parece cada vez más claro que el problema en las 4090 es del cable adaptador proporcionado por nvidia que no es de la calidad adecuada:
https://www.igorslab.de/en/adapter-of-t ... reakpoint/"The problem is not the 12VHPWR connection as such, nor the repeated plugging or unplugging.
Standard compliant power supply cables from brand manufacturers are NOT affected by this so far.
The current trigger is NVIDIA’s own adapter to 4x 8-pin in the accessories, whose inferior quality can lead to failures and has already caused damage in single cases.
Splitting each of the four 14AWG leads onto each of the 6 pins in the 12VHPWR connector of the adapter by soldering them onto bridges that are much too thin is dangerous because the ends of the leads can break off at the solder joint (e.g., when kinked or bent several times).
Bending or kinking the wires directly at the connector of the adapter puts too much pressure on the solder joints and bridges, so that they can break off.
The inner bridge between the pins is too thin (resulting cross section) to compensate the current flow on two or three instead of four connected 12V lines.
NVIDIA has already been informed in advance and the data and pictures were also provided by be quiet! directly to the R&D department."
