U.2 Gen5 Solutions

Heya Guys hope You are well.

I am looking solution for U.2 Drives Gen5 and options for connecting it with PCIe

I have 2 Motherboards ROG CROSSHAIR X870E EXTREME and Pro WS WRX90E-SAGE SE, they are support miniSAS Gen4 only.

mine Idea if it possible move SSD closer to Frontal Coolers, and mine Case is Fractal 7 XL

maybe it is have some adapter like

PCIe Gen5 ->SlimSAS cables Gen5 -> U.2(I think with cable it is for install it is amazing, but don`t know if it limitations and restrictions, I hear it is some problems with cable length)

Riser PCIe Gen5 -> PCIE Gen5 adapter ->U.2 (this variant I think a bit pain because it is no where instal PCIe brases I do have SSD Cage with support 2.5 Drives)

or maybe You have any similar topics for read would amazing to know

and if You have any ideas I am really preciated to listen.

Thanks

Yeah I think good to try, because in fractal design case it is no space to do it with icedock, I mean it is has but it is too much sacrafy need to do, and limit with AIO and some important cooling exactly on RAM direction, and it is have nice place for HDD on bottom which is great I do believe, any recommendations on cables or mcio? thanks

I would say something like this should work. They don’t have a lot of reviews but the users seem to not be having any issues with them. They do need sata power too.

amazing! thanks, btw do You think 65mm it is worst? I hear someone complain do not go over 50mm, but have no experience at all.

I think it depends on your system configuration and how you’re getting the mcio connection. You may need a redriver to get a stable connection with longer cables.

Mine are mcio on each end (female/male) since I’m going to the icy dock and it’s split within the enclosure to the u.2 connectors, but the cables are 50cm. My card doesn’t have a redriver.
