What kind of power supply should I use when the power consumption of RTX 4090 reaches 450W?NVIDIA explains it

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.

First of all, the type, RTX 4090 and RTX 4080 are both equipped with 16-pin power interface of PCIe 5.0 graphics card this time. This is a high-power power supply interface designed for ATX 3.0 power supply.Graphics cards that support 600W power consumption, NVIDIA said this power supply will also be available in October.

However, the 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, and 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, and 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, but AMD's Ryzen 7000 andIntel's 13th-generation Core will be on the market. 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. I personally recommend that a power supply of 1000W gold or above is more secure.

According to NVIDIA's introduction, the RTX 40 series graphics cards have been optimized in terms of power supply. There are not too many power fluctuations like the previous RTX 3090. The peak power consumption is relatively stable this time, and the pressure on the power supply is less.
