Nvidia’s swish GeForce RTX 4090 wowed reviewers and assign a brand fresh bar for staunch how stupidly like a flash a graphics card could well be. Sadly, the open of the $1,600 GPU has been marred by multiple experiences of melting 12VHPWR connectors old school in the cards detrimental every the connector and the GPUs at occasions.
The fresh 12VHPWR connector is a compact vitality connector that mixes the aptitude of multiple older 6- and 8-pin connectors into one diminutive crawl. It turned into as soon as originally adopted with the GeForce RTX 3090 Ti Founders Model and is now old school in the GeForce RTX 4090 Founders Model moreover to custom versions of the RTX 4090 built by the likes of Asus, MSI, et cetera. The 12VHPWR connector turned into as soon as furthermore old school in more fresh RTX 40-assortment graphics cards treasure the RTX 4080 and RTX 4070 Ti, although no longer in AMD’s Radeon RX 7000-assortment GPUs.
Updates: Reports of melting connectors had largely subsided but a spate of melted adapters the exhaust of third-birthday party CableMod has cropped with the company asserting it has bought 20 experiences with the majority of the topic likely being improperly inserted adapters. The GeForce proprietor who sued Nvidia claiming the cards are unsuitable has asked the court docket to forget his swimsuit with prejudice. While most melted connectors have occurred on the GPU, one Reddit poster is reporting a melted PSU this time.
With this like a flash-intriguing, confusing, and furthermore very serious articulate, PCWorld has decided to round up the facts you favor to grab to abet separate truth from fiction. Nvidia officials have declined to negate whereas it investigates, but the most up-to-date constructing seem to point out atrocious 12VHPWR adapter cables. There’s furthermore the likelihood that no longer fully inserting the cable could well cause increased resistance and adequate warmth to melt the connectors. We’ll update this legend as fresh data is launched.
Sept. 10 Hassan Mujtaba of WCCFTech experiences of an alert issued from PCI-SIG to participants of a “thermal variance, which can perhaps well lead to security considerations underneath particular security situations.” The member alert advises vendors to “work intently with their connector vendors and exercise due diligence in the exhaust of high-vitality connections”
Sept. 14 The total email and extra info from the PCI-SIG are reported by Stephen Burke of Gamers Nexus and notes that “screw ups were observed namely cable routing situations from PSUs and test boards that generate aspect load on the interface.” Burke acknowledged the document—it appears to be created by Nvidia—from PCI-SIG confirmed three diversified manufacturers were examined with 10 sample assemblies with screw ups manifesting from 10 hours to 30 hours with melting. It’s price pointing out that the interior document appears to debate with the connection on the PSU aspect—no longer the GPU aspect. In typical, however, ATX 3.0 vitality provides PCWorld have viewed trace the cables to be an identical on every ends.
Sept. 22 VideoCardz’s editor WhyCry experiences that GPU maker Zotac’s steering on the fresh 12VHPWR connector is rated for 30-insertion cycles which raises alarms as to the lifespan and sturdiness of the fresh connector. VideoCardz later amends its document to order that whereas 30 cycles appears to be very low, many Molex connectors introduced over the last 20 years have had identical mating cycles.
Oct. 24 The principle document of a melted 12HPWR connector is posted on the Nvidia sub-reddit. The GPU appears to be to be a Gigabyte 4090 Gaming OC the exhaust of an Nvidia-branded 12VHPWR adapter cable. Both Nvidia and Gigabyte attain out to the proprietor who experiences a exchange card has been bought. A 2nd document of a melted dongle is bought as properly on that day with wound to the adapter cable and an Asus RTX 4090 TUF Gaming OC Model going on. The Reddit put up as we deny goes viral on the high-profile graphics card with many assuming the fresh connector to be at fault.
Oct. 24 About a hours after the preliminary melting document on Reddit, eminent vitality provide reviewer and the thought in the inspire of PSU certification company Cybenetics, Aristeidis Bitziopoulos, makes an strive to replicate the melting 12VHPWR connector by subjecting it to 600 watt loads for additional than 90 minutes. He is unable to wound the cable whereas seeing only a exiguous thermal variance. It needs to be well-liked that the test old school a native 12VHPWR cable on an ATX 3.0 vitality provide in space of Nvidia’s adapter. Bitziopoulos concludes the 12VHPWR connector doesn’t appear to be a priority in his attempting out.

Oct. 26 The legit Reddit megathread itemizing exhibiting documented screw ups now numbers 5 damaged 12VHWPR connectors.
Oct. 26 Jason Langiven, aka JayzTwoCents, who has long been crucial of the connector being “harmful,” makes an strive to replicate the failure on a native 12VHWPR cable and is unable to induce a failure on the cable underneath heavy loads.
Oct. 27 Igor Wallossek of IgorsLab.de conducts a accelerate down and failure test of a 12VHPWR vitality adapter and concludes that the problem doesn’t appear to be the 12VHPWR form itself nor the much-touted insertion cycle concern raised beforehand. As a exchange, Wallossek concludes it is the form of Nvidia’s adapter itself, which he describes as “sinful quality (and) can lead to screw ups and has already triggered wound in single conditions.” Wallossek acknowledged he believes bending and kinking of the adapter could cause weak solder joints and bridges to interrupt and delay the resistance inflicting the melting.
Oct. 28 Ronaldo Buassali of TecLab.win.br posts his have confidence failure checks, collectively with swinging a vitality provide the exhaust of staunch the connector and subjecting to a stress test of 1,532—properly beyond its rated sustained wattage of 600 watts.
Oct. 30 Stephen Burke of Gamers Nexus makes an strive to replicate the melting failure by intentionally detrimental a 12VHPWR adapter an similar to what IgorsLab.de had reported and subjected it to a ninety nine p.c load for 8 hours with out a melting observed. Burke furthermore notes that his 5 adapters all appear to be constructed the an identical—and yet otherwise than the adapter IgorsLab had. Burke acknowledged his 5 12VHWPR adapters exhaust wires labeled for 300 volts versus the 150 volts the adapter Wallossek had. Burke concludes that we staunch don’t know what the problem is, but it no doubt is an precise field on some adapters—but no longer all of them. He furthermore mentions a theory being floated that the smaller connector could well no longer with out complications seat moreover to the upper typical vitality connectors. He furthermore positive aspects out that opposite to what many customers deem, a native connector that plugs as we deny into a vitality provide could furthermore fail the an identical map if the native cable is constructed the an identical because the failed adapters. Burke furthermore asks owners of RTX 4090 cards to document which cable adapters they’ve.
Oct. 30 With news that there appear to be diversified 12VHPWR adapters being equipped, Stephen Burke of Gamer’s Nexus experiences by Twitter that of the 130 emails he has bought, 7 p.c of homeowners document they’ve the 150V cabling that turned into as soon as old school in IgorsLab’s adapter cable. Burke notes that whereas the cable marking could well order 150V, that only map it uses the an identical apparent spec cables—and does no longer trace they’re can also have the low-quality solder joints that IgorsLab realized. Burke furthermore notes that of the 130, “no longer many are burned.”
Nov. 1 Ronaldo Buassali of TecLab.win.br posts a longer video of attempting out from the fashioned stay stream with extra explanations of how he examined the 12VHPWR. Unlike a quantity of the attempting out to this point, which old school exact GeForce RTX 4090 cards, Buassali physically removes the 12VHPWR connector from the GPU and wires it up for stress attempting out. This lets Buassali push the connector assembly properly previous the 600 watts known as for, collectively with a good deal of 900 watts, 1,200 watts and 1,500 watts. Buassali’s conclusion? The 12VHPWR connector itself is “properly sized, so much in yelp that it supported much extra than its specification.” On the opposite hand, Buassali concludes that although the connector can take care of extra than it’s rated for, a poorly inserted connector that creates resistance could certainly be in the inspire of the melting of the connector. Buassali furthermore doesn’t rule out a batch of atrocious cables, but that means a producing articulate, no longer a form field.
Nov. 2 Jon Gerow, director of R&D at Corsair and formerly of Jonnyguru.com, posts outcomes from intentionally damaged 12VHPWR cable adapters underneath load and is unable to induce melting as properly. Gerow turned into as soon as in a scheme to source multiple 12VHPWR adapter cables for detrimental attempting out, and in spite of breaking off solder joints, he turned into as soon as unable to induce melting or a failure. He did trace that just among the adapters weren’t constructed totally but even the worst of the batch handed stress attempting out with out failing. Gerow concludes that just among the complications can also have occurred when the owners didn’t fully seat the 12VHPWR adapter cables and furthermore posts photos of place in PCs the assign even a exiguous hole of 1 mm could well lead to increased resistance.
Nov. 3 AMD formally publicizes its RDNA3-basically based Radeon 7900XT and Radeon 7900XTX and proudly notes that it did no longer exhaust 12VHPWR connections. On the opposite hand, the company positive aspects out that the frequent perception that it modified its designs only after the melting complications cropped up just a few weeks in the past is no longer staunch. AMD made the selection to cease with typical 8-pin vitality connectors extra than a year in the past.
Nov. 4 A fresh put up in the Nvidia subreddit, taken from a Fb put up of a Hong Kong-basically based RTX 4090 proprietor, is the first reported damaged 12VHPWR cable from a native cable plugged as we deny into a vitality provide. Previous to this document, the total reported considerations had only occurred in 12VHPWR adapter cables, no longer native cables. The following day, any other individual experiences a melted connector the exhaust of a native 12VHPWR cable from an ATX 3.0 vitality provide. This appears to be to hump hopes that a native crawl would resolve the topic.
Nov 7 The different of confirmed failed connectors now numbers 23 on the Reddit megathread, with considerations spread among many graphics card makers. Oddly, there are no longer any Nvidia Founders Model cards listed with screw ups. There are furthermore 5 unconfirmed conditions listed from other board makers as properly.
Nov. 7 VideoCardz editor WhyCry experiences that a individual on Reddit has been informed his or her Gainward GeForce RTX 4090 will be delayed except the heart of November because it waits for exchange 12VHPWR adapter cables. The email, despatched from Australian PC company Techfast to a buyer, acknowledged “While investigations are peaceable persevering with and Nvidia has no longer launched a public assertion, Gainward has informed us that cables shipped with their cards will (are) being replaced. Due to this, they’re conserving transport of all cards except this has taken space. We furthermore realize this cable exchange is doubtlessly no longer restricted to Gainward by myself.” PCWorld reached out to Techfast who confirmed the authenticity of the email.
Nov. 8 Despite Australian PC builder Techfast confirming an email despatched to clients asserting some RTX 4090 cards can be delayed whereas Gainward ships exchange cables and implying other GPU makers would attain the an identical, Gainward’s EU Fb page says that’s no longer the case and has issued a clarification. “There’s wrong data suggesting Gainward is delaying the RTX 4090 cargo to change the cables recently. Here we would desire to provide an explanation for that—Gainward is no longer conserving any RTX 40 cargo to change the cables, and has no conception to attain so. The cables Gainward at the moment old school on the RTX 40 were inspected by NVIDIA personnel and realized no considerations. All Gainward cargo is being made as typical. Please don’t hesitate to take care of shut the Gainward graphics cards could well should you intend to aquire one!”

Nov 14 Igor Wallossek of Igorslab.de confirms there are at the least two manufacturers of the Nvidia equipped adapter plugs with one in every of the adapters apparently the exhaust of a rougher casting making insertions extra keen. Wallossek, who acknowledged he has spoken with Nvidia’s director of engineering Gabriele Gorla, doesn’t blame cease users, but does deem the rougher castings could well maybe have lead some clients to to rock the 12VHWPR connector into the socket which can perhaps well be why so many experiences demonstrate melted connectors ranging from one aspect of the connector with few to none melting from the heart. The solution, Wallossek acknowledged, could well trace the PCI SIG needs to articulate steering on take care of out zones to give customers better access to the socket to as we deny inserting it in space of rocking the connectors in from one aspect. Wallossek furthermore notes that of the two adapter cables old school equipped by Nvidia, one form only grabs pins on two sides whereas the opposite form grabs pins on all four sides.
Nov. 16 In an exhaustive investigation counting on third-birthday party failure evaluation the exhaust of X-ray examination moreover to electron microscope examination, moreover to reproducing the screw ups, Gamers Nexus’ EIC Stephen Burke concludes debris in some unspecified time in the future of the connectors from manufacturing or from insertion moreover to improperly seating the cables is largely in the inspire of a quantity of the screw ups viewed. Burke furthermore cites numbers from a seller that the threat of failure is from 0.05 to .1 p.c at this point. Even supposing improperly seating the cables whereas putting it underneath stress appears to win a quantity of the blame, Burke furthermore wonders if the form of the connector shouldn’t have anticipated the considerations.
