How to properly assemble the 12VHPWR connector
-
In this post, they explain that if instead of soldering the pins of the 12VHPWR connector, they are crimped, the problems of excess temperature in the GeForce RTX 4090 disappear.

First, direct soldering is a mess. Second, you can crimp and then solder the crimped area, making that section more homogeneous. This has been done for years in high-consumption equipment.

I find it terrifying that in a multimillion-dollar industry like this, with a product of nearly 2000 crushers, no one has had the idea to say let's do a test run to see if this explodes or what. And that it has to come from an independent media outlet to say that creating hot spots in power lines that are at the limit of the design is a mistake that is better to crimp. This is one more proof of how rotten the industry is and the blowout that is going to happen. -

From my ignorance, what difference does it make if the cable is soldered to the connector directly or soldered to an intermediate element, if the connections between male and female are terrible?

@clipper What palotes says.
I've seen it in repairs of the ground clamp of arc welders, it welded to the cable very well, and it didn't last even half an electrode jjj.At high currents the relative electrical resistance of the weld produces a hot spot, and the hotter it gets the more it increases the actual resistivity of the weld material (thereby causing more heating).
You may experience less power reaching you, or even that it melts and dances during the sessions depending on the weld material.
It depends on the sizing of the line, if it's just right as they say, this can happen.A basic tip for users of those connectors is that carrying the board very hot favors this to happen, simply because the connector dissipates mostly through its legs across the board.
And the other is that having the connector in front of some air current can also take away a lot of heat, and it can be something simple to achieve.Salu2.
