Question Gigabyte RTX 3070 low gpu usage.

[IstariLight]

Yesterday I bought these system:
CPU: i5 12400f
mobo: Asus Prime z690 D-4
GPU:Gigabyte Eagle RTX 3070
Ram:16gb DDR4 Fury 3200mhz
Problem is: im only getting 45-60 fps in Warhammer 40K : Darktide in 1080p, DLSS ON (automatic) , tried every dlss option and without dlss , graphic settings are high.
Tweaked every singgle graphic option but cant get higher fps than 60-65. Gpu usage in %39 maximum.
What can i do to get higher gpu usage? Please help me. Thank you.

I think the reason of the problem is the psu connector cables to the gpu.
