Did you simply swap the PSUs and keep the cables in place? If so PSU cables aren't really compatible with each other.

If you changed everything just make sure you have both the 24pin and 8 pin cables connected to your motherboard.

You could buy a cheap PSU tester tool like this https://www.amazon.com/Insten-24-pi...ds=psu+tester&qid=1554180343&s=gateway&sr=8-6 and make sure the actual PSU is good.

But other then a loose cable I don't know what else it could be. Did you hook up the SATA power to your drives?

Could be your new cpu is not supported by old motherboard or requires BIOS update before swapping cpus.

i7-9700k is not compatible with motherboard, your i5-6600k was working on.
You need a new Z390 motherboard.
