12VHPWR adapter for nVidia’s GeForce RTX 4090 – Two manufacturers, contact problems

Citiraj:

Astron is the leading manufacturer of the adapter (x4 and x3), NTK is also a Taiwanese company and quasi also a direct competitor of Astron. The first difference is the nose of the lock. Purely subjectively tested and after the blind tests with third parties, the plug from NTK latches better. Both in terms of the tactile feel and the slight acoustic clicking noise. It is also easier to detach, which definitely increases usability and operational reliability. The second difference is in the spring contacts used. Astron uses spring contacts with two slots, NTK only one. The adapter provided by nVidia should only be considered a stopgap solution in any case. To what extent Astron can be blamed for the whole mess is something I cannot and will not judge. Ultimately, nVidia and its supplier will have to settle this among themselves. The PCI SIG has to be blamed for setting up standards for connections that are neither field-tested nor do they take into account the possible interactions of the different influences up to the end user. On the other hand, the x4 adapter from Astron is a real complete disaster, also and especially when it comes to craftsmanship. I now only use the NTK adapters privately and have not had a single failure with them.

RTX 4080 appears to be 19% faster than RTX 3090 Ti PGF (the flagship ZOTAC model) and round 23% slower than RTX 4090.
