NVIDIA responded to the most frequently asked questions about the feeding of the new GeForce RTX 40 series graphic accelerators. In particular, NVIDIA revealed more details about the complete transfer devices needed to connect the new video cards to the old power supply units.

The GeForce RTX 40 series does not require the use of new power units meeting ATX 3.0 and PCIE 5.0 standards. The most important requirement for the power unit is its capacity. Thus, for the flagship video map GeForce RTX 4090, NVIDIA recommends the use of a 850 W BP. The declared energy consumption of the accelerator itself can reach 450 W. For the GeForce RTX 408016GB models, NVIDIA recommends the use of power units of 750 W and 700 W respectively.

The GeForce RTX 40 series is equipped with a new 12+4-activated PCIe 5.0 standard 12VHPWR. For compatibility with old power supply units that do not have power cables with a new converter, the NVIDIA has provided a set of four standard 8-point interfaces for the new 12VHPWR.

The company itself calls it "smart." It is compatible with the ATX 2.0 standard and is equipped with an active converter that translates the signals from the old power unit into the corresponding signals for the new split of the PCIe 5.0 standard.

The manufacturer adds that for GeForce RTX 4090 and GeForce RTX 408016GB, at least three standard 8-point interfaces are required to enable the transmission of 450 W of power, but it is better to connect all four cables to the switch, especially if the GPU is to be accelerated.

NVIDIA indicates that the transducer has a declared 30 connections/disablements, which is standard for PCIE/ATX Connectors. The company recommends that 36 mm of free space be left above the video map at the location of the transferor for its convenient installation and permissible bend.
