Just built a new system:
Fractal R6 USB-C Case
Corsair HX 1200 PS
Asus Crosshair VII Hero
AMD 2700X
AMD Vega 56 (displayport being used)
16GB Corsair RAM (on MB compat list)
2 x M2 drives
1 HD (backup drive, data to be restored to system upon completion)

Upon PS set to 1: MB RGB lights turn on

Upon power initiation via case:
Case fans initiate
Memory, Vega RGB light up
Legacy DVD spins up
Keyboard (caps lock lights up/off) on press
Power-on button (Start) on MB stays Red
No sound through Front panel audio connector (10-1 pin AAFP)
No display (hence no bios)
AE code displayed on the MB Q-Code

System has no OS (obviously)

Thoughts?
