The high-end graphics cards built on the most contemporary architecture have now been announced by both GPU makers and partially released.
ASUS has revised its list of recommended power supplies for the first four NVIDIA Ada Lovelace and AMD RDNA3 GPUs. The suggestions are quite precise because none of this information is hidden anymore and ASUS is actively marketing or developing bespoke designs based on each architecture.
Officially, NVIDIA recommends a minimum 850W power supply for its RTX 4090 GPU, the series’ top model. AMD’s suggestion is lower, and the company thinks an 800W PSU should be enough. Although the central processing unit (CPU) is the most energy-intensive part of the system, other components should also be considered when making PSU recommendations.

The 750W PSU should be adequate for RTX 4080 and RX 7900 XT cards, while the 850W PSU should be acceptable for mainstream systems with Intel Core i5 or Ryzen 5. However, those recommendations are stronger with Intel Core i7/Ryzen 7 and Core i9/Ryzen 9 processors. For the RTX 4090, ASUS suggests no less than 1000W of power, while the Radeon XTX requires between 850W and 1000W.
Additionally, the business is recommending the AMD Threadripper series and Intel HEDT processors. In this case, both GPUs should be connected with a PSU of at least 1200W. The RTX 4080 and RX 7900 XT cards are expected to work with 750W and 850W power supplies, respectively; the latter is recommended even for high-end systems.
The RTX 40 series features the new 16-pin PCIe Gen5 power connector, which is not mentioned in the document. Therefore, it is appropriate to consider the ASUS ROG Loki line of power supplies, which are ATX 3.0 and have native implementations of 12VHPWR connections. The rest of AMD and NVIDIA’s new lineups have yet to be confirmed, so no more suggestions were made.
