  1. Hi guys I have been following the discussion, I am planning on a mini itx build using asus x570 I gaming, problem is it only has 1 pcie 4.0 16x that will be used for the gpu. It does have 2x m.2 M key slots (x4 lanes), I was planning on using a m.2 m key to pcie x4 adapter and run a riser to the HBA. My question is would a pcie gen 3 hba use the the gen 4 speeds? Most gen 3 hba are x8 so I would be running it on a pcie 4.0 x4 which although technically should have the same speeds I am not sure if the hba would use the full speed or simply it would just half itself. Another problem to think about is the m.2 m key to pcie x4 adapter... I see some pcie gen 3 ones but not gen 4 so wondering if the speeds will get throttled there or if simply the manufactures never bothered with put gen 4 compatible as it wasnt a "thing" at a home level. Would love some input on what you guys think?
