The 650W PS probably won't run out of power for your build, but for stability and longevity, you don't want to run a power supply anywhere near its limit.
At least a 750w PSU for a 2060 and an i5?
Nothing wrong with using one it but it's not in anyway needed. Stability? Somehow a rig that can only draw 400ish watts with the GPU and CPU running a stress test when OC'd is going to be more stable if you have more wattage available? No, you'll have better stability and reliability with a low ripple/tightly regulated unit but adding moar wattz isn't going to do anything.
As for the build there's nothing wrong with what you've picked other than a few things:
I'd opt for a Seasonic Focus 550w unit, often you'll see the 650w version for $5 or $10 more but it's not necessary by any means.
You could also get away with a cheaper SSD, they've come far enough that you're not going to notice much difference between them on a gaming rig where you only need to worry about loading times and maybe boot time.
Not sure where you're shopping but the ram you picked was $130 on newegg while this is -$10 while it's on sale:
I think I'd go with a 1070TI for the extra VRAM as it would make a much better 1440p card. Nothing wrong with 1080p but upgrading to 1440p/144hz IPS was the single best upgrade I've ever done. Plus Nvidia nerfed the 1070TI by forcing all AIBs to keep the same clockspeed so it wouldn't be as fast as a 1080. That means you can use Nvinspector to add +100mhz or so to the core and set the clocks as a start up task. No gaudy overclocking software running all the time that way, plus I get better results using it than anything else and it's something most people would have installed anyway if they have an Nvidia GPU.
