Are you someone who frequently disassembles your computer or replaces its graphics cards? Well, you will have to pay attention to the PCIe 5.0 power cord adapter that may be necessary to connect the NVIDIA GeForce RTX 4000 cards. As ZOTAC mentioned, a 4x 8-pin – 12VHPWR (also known as PCIe 5.0 / 16-pin) power cable could have a service life that Throwed in chests with circles is limited to… 30 connections/classes only.
The limitations of a 12VHPWR adapter can shock you and it looks like you’ll have to be very careful about it. It’s worth keeping this in mind when buying any new generation GeForce, not just ZOTAC.

As you know, this adapter will be included with almost every new graphics from NVIDIA. All this to maintain compatibility with existing energy sources. However, these strict restrictions on the adapter can be shocking and it seems that you will have to be very careful with them. It is possible that this note applies not only to adapters from ZOTAC, but also from other manufacturers. Interestingly, the problem of the failure rate of 12VHPWR power cables has been widely known for some time.

Already in the following PCI-SIG chips you can find descriptions of 12VHPWR cables that are prone to hot spots or even melt due to excessive bending or excessive contact cycles. The source says up to 40 connections/disconnects, so the 30 number set by ZOTAC can be assumed to be an underestimate just in case prosecution is avoided in the event of potential problems. Well, anyone who buys a GeForce RTX 4090 graphics card from ZOTAC should be very careful with the adapter included. So far, information about the possible high failure rate of cables is not available on the websites of other manufacturers, but it is worth keeping this topic in mind when buying any new generation GeForce.
