Is 650W enough??

[TheMysticalPotato]

Hey its my first time here so sorry if Im posting in the wrong place, but I need some help because Im kind of at a loss. 
So some backstory: I built my system about 5 years ago and its gone through some changes. Right now it has an i5 7400 and a 1060 6gb with a Corsair (green) CX 430 PSU. I now know my PSU choice was not the best but hey, it lasted me through all these years.
Lately, with all the staying at home, Ive been using my PC more and more and Ive noticed some really annoying sounds. The worst is the CPU cooler but the PSU has started making some noise as well. Since Im planning to upgrade with the next gen stuff I thought why not upgrade the "secondary" components in the mean time. I got a Hyper 212 black for the CPU and a Super Flower Leadex III 650W Gold to replace the PSU. The thing is, I've seen the leaks claiming the RTX 30 series could be really power hungry so Im wondering if the 650 watts will be enough or if I should return this unit to buy a more powerful one. I dont think Im going for the top of the line 3090 or 3080 so maybe it would be enough?
Im just looking for some advice from someone who knows better.

Thanks everyone!

Even if you end up with a 300W GPU, a 650W power supply will be sufficient. It's a good wattage to go for.
