gen5

Can someone tell if i can put a Gen5 SSD for example the Crucial T700 on my Z690 AORUS ELITE AX ? From what i know supports Gen4 And if i do, will i get the full speed of the T700 ?

I feel like an idiot for making this inquiry, but I’d rather not make a silly mistake. I’ve recently collected the parts to build my new computer and I was wondering exactly which slots my RTX 3090 and samsung 980 pro should go on my Asus ROG strix z690-e. I thought the GPU should go in the top...
