No more overheating and melting?

CableMod introduced its original 12VHPWR angled adapter promising that it would solve overheating and melting issues surrounding Nvidia's adapter, but its aftermarket adapters appeared to also be prone to failures. Recently the company rolled out version 1.1 of its 12VHPWR angled adapters that adopt the new PCI SIG CEM 5.1 specification.

CableMod's 12VHPWR V1.1 (12V-2x6) angled adapter offers CEM5.1 compliance and is said to offer an improved friction-fit of the male connector which removes the wiggle between PCB and male connector. The device costs $39.90/€39.90 and is designed to solve issues with overheating and melting 12VHPWR dongles and adapters, both from makers of graphics cards and CableMod itself.

The updated PCI SIG 5.1 (12V-2×6) plug presents several modifications when compared to the original 12VHPWR connector. Firstly, the depth of the power terminal has been expanded from 4.2 mm to 4.45 mm. In addition, the sideband pin array's opening has been widened, moving from the previous measurements of 1.6 mm × 9.3 mm to 1.70 mm × 9.4 mm. One of the most notable changes, however, is the reduction of the sense pin length from 4 mm to 2.5 mm, ensuring that the power header is fully integrated with the connector. 

This adjustment is especially vital for safety reasons. If power connector is not adequately connected, the power supply avoids entering high power modes. This prevention mechanism stops potential overheating and possible melting situations, especially when a graphics card is drawing considerable energy. 

In response to the issues with the 12VHPWR connector, the PCI SIG set clear specifications for the new PCI SIG 5.1 (12V-2×6) design. They mandated a minimum current rating of 9.2A per pin, ensuring a temperature rise limit doesn't exceed 30 degrees Celsius above the ambient temperature at 12V DC. These connectors will bear an embossed H mark. Moreover, even if a single pin can manage a current of 9.2A, the entire assembly's current should not cross 55A RMS in either direction. The design also specifies the use of 16 AWG wires and pins and mandates that the connector can resist a pulling force of a minimum of 45.00N. 

One of the interesting things about the new 12VHPWR V1.1 (12V-2x6) adapter is that CableMod gives owners of the original adapter a $39.90/€39.90 coupon to buy themselves the new version of the device. Essentially, owners of the version 1.0 can get themselves a 12VHPWR V1.1 (12V-2x6) adapter for free.

    From the article.... One of the interesting things about the new 12VHPWR V1.1 (12V-2x6) adapter is that CableMod gives owners of the original adapter a $39.90/€39.90 coupon to buy themselves the new version of the device. Essentially, owners of the version 1.0 can get themselves a 12VHPWR V1.1 (12V-2x6) adapter for free.

    For free? Is this a Joke? The custom angled CM adapters should have been recalled. But Cablemod prefered not to do and instead offer a free replacement program. And you need pay shipping a second time. Pay more for a product that shoould have been recalled? That's much cheaper for them than issue an official recall. But I expect they was afraid for even worse damaging of their already sinking reputation. And the tech channels/webpages eat it freely.. That's sad.

    I still believe that NVIDIA should be paying for all these cable replacements. They knew. There is no way they could not have known.

    I have the original and love it. Nothing wrong with it. I will take the new version for free thank you. Now I will have 2 and will use both. Why all the anger did yours melt or just want to be all angsty about something someone else is having an issue with...

    Same, I've been using the 180 deg V1 Cablemode 12VHPWR connector without any issues and plan on getting another 180 deg angled connector for free. This is very nice of cablemod, knowing some folks with the V1 had issues.

    I am confused on which one to get - the 90 or 180 degree. I think I will order both and see which one fits my build with the ASUS TUF (or maybe the Strix) 4090. I am mounting the GPU upright in the new Lian Li O11D EVO XL case. If you go on the Lian Li website, the main image of the new case is the ASUS Strix GPU, but I'm having trouble picturing in my head which way the power cable will run. I think I need the 180 degree adapter, but not sure.

    Thanks CableMod! My original adapters worked fine. The Free Newer ones look very nice. I just ordered several adapters and cables from CableMod.

    These are nice quality products. The Adapters and Cables are top tier! I custom ordered 90° cables to connect directly into some of my EVGA power supplies. (ie no adapters just the cable). You can customize the Color of each individual wires on the cable, how many combs, Length etc.

    I literally saved hundreds because of the Coupons. (We got one for each of the Adapters and Cables we originally bought).

    While it's nice that the PCI-SIG and CableMod revamped the 12VHPwr to be more robust, it's important to remember that the internals of a computer, while generally more serviceable by the average person, was not meant to be serviced by the average person. Or at least the expectation is that it wouldn't be serviced by the average person. So having some things be a little more finicky is par for the course, because the expectation is whoever's touching it knows what they're doing and makes sure that everything is in its proper place.

    I mean, if you have a car, take a look under the hood. For the most part, you can service it as long as you have the right tools and whatnot. But the engine bay of a car was not designed for muggles to mess with because the expectation is you'd take it to a mechanic.
