If you are thinking of buying a GeForce RTX 4070 but you are not sure which power supply you need, don’t worry, in this article we are going to tell you everything you need to know so as not to be wrong. Before going into the subject, it is important that you take one thing into account, and that is that depending on the version you are going to buy you will need to have one or two wires additional 8-pin power supply.
Versions of the GeForce RTX 4070 that use the 16-pin connector come with an adapter that requires two additional 8-pin power connectors, and this includes the Founders Edition model. However, we can also find models with personalized designs that only use an additional 8-pin power connectorand that do not make any kind of sacrifice either in terms of performance or stability.
So, for example, the GIGABYTE GeForce RTX 4070 WindForce OC we reviewed at the time only uses an additional 8-pin power connector, even though it comes with a slight overclock over the reference model. However, the GIGABYTE GeForce RTX 4070 GAMING OC uses the 16-pin power connector, and requires two additional 8-pin power connectors.
In any case, the important thing is that the differences in consumption between the different models are minimal, and therefore we will not have to buy a more powerful power supply, since in the end the minimum requirement will remain the same. You just have to be careful to make sure that you have the required additional power connectors, especially if you are going to buy a model that uses the 16-pin connector.
You will need a 600 watt power supply
Although this It will largely depend on the configuration of your PC.because the GeForce RTX 4070 registers maximum consumption peaks of around 200 watts, and this means that if you have a very low consumption configuration, said graphics card could work without problems even with a 550 watt power supply.
On the contrary, if you have a configuration with a very high consumption, it is possible that this 600-watt source is a bit tight, although obviously this will not be normal because we have a margin of 400 watts, and current processors that reach consumption peaks of 300 watts can be counted on the fingers of one hand.
Regarding chassis space, keep in mind that not all models are equally large, not as wide. The GeForce RTX 4070 Founders Edition is undoubtedly one of the most compact versions, occupying only two expansion slots and measuring 24cm in length. In contrast, the ASUS TUF Gaming GeForce RTX 4070 OC is one of the largest, occupying three expansion slots and measuring 30.3 cm in length.
I leave you two power supply recommendations economic that will allow you to move a GeForce RTX 4070 without problems. If you have any questions you can leave it in the comments and we will help you solve it.
- Thermaltake Smart RGB 600W 80 Plus for 49.99 euros.
- NOX HUMMER X600W semi-modular 80 Plus Bronze for 66.88 euros.
In rasterization the GeForce RTX 4070 performs more or less at the same level as a GeForce RXT 3080, but it is more efficient and offers more interesting value thanks to the support of DLSS 3 (frame generation). It does not reach high temperatures (it stays below 70 degrees), so you will not have to worry about the heat generated in the chassis. To get the most out of it, it is a good idea to accompany it with at least one Ryzen 5 5600 or an Intel Core i5-11400F.
