Which power supply for this RXT 4080 SUPER:

It’s perfectly logical to ask yourself the question of the power supply you’ll need to build a new configuration around this ROG Astral RTX 5080 OC Edition graphics card. To do this, there are several solutions, such as referring to NVIDIA‘s recommendations. In this case, NVIDIA recommends a minimum 850 watt power supply. On the Asus website, you can also find an online tool that lets you calculate the power you need to supply your configuration. All you need to do is specify the model of your processor and graphics card. This will give you a recommended power rating, as well as the option of indicating that you intend to overclock your configuration, which will increase the power of the power supply.

We’ve calculated the power required and this ROG Astral RTX 5080 OC Edition combined with our Intel i9-14900K processor requires a 850 watt power supply. If you want to overclock your system, Asus recommends a 1000-watt model.

With this, these units benefit from a particularly meticulous design. As you can see, they also have a small OLED display on the side that can be repositioned according to the orientation of the block.

Internally, the brand relies on quality components such as gallium nitride MOSFETs, which are claimed to be more efficient. Otherwise, GPU-FIRST technology will enable the block to supply power according to GPU activity rather than CPU activity. This allows better anticipation of power consumption peaks, for example. Naturally, cable management is entirely modular, with connectors featuring high-quality copper contacts.
