NVIDIA has released a new generation of RTX 4090/4080 graphics cards, upgraded Ada Lovelace architecture and TSMC 4nm process, as well as a new RTX chase architecture and DLSS 3 new technology, gaming performance up to 4 times the previous generation of graphics cards. This time, as usual, NVIDIA launched the RTX 4090 Founders Edition, the official NVIDIA version of the graphics card, only the scale is more than before, reaching 3.5 slot thickness.
In addition, NVIDIA has further introduced the RTX 4090 graphics card PCB, the entire design is similar to the previous RTX 3090 Ti, the power supply design is particularly luxurious, equipped with a public version of the card’s unprecedented 23-phase power supply, including the GPU core power supply 20 phases, memory power supply 3 phases.
Usually, the more phases of power supply, not only higher output power, but also can share the load and reduce heat, and NVIDIA also stressed that the RTX 4090 power supply has been optimized, no longer have a sharp peak voltage, current, from the official graph, the RTX 4090 power supply curve under high load is very stable, unlike the RTX 3090 graphics card as frequent fluctuations.
Many people do not understand that for the power supply, graphics card power supply is not just to see the power consumption high or low, stability is more important, if the current and voltage fluctuate frequently, the pressure on the power supply is greater, RTX 4090 graphics card this time on the power supply should be more friendly.
In addition, the RTX 4090 graphics card uses a 16-pin power supply interface in PCIe 5.0, but NVIDIA says it does not necessarily need an ATX 3.0 power supply, there are 8pin to the interface, which can be applied to any power supply.
