Be Quiet! 12VHPWR PCIe Adapter Cable BC072

Product Information

No matter which variant you choose, this 12VHPWR 180 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. NOTE: Please refer to product dimensions as well as the chosen variant to ensure compatibility with your graphics card before purchasing. Your power supply must have 2x free PCIe connectors available where the Seasonic 12VHPWR’s 2x PCIe connectors can plug into. BOTH 2x8 Pin PCIe connectorsof the 12VHPWR must be connected into the power supply. Nov. 1 Ronaldo Buassali of TecLab.net.br posts a longer video of testing from the original live stream with additional explanations of how he tested the 12VHPWR. Unlike most of the testing so far, which used actual GeForce RTX 4090 cards, Buassali physically removes the 12VHPWR connector from the GPU and wires it up for stress testing. This lets Buassali push the connector assembly well past the 600 watts called for, including loads of 900 watts, 1,200 watts and 1,500 watts. Buassali’s conclusion? The 12VHPWR connector itself is “well sized, so much so that it supported much more than its specification.” However, Buassali concludes that even though the connector can handle more than it’s rated for, a poorly inserted connector that creates resistance could indeed be behind the melting of the connector. Buassali also doesn’t rule out a batch of bad cables, but that implies a manufacturing issue, not a design problem.

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.

To ensure peak performance, our angled adapters use a 2oz copper PCB with applied copper foil to aid heat dissipation. Combined with a thermal pad and a quality aluminum shell, this multi-layered design helps keep things cool, even under continuous loads. Oct. 24 The first report of a melted 12HPWR connector is posted on the Nvidia sub-reddit. The GPU appears to be a Gigabyte 4090 Gaming OC using an Nvidia-branded 12VHPWR adapter cable. Both Nvidia and Gigabyte reach out to the owner who reports a replacement card has been received. A second report of a melted dongle is received as well on that day with damage to the adapter cable and an Asus RTX 4090 TUF Gaming OC Edition occurring. The Reddit post immediately goes viral on the high-profile graphics card with many assuming the new connector to be at fault.

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. Oct. 25 Former HardOCP editor Kyle Bennett reports AMD’s upcoming RDNA3 GPUs will not use the 12VHWPR connector in its reference designs. Neither Bennett, nor his sources at AMD indicate when the design decision was made to skip 12VHPWR. 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. 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.Nov. 4 A new post in the Nvidia subreddit, taken from a Facebook post of a Hong Kong-based RTX 4090 owner, is the first reported damaged 12VHPWR cable from a native cable plugged directly into a power supply. Previous to this report, all of the reported issues had only occurred in 12VHPWR adapter cables, not native cables. The following day, another person reports a melted connector using a native 12VHPWR cable from an ATX 3.0 power supply. This appears to dash hopes that a native plug would solve the problem. Feb. 2023 Intel releases a minor update to the ATX 3.0 spec that recommends that power supply vendors use internal connections using spring-type rather than dimple-type connections. Intel said it did this as the suggestion of connection companies themselves as the spring-type design offers more surface area. The different connection recommendation, however, does not mandate it for all, and older dimple-style connectors can continued to be used if a power supply vendor chooses to. Existing power supplies using dimple-style connectors also do not need to be replaced—they work as expected if inserted correctly. 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.

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. 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. 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. 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.He continued: "I know we’re not only the only ones being told to do this, as I’ve already seen renders of power supplies out there with two of the 12VHPWR connectors on the modular interface when using a one-to-one 12VHPWR cable. And there have been discussions about adding a second 12VHPWR connector to the ATX 3.0 test plan.”
