What kind of power supply is needed for the rig?

[SilvKar]

Only 6 RTX2080Ti will consume around 2000W.

It turns out I need 2 power supplies, but which one do I need?

How much cooling is needed for this?

It's a good choice?

CPU: AMD EPYC 7252
MB: AsRock Rack ROMED8-2T
GPU: 6x RTX 2080Ti

It is recommended to use 80+ platinum, so feel free to mix and match any of your liking, unless you're building a server chassis then find the appropriate PSU that'll fit your chassis.

If the System needs 2000W you need a PSU-power of ~3000W.
