Question System wont boot when I connect my second gpu

[Zaul718]

Recently bricked my b450 so bought a new gigabyte mobo x570 installed my rtx 2080 and it boots fine, but when i add an rtx 2060 for 3d rendering it does not boot. I ve changed bios csm to uefi (a solution i found on this forum) and it boots but to bios and a limited bios is visible rest blacked out. Can anyone help?
i have a 850w pwr supply, i had the exact setup in my previous mobo to and it worked.
i use my pc for 3d animation etc not gaming.
