According to Gigabyte, next-generation graphics cards will require a new 16-pin power cable or converter to meet current PCIe 5.0 criteria. In October, there was a lot of talk surrounding NVIDIA’s new GeForce RTX 3090 Ti graphics card and its next-gen technologies. One of the standout features was the latest PCIe 5.0 technology, which provides twice the power of the previous PCIe generation.
The PCIe Gen5 standard is a new high-speed serial computer expansion bus. The Gen5 16-pin power cable replaces current 8-pin power cables that can produce up to 150W with a single 600W connection. For power delivery, the cable requires 12 wires, and for signal transmission, it requires four data pathways. The four data routes ensure that the connection is secure, and the graphics card will require more energy than the original 450W. The power supply unit will only produce 450W of electricity or less if the data signals are missing.

For the standard current of power, Gigabyte has confirmed that PCIe Gen5 compliant graphics cards will use a single 16-pin power cable or 3×8-pin to one 16-pin cable connector. No one has heard of an adapter in creation for the PCIe 5.0 connections. There will be both the 16-pin cable connector and a three 8-pin to 16-pin adapter for full compatibility with PCIe Gen5 standards, which is interesting. Gigabyte does not mention the 12+0-pin cable or the newer 16-pin cable in the statement, which could mean that the adapter allows for the transmission of data signals.
PCI-SIG, the body that defines and maintains the various PCIe standards, has kept details like power specifications under wraps, leading to more speculation about the discrepancies between the NVIDIA 12-pin and the PCIe Gen5 12+0-pin. While the two are confirmed to be compatible, the quantity of power that flows through NVIDIA’s cable is unknown.
