Question 1

What size power supply does the RTX 3060 need?

Accepted Answer

A 450W PSU is recommended for a typical build using the RTX 3060 (which draws about 170W), leaving ~30% headroom for the CPU and other components.

Question 2

Is a smaller PSU enough for the RTX 3060?

Accepted Answer

It can boot on less, but PSUs run most efficiently and reliably below ~80% load, so we recommend 450W rather than the bare minimum.
