Nov. 18 After weeks of mostly silence, Nvidia finally issues a statement that it has received 50 known reports of melted connectors and after analyzing the returned cables, has largely found improper insertion to be the likely cause, according to a report by Gamers Nexus. The company also poured cold water on building concern that use of third-party 12VHPWR cables would void warranties. The company told Gamers Nexus EIC Stephen Burke that it would honor warranties related to the issues and would expedite the RMA process. While improper insertion would indicate user error during installation of the the cards is to blame, Nvidia also told Gamers Nexus it is looking at ways to improve the connectors that was homologated by the PCI-SIG. You may want to tread carefully if you have an off-brand power supply, but Corsair told us that all of their power supplies would have this scenario covered without issue. They also told us that the difference between ATX 2.0 and ATX 3.0 power supplies really isn’t as significant as some are making it out to be. Many of the improvements in ATX 3.0 were incorporated into earlier revisions of ATX 2.0, with the most notable new change being the 12VHPWR connector. Long story short, you really don’t need to be worried about having an ATX 3.0 power supply or about pulling too much power through your "old-school" PCI Express power connectors if you buy a new graphics card that uses 12VHPWR. Our 12VHPWR 90 Degree Angled Adapter only protrudes 21mm from your graphics card, which means increased space and more clearance between your GPU and your side panel. This enables installation of super wide cards in more narrow chassis. Oct. 25 Showing what a distraction the 12VHPWR has become, AMD’s Scott Herkelman publicly confirms the new Radeon cards will skip 12VHPWR and receives responses such as “That is a HUGE relief, happy with that news.”

As previously touched on, there are a number of CableMod 12VHPWR Angled Adapter models available. Firstly, you can choose between a 90-degree or 180-degree model. These are then also split into two variants, Variant A and Variant B. Their primary difference is how the 16-pin connector is orientated. Variant A has the 16-pin header above the side-band pins, whilst Variant B is the other way around. Sept. 10 Hassan Mujtaba of WCCFTech reports of an alert issued from PCI-SIG to members of a “thermal variance, which could result in safety issues under certain safety conditions.” The member alert advises vendors to “work closely with their connector vendors and exercise due diligence in using high-power connections”

Nov. 13 There are now 26 confirmed GeForce RTX 4090 GPUs with melted connectors documented in the Nvidia subreddit including for the first time, a report of an Nvidia GeForce RTX 4090 Founders Edition with a melted connector. Sept. 22 VideoCardz’s editor WhyCry reports that GPU maker Zotac’s guidance on the new 12VHPWR connector is rated for 30-insertion cycles which raises alarms as to the lifespan and durability of the new connector. VideoCardz later amends its report to say that while 30 cycles appears very low, many Molex connectors introduced over the last 20 years have had similar mating cycles. No matter which variant you choose, this 12VHPWR 90 Degree Angled Adapter looks great with its sleek styling and unobtrusive design. Available in multiple colors, there’s sure to be an adapter that matches the theme of your build.

Before the RTX 4090 launched, a few concerns were bruited about regarding the safety limitations of this connection, as well as about powering GPUs with it using an adapter. But these aren’t really things worth worrying about. The first of these red flags was raised by PCI-SIG, which warned of a potential issue when using the 12VHPWR connector. But the issue encountered occurred during something resembling torture tests that they were performing on the 12VHPWR. Achieve cable management nirvana with the CableMod 12VHPWR 90 Degree Angled Adapter. This low profile adapter plugs into your graphic card’s 16-pin 12VHPWR port, and enables the power cable to be plugged in at a 90 degree angle. Featuring a reinforced PCB design and a sleek profile, this adapter helps increase clearance between the GPU and the side panel – perfect for today’s super wide GPUs. This is the newest v1.1 revision, which includes improved terminals and the new CEM 5.1 female connector. The CableMod 12VHPWR 180 Degree Angled Adapter comes in two variants, making sure there’s a solution for graphics cards no matter which 12VHPWR power port orientation they have. For those who prefer a more traditional cable layout, a 90 Degree Angled Adapter, which routes the cable below the graphics card, is also available. With this fast-moving, confusing, and also very serious situation, PCWorld has decided to round up the facts youneed to know to help separate fact from fiction. Nvidia officials have declined to comment while it investigates, but the latest development seem to point to bad 12VHPWR adapter cables. There’s also the possibility that not fully inserting the cable may cause increased resistance and enough heat to melt the connectors. We’ll update this story as new information is released. The CableMod 12VHPWR 90 Degree Angled Adapter comes in two variants, making sure there’s a solution for graphics cards no matter which 12VHPWR power port orientation they have. For those with extra tight space requirements, a 180 Degree Angled Adapter, which routes the cable above the graphics card, is also available.

Two Configurations

Nov. 18 The official Nvidia Reddit megathread closes out its logging of reported incidents which appear to drop off after Gamers Nexus video and Nvidia’s official notice. However, one Reddit user posts an image of a melted RTX 4090 12VHPWR connector in the PCMR subreddit on Nov. 24. There are two variants of the CableMod 12VHPWR 16-Pin 90-Degree Adapter. The graphics card you have will dictate which variant you choose. This is Variant A, which is less than 23mm deep with the 16-pin connector above the side-band pins. Nov. 2 Jon Gerow, director of R&D at Corsair and formerly of Jonnyguru.com, posts results from intentionally damaged 12VHPWR cable adapters under load and is unable to induce melting as well. Gerow was able to source multiple 12VHPWR adapter cables for destructive testing, and despite breaking off solder joints, he was unable to induce melting or a failure. He did note that some of the adapters weren’t constructed very well but even the worst of the batch passedstress testing without failing. Gerow concludes that some of the problems may have occurred when the owners didn’t fully seat the 12VHPWR adapter cables and also posts images of installed PCs where even a small gap of 1 mm could result in increased resistance.

The NVIDIA GeForce RTX 40 Series has brought next generation gaming to our beloved PCs, but it has also brought a new connector. As well as some teething issues to boot. With the CableMod 12VHPWR Angled Adapters, things just got a whole lot easier. What Does The CableMod 12VHPWR Angled Adapter Do?

For as long as I can remember, I've had love of all things tech, spurred on, in part, by a love of gaming. I began working on computers owned by immediate family members and relatives when I was around 10 years old. I've always sought to learn as much as possible about anything PC, leading to a well-rounded grasp on all things tech today. In my role at PCMag, I greatly enjoy the opportunity to share what I know. Oct. 24 A few hours after the initial melting report on Reddit, renowned power supply reviewer and the principle behind PSU certification company Cybenetics, Aristeidis Bitziopoulos, attempts to replicate the melting 12VHPWR connector by subjecting it to 600 watt loads for more than 90 minutes. He is unable to damage the cable while seeing only a small thermal variance. It should be noted that the test used a native 12VHPWR cable on an ATX 3.0 power supply rather than Nvidia’s adapter. Bitziopoulos concludes the 12VHPWR connector doesn’t seem to be an issue in his testing.
