Table of Contents

Whether you are building a new PC or upgrading an existing one, choosing the right PSU is crucial for ensuring a stable and efficient power delivery to all of the components. This is especially true if you have a new and high-performance GPU such as RTX 4070 Ti. Choosing the right PSU for the 4070 Ti is fairly simple, however, we recommend you to have some headroom, future proofing your system to some degree.

What PSU do you need for the RTX 4070 Ti?

Generally speaking a 650W750W PSU should be all that you need but you should really consider going for an 850W +, and here is why. The RTX 4070 Ti will only use around 300W of power, which when added onto the other system requirements means you would easily manage power with a 650W PSU. So, yes 850W is overkill, however, PSUs are rated to last a very long time, so you should always consider what your PC specifications may look like further down the line.
