Feels like a thermistor would be a good safety device to add to those connectors…

yes, by all means, add additional components, complexity and digital logic to detect the overheating of an underspecced component, that sound much more reasonable than using a connector that can carry the required current without heating up.

  Let's add some IOT wifi-connected temperature sensors with RGB LED

    That will sell. What a wonderful idea!

      In fact let's forget the temperature thing and just do the RGB leds.

        Who needs LEDs when you can dual-purpose the power connectors and just run enough current to make them glow?

        Hmm, but that will only get us red, and if we're persistent enough, white. That's not good enough for RGB!

        Shouldn't we be able to get all colors except pink ?

        The color a black body emits at certain temperatures follow the planckian locus (https://en.wikipedia.org/wiki/Planckian_locus https://en.wikipedia.org/wiki/Planckian_locus). The only saturated primary color on that curve is red.

        Let’s add a propane torch in there so we can get an authentic blue color!

        And we would have lngctl to control the flow rate. Occasionally crashing and leading to fires.

Even easier to use the old standard instead of making a new solution to a problem that didn't exist in the first place (except for aesthetic reasons). The old connectors were solid and had plenty of headroom if used within spec, with the new cards you'd still just need 3-4 to be well within spec - no monitoring circuitry needed.

  Old bad, new better.

  The PCI-SIG maximum safe rating for the old and janky 8-pin connectors was 150 watt, despite how bulky it was. The 4090 would need 4 of those (5 if you account for when it exceeds 600 watt). A new connector was absolutely necessary, even for more reasonable GPU power levels. That the current connector is broken is a different problem, and could likely be fixed without manufacturing changes without a new overall connector design.

    Then when they redesign the spec they should have made the connector they used larger. There's a problem with running 600 Watts through that connector, if this fire thing is regular issue it's going to burn someone's house down or kill someone
    - arghwhat 4y ago
      They could have made it even smaller. The problem is not at all the size, it’s just bad contact.
      - bioemerl 4y ago
        Bad contact shouldn't be an issue. You should have to be hilariously and obviously bad with the contact in order for it to be a problem. If slightly bent cables are the problem, it's clear that your cable is rated far too high for what it is and you need to mandate larger conductors or more conductors carrying less current so that there is no chance it burns unless the cable is very badly damaged or misused.
