The 12VHPWR Failure
Various incidents have taken place where users are facing burnt RTX 4090 adaptors. Igor’s Lab states; Igor states that the issue arises not due to the cable bending or excessive temperatures. Rather, the cable is built with poor quality material which leads to such issues. The main issue is in the engineering design of these cables. ~Igor’s Lab
AMD Dropping the 12VHPWR Adapter
2 days ago, Kyle Bennett posted on Twitter that AMD’s next-gen RDNA3 GPUs will not make use of this adapter. ~Igor’s Lab This is a major news because this adapter has some fundamental issues as described by Igor’s Lab; ~Kyle Bennet
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.
