Is this safe or not

And will it support a 3070 maybe

Safe? Maybe. Good? No. I'd add 200W for efficiency if nothing else. Your power supply will be most efficient if you plan for it to be at around 50% usage. it starts to drop off the further you get from that. Of the top of my head, I want to say 20% in either direction of that is still pretty good, but I haven't looked in a while.

So no ?

For a 3000 series GPU: definitely no. Nor for anything comparable from AMD. But an APU (CPU+iGPU), 650W is way more then it needs.

This literally does not matter. The power supply is rarely most efficient at 50% regardless, and is generally the same from 20% to like, 90%.

So will it be fine with a 2060 and if so will it burn my house down

I just need to know if it is safe or will burn

More on the bias of burn, cooler master beyond masterwatt maker 1200 is kinda sketchy.

Don't cheap out on a PSU, they will last years if you get a good one. For example the BeQuiet straight power series is good. For that PC 600W should be enough, if the 750W is like 10 bucks more get the 750W.
