I have a few Corsair KB's, I normally turn off the RGB personally. My main KB is the Steel Series APEX Pro.

Nope, just takes some basic knowledge and maybe reading or watching some PSU reviews now and then.

HX 1200 Without a doubt.

Yeah, it's only RGB Lighting.

An 850W PSU is not overkill. There is no such thing as overkill, that word is vastly over used and misused these days. Even a 1000W PSU for your system is not even close to out of bounds.

I'd like to know who this supplier is that made that statement.

That's not strange at all really if you know history. That's how AMD got started, making CPUs for Intel.

Likely thinking about the AX, that is Seasonic Based.

We can always ask @jonnyGURU he would know.

No, not a good idea at all. Leave the GPU in the box until you get a new PSU.

If it was my money I would go with the HX1200 out of that list with the RM1000I next.

Makes since. Professional testing equipment vs NOT professional testing equipment. Sometimes it takes a REAL COMMENTMENT as in REAL money to do it correctly. Or do it right, or just don't do it at all. Not just shooting video with their smart phone their mom got them and shooting video in their mom's basement with $20 equipment and free software and thinking they are doing something. Even worse people actually believe it.

Yeah, I seriously doubt there are any shortcuts cost wise in measuring ripple and other things when it comes to PSUs. Like people getting those $20 Kill-Watts and thinking they mean something. Might be good for a desk lamp or something.

Ideally yes, something from Tier A or B.

The RM850 is fine.
