So I did some digging the non rtx ampere series cards are true 4.0 with no bus stepdown options usually only work with 11000 cpu or better (intel) ,
so a 5700xt for example is a 4.0 card but steps down 2.0 or 3.0 .
I could be wrong. I have a few of the crappy china 8 card units

I'll try to move a few to get my hands on this beauty any 110v options still?
