Article is a summary of der8auer’s video. Measurements show 22A/260 watts – nearly half of the card’s power draw – going through a single wire heating it up to 150 °C in an open-air test bench.

    I don’t understand how the ATX standard hasn’t adopted higher voltage rails for GPUs. Higher volts mean fewer amps which means less heat. 44A through an 8 pin connector is going to make a lot of heat. 11A at 48v would be much better.

      Apple did something similar, then they put 48V pin next to 3V pin 🤦

      It’s mostly just one loud person who very apparently has not actually interacted with the case presented here. Either through ignorance or to purposely deflect the blame from Nvidia with the evidence weighing against them.

      Case is ground, and one big +12V pipe through the middle. Or, alternatively, the other way around for theft protection.

      A 48V rail would make more sense. Just like USB-C did to get 240W power delivery over a small cable.

      There wasn’t even anything wrong with the minifit jr 8 pin pcie connectors, the official spec of 150W massively derated. If Nvidia really wanted to cap the number of plugs and not change any specs then the 8 pin EPS connectors are rated at 288W.

        If they did that then they likely would end up with melted 8 pin connectors as that derating is a protection against one pin being overused due to small expected differences in resistance on each pin

        Using custom cables even in that scenario would still lead to cables melting.

        It’s from increasing the cable length and therefore the required power draw to draw the required amount to power the device. It already happens with 8pin systems as well, this isn’t unique to the delivery system either.

        Using too many extension cords has the exact same affect… it’s like blaming the heater because the cords melted. But no, let’s not blame physics, let’s blame the GPU(heater) -.-

          Now you’re really showing how uniformed you are. It’s not an extension cable, it’s 20cm in length total which is significantly shorter than what comes with standard 12Vhpwr native PSUs at 60-70cm.

          Math cares? With a smaller sample size, even a handful of issues makes the percentage of problems fairly high.

      Two. Two guys. One of which had cables melting away at casual gaming, the other of which had 150°C reached (and it would go higher over more time) in an open environment.

      And even if it’s only those two, that’s two too many.

        Why? Products fail all the time. Consumers who spend entire paychecks and stand in lines for hours to buy the newest Product Don’t have the right to complain that the product hasn’t been vetted yet. Spend your money on something important, not some trendy new gadget for your gaming PC. You can wait one year on the product will be tested and vetted, or it will have been removed from shelves because it was faulty to begin with, and the price will have come down. Your assertion that “two is too many” suggests that these consumers should be protected from their own poor spending decisions and is wrong to do so.

          Because Roman showed very clearly in the video the issue isn’t the device or the user, it’s inherit in the design. Pushing that much current through those small cables is a really bad idea. It’s needed to make everything smaller, but it has way too many failure cases. Even a small imbalance can cascade into dumping all that energy in one little cable, causing the plastic to melt and burn.

          I’m used to consumer protection (laws) … the kind that, you know, protects you from spontaneous fires, infinitely accelerating and exploding cars or toxic ingredients, especially if those products are supposed to be officially premium products, not bypassing those laws by importing directly from china under false names and Cina Export instead of CE. And in this case, that obviously failed, to a worrying degree.

          Consumers should be protected from literal fire hazards.

        Wasn’t the one using a custom cable? Most of these are user error.

        Edit, Jesus guys, this is basic electricity principles…

        Adding length to electrical cables increases the power draw, adding connections increases resistance, which increases power draw.

        So yeah, let’s add cables and connections that add draw and be shocked when it fucks up. Dude who made the video is just an idiot that doesn’t understand the base issue. It’s not the cards or adapter, it’s the fricken cable even though the guy doesn’t understand how voltage works apparently….

          The custom cable was smaller than the stock cable for a ITX case.

          That’s the point: It’s explicitly not. Both where very aware of the issues and checked the connection multiple times. Also, if you’re talking about custom cables, which cables would not be custom? The only official cable is the adapter from nvidia, all others are 3rd-Party. Roman (der8auer) even uses an on-brand cable, explicitly says and shows the connection and says he tried to push it in further multiple times during the test.

          So no, it’s most of the time not user error.

            If you’re not pushing the connecter in right or running it in a way that you pinch a cable, that’s user error. You’re creating hot spots by not connecting it correctly. That can only be described as a user error.

            And yes the first was an off the shelf third party custom cable… Linky

              - That’s what they made sure to check multiple times. That’s the points. It’s exactly what not happened, everything was connected correctly
              - Every cable is a thid party custom cable. The only exception may be a cable from NVidia themselves, which is only an adapter from 3*8Pin to 12VHPWR - there is literally no first or second party 12VHPWR cable. So what should they use instead - nothing? Wire it up themselves? That would be the only non-third party cable they could have. And in both cases, the cables where very high quality. So no Aliexpress crap.

                I see the issue. The guy wants to claim him using non-approved cables doesn’t make it a “user issue” what a dumb take.

                He didn’t even do a test without a cable and only using the adapter. So he doesn’t even have a base comparison… this is why random people shouldn’t be taken as gospel on shit like this. People latch onto the wrong stuff and run with it.

                Use a non-approved cable shocked pikachu face when it inevitably melts….

                Don’t you think there is a reason why Nvidia specifies NOT to use custom and non-approved parts…?

                Yeah using the wrong parts and being mad that it doesn’t work, is a user error. Also the article blames the cards, the CABLES are at fault. Dudes a shitty journalist and can’t see he caused his own issues. Yeesh.

                Than as the other user said, bad device…… it’s not the andapter unless it’s faulty or you damaged it. Using non approved custom cables falls into the user error area. If this was actually a design issue, this would be affecting far more cards and official adapters.

                No they aren’t. Mines plugged in with the one that comes from Nvidia. You can buy other brands, which is what causes most of these issues. Nvidia says not to use them for reasons…

                No Nvidia is a proprietary adapter, using someone else’s would make it custom.

            Use a non-Approved custom cable and be shocked when it melts…? Yeah a user using non approved parts makes it a user issue, it’s nothing to do with Nvidia or their pieces…. So what do you think it’s causing it…? Maybe the cables they tell you NOT to use…? If others users don’t use them and don’t have this issue… yeah, that’s a user issue. The user is being dumb and caused the entire issue.

            Don’t you think there is a reason why third party adapters and cables are always said to void warranty…? Because of shit like this, it’s the custom cable, not Nvidias issue with their card or adapter.

            Did he even try the tests without the cables…? Because I’m not seeing that.

        The cards aren’t affected* it’s the custom cables people are using.

        I wonder why he didn’t do a temp test without the extensions and just Nvidias adapter? Those parts aren’t hot and haven’t caused any issues from any reports so far. It’s ALWAYS had a custom extra cable. Increasing the length of cables increases power draw, it’s the basics of electricity. So yeah… increaseing cable length, and adding extra connections will make it waste more power and draw more…… it’s not surprising it’s only happening with systems with the extra cable length and connections that cause loss.

        Also, the headline is misleading, he’s blaming the cards, when the only piece that’s ever melted is custom non approved parts.
