now turn into an ordinary on the RTX 40-series GPUs throughout distributors. There are considerations that the 12VHPWR power connector, which is designed for brand spanking new ATX 3.0 power provides, may trigger points if it’s bent a sure means.
The 12VHPWR connector and terminals are quite a bit smaller than the earlier technology, and cablemod warns that “it appears that bending the wires too close to the connector could result in some of the terminals coming loose or misaligning within the connector itself.” The website recommends not bending a connector vertically or horizontally, and as an alternative having a minimal distance of 35mm from the connector earlier than any bends happen.
That’s relatively troublesome in observe, with Nvidia’s adapter hitting the aspect panel in most fashionable instances. The unique Reddit poster vertically mounted their RTX 4090, which implies the cable may have bent earlier than the minimal distance.
YouTuber JayzTwoCents, who has been warning about this new connector for weeks, calls it “dangerous,” however says Nvidia doesn’t agree. “I think you’re worrying about issues that don’t exist,” mentioned Brandon Bell, a senior technical advertising supervisor at Nvidia, in an e mail to Jay final month.
In early September, PCI-SIG — an trade consortium liable for creating requirements round peripheral part I/O knowledge transfers — warned that some implementations of the 12VHPWR connector “have demonstrated thermal variance, which could result in safety issues under certain conditions.”
Images provided by PCI-SIG present a number of methods a connector may soften or burn, and are the end result of excessive bends throughout testing. The melting seems similar to what has occurred with each of the Reddit posters’ RTX 4090 playing cards this week.
The options to those points could be to keep away from Nvidia’s power adapter altogether, or be very cautious about the way you place or bend it. It’s a cumbersome adapter that’s provided with RTX 4090 playing cards, and wishes as much as 4 8-pin power connectors. Power provide distributors are beginning to ship 12VHPWR cables that ditch the cumbersome connector for a single cable that terminates into two 8-pin power connectors on a PSU. Corsair sells its own for $19.99.
These cables ought to assist keep away from the awkward bends we’re seeing with these new connectors, significantly in opposition to the edges of instances. New ATX 3.0 power provides will assist too, however there aren’t many in the marketplace and never many PC players will wish to spend additional to switch a working PSU simply to get a local implementation of the 12VHPWR connector.
