Question will new gpu fit in current case and new psu be good?

[kilo24]

will a zotac rtx 3080 trinity (10gb) fit inside my current ibuypower trace 2 case? according to my own measurements, the inside is 15.5" x 12.5" x 7". is a seasonic focus gx-1000 (1000w) a good psu for this and the rest of my build?

other specs revelant:
intel core i9 9900k cpu
adata 2x8 ddr4 ram
western digital green ssd

Just meassure the length as you have done and see if it will fit by that, also the PSU should be fine but Corsair is also a good option.
