The GeForce RTX 4080 is already available on the market and the truth is that with this graphics card NVIDIA has not only achieved a significant jump in terms of performancebut also significantly improved values efficiency and was able to reach fantastic working temperatures.

To better understand everything that surrounds the GeForce RTX 4080 in terms of efficiency, without going into a complicated explanation, suffice it to say that it is more powerful than the GeForce RTX 3090 Ti and consumes 134 watts less (312 watts vs. 446 watts). Obviously, this will be recorded on the electricity bill and is also key to determining the power source we will need to move it optimally.

I know that, just like at the time with the GeForce RTX 4090, some of you still doubt about what power supply we will need to move the NVIDIA GeForce RTX 4080, which is why I decided to publish this article. I’ll also talk about other important details like the space it takes up in the chassis and the recommended minimum processor to get the most out of it.

You need a 750 watt power supply to power the GeForce RTX 4080

This means that the requirement drops by 100 watts compared to the GeForce RTX 4080, but the truth is that this recommendation is a bit inflated, because in reality, an average configuration would be enough with 700W power supply. The reason is very simple, this graphics card consumes 312 watts at stock frequencies, so with a team consisting of an Intel Core i5-13600K, 32 GB DDR5, two PCIe NVMe SSDs, an all-in-one 360 ​​mm liquid cooling kit and a GeForce RTX 4080, we would they had approximate consumption of 616 watts.

Obviously, if we have a configuration with higher consumption, such as a Core i9-13900K, or if we overclock, we will need a more powerful resource. For example, if we keep the previous configuration, but change the processor to Core i9-13900K and overclock the total consumption of the device could reach 770 wattsapproximately, which means we would need at least an 800 watt power supply.

Note that custom and overclocked models from some assemblers may require a slightly more powerful power supply. It is also important that it has a power supply three additional power connectors that use the 16-pin adapter that this graphics card includes, although as I told you in the analysis of the GeForce RTX 4080, two would actually be enough if we are not going to overclock.

Chassis space and processor: two recommendations

The GeForce RTX 4080 is a very large and bulky graphics card, just like the GeForce RTX 4090, so we will need a large chassis to mount it. Takes up three slots and measures 12″ longbut we also have to be careful when connecting the 16-pin power cable because in the first section of its route, we should not bend it excessively. If we do, we could have serious problems and the cable could overheat.

As for the processor, the GeForce RTX 4080 is a very powerful graphics card and, like the GeForce RTX 4090, it has a strong dependence on the processor at low resolutions. If we move below 2160p it’s easy to find yourself bottlenecked by less powerful CPUs, so the ideal thing to get the most out of it is to have a CPU with at least six cores and twelve threads and high IPC. A Core i5-13600K or Ryzen 5 7600X would be in the sweet spot. The Core i5-12600K and Ryzen 5 5600X would also be fine, though we’d notice a difference at lower resolutions and in CPU-bound scenarios.

When it comes to temperatures, don’t worry, the GeForce RTX 4080 is a very cool graphics card and it won’t become an “oven” inside your PC, Quite the contrary, because as we told you in our analysis, their working temperatures did not exceed 65 degrees at full load.
