I read your shopping list, there's has two problems, the motherboard and power supply, the power of one 3090 is 350 watts, and the power of four is 1400 watts, so your power supply should be at least 2000 watts (The specific calculation will be made after the CPU is determined), the problem with the motherboard is that the b650 does not support four 3090 video cards, and it only has two videos card slots.😉

I think the thread rapper 5990x is better, the mainboard you can uses supermicro server motherboard, I have a computer using amd 5950x and a 3090ti, the mainboard is x570, if you use 4x 3090, it is best to use a server mainboard, for stable and performance.😉

Well, I’m not sure how feasible the method of two power supplies for one host is😂, and it’s still a problem with the motherboard. I can’t comment on the stability of the method of connecting four 3090s using graphics card expansion (because I haven’t done so yet), I think you should carefully consider your plan, the cost of trial and error is not low.
