A:Answer Hey I would recommend going to a website called pc part picker and uploading all of your parts. That will give you a good idea of the amount of power the 3070 would use as well as the rest of your rig. Overall I still think you may be pushing the psu a bit with a 600w. This is also off of the Nvidea webpage "Power Supply Requirements for Nvidia GeForce RTX 3070
Finally, for the Nvidia GeForce RTX 3070 PSU requirements, you'll "only" need 650W for Core i5/i7 & Ryzen 5/7 systems, 750W for Core i9/Ryzen 9 systems, and 850W for HEDT/Threadripper platforms."
