With the launch of the new card, players still have a question to pay attention to, that is, what power supply should the RTX 40 series use? The NVIDIA official community also responded to this question a few days ago.
The first is the type,The RTX 4090 and RTX 4080 are both equipped with 16-pin power connectors for PCIe 5.0 graphics cards this time.This is a high-power power supply interface designed with an ATX 3.0 power supply, which can support graphics cards with a power consumption of 600W. NVIDIA said that this power supply will also be available in October.
However, ATX 3.0 power supply is not necessary.RTX 4090 and RTX 4080 graphics cards can still support the 8pin power supply interface through the interface, the current power supply can still be used.
The second question is how much power is needed.NVIDIA officially recommends RTX 4090 graphics card with 850W power supply,RTX 4080 16GB with 750W power supply, RTX 4080 12GB only needs 700W power supply.
However, NVIDIA’s power recommendation is based on the Ryzen 9 5900X processor platform, and its TDP is only 105W, butAMDThe Ryzen 7000 and Intel 13th-generation Core will be launched. Players who buy new cards are more inclined to choose a new generation platform, and the power consumption of the processor will also be greatly increased. The more realistic PL2 power consumption is generally above 200W.
Therefore, if high-end players use a new generation of graphics cards and processors, the power supply can still be appropriately expanded.Personally, it is recommended that a power supply of 1000W gold and above is more secure.
According to NVIDIA’s introduction, the RTX 40 series graphics cards have been optimized for power supply. Unlike the previous RTX 3090, there are too many power fluctuations. The peak power consumption is relatively stable this time, and the pressure on the power supply is less.
