Hey,

i installed the AS RockB450 Pro4 R2.0 with some RGB Fans i splitted the signal with this device to use the all:

It works as intended but when i shut off the pc the leds wont turn off. i disabled [Turn on Led in S5] now when i shut of the pc the leds als turn of. So now the weird part, with those settings the pc wont turn on again it only will turn on after i pulled the plug out of the wall. If i enable turn on led in S5 the leds wont turn of but im able to normally start the pc via pressing the power button.

And the FAN which is connected to the CPU_FAN1 just keeps spinning after the pc is shut down.

need held pls :D
