Which power supply do I need for RTX 3080?

Last updated:

Generational releases have increased the power requirements of components, so you may be wondering what power supply do I need for 3080? The Nvidia RTX 3080 came out in September 2020 as a huge success, flying off the shelves but also suffering from shortages. This means that although players were hungry for them, it was mainly scalpers or crypto miners who ended up with them instead.

However, with the recent crypto crash, there has been some good news for the average computer user. Since many cards are swapped out and the overall need for them is falling, there is plenty of supply. As well as the price of GPUs returning more or less to MSRP. While the choice between AMD Radeon and Nvidia is disproportionate, you may have made your choice on 3080.

With this new 3080 you need a good power supply to keep it running. Here we see what you need to meet his needs. As with the performance behind it, you want to make sure you don’t lose performance with your new card.

What PSU do I need for 3080?

There are now several versions of the 3080, so let’s take a look at the original RTX 3080 10GB first. This card was released with a graphics card power of 320W. For this, Nvidia recommends a 750-watt power supply, but for a system with an i9-10900K processor and Founder’s Edition card. So if you have a much more powerful CPU and more additions to your build, you might need more.

Now there’s also an RTX 3080 12GB version, a newer addition to the lineup. Will be released in 2022, about a year and a half after the original and offers more VRAM. Which in turn increases the power consumption of the card by 30W up to 350W. However, the performance jump does not increase the required system performance, according to Nvidia, which still suggests a 750 W power supply.

Most recently, the RTX 3080 Ti is an even better version. When comparing the 3080 to the 3080 Ti, there is a switch in GPU to a fuller variant. Along with more memory giving it better bandwidth. And similarly, with the higher power, it also increases the required power to the same as the Ti. With the 350W TDP, it also only asks for a 750W PSU.

Will a 750W PSU be enough for the RTX 40 series?

With a recommended power supply of 750W for two quite powerful components. However, according to rumors about the RTX 40 series, this may not quite be enough for the next generation of cards. The latest rumors suggest that the RTX 4090 has a TDP of 450W, the RTX 4080 has a power of 420W and the RTX 4070 has a TDP of 300W.

That means if you were planning to buy a 4080, it might have 100W more power than the 3080. This, in turn, may result in Nvidia recommending a 100W higher PSU, bringing it up to a recommended 850W PSU . Only the 3090 Ti with 450 W currently comes close to this TDP, for which Nvidia recommends an 850 W supply. So it may be the same case if the 4080/4090 actually have their rumored board power.
