NVIDIA recently released the RTX 4090 and RTX 4080 16GB, RTX 4080 12GB three graphics cards, doubling the performance of the previous generation of graphics cards, DLSS 3 and RTX additional into even 3-4 times the performance, of course, at the cost of power consumption has also increased, RTX 4090 450W power consumption than the previous generation increased by 100W.
NVIDIA’s official community has also responded to this question.
The first is the type, RTX 4090 and RTX 4080 this time are equipped with PCIe 5.0 graphics card 16-pin power connector, which is designed with ATX 3.0 power supply and high power supply interface, can support 600W power consumption graphics card, NVIDIA said this power supply will also be listed in October.
However, ATX 3.0 power supply is not necessary, RTX 4090 and RTX 4080 graphics cards can still be achieved through the transfer interface to support the 8pin power supply interface, the current power supply can still be used.
The second problem is how much power is needed. NVIDIA officially recommends the RTX 4090 graphics card with an 850W power supply, the RTX 4080 16GB with a 750W power supply, and the RTX 4080 12GB with only a 700W power supply.
However, NVIDIA’s power recommendation is based on the Rex 9 5900X processor platform, whose TDP is only 105W, but AMD’s Rex 7000 and Intel 13 generation Core are coming to market, and players buying new cards are more inclined to choose a new generation of platforms, and processor power consumption will be significantly increased, with more realistic PL2 power consumption generally above 200W.
Therefore, for high-end players, if the new generation of graphics cards and processors, the power supply power can still be properly extended some, I personally recommend 1000W Gold and above power supply is more secure.
According to NVIDIA, the RTX 40 series graphics cards are optimized for power supply, unlike the previous RTX 3090, which had too many power fluctuations, the peak power consumption is smoother this time, and the pressure on the power supply is less.
