I have nearly the same motherboard than yours. You should update your BIOS to version F15a.
It's missing in your ACPI folder two SSDT : SSDT-EC, SSDT-PLUG. And the OpenCore team recommends to not use a DSDT.
Your DeviceProperties is incomplete.
You should delete NullCPUPowerManagement.kext and USBPorts.kext and add WhateverGreen.kext.
I join my config.plist for helping you.
