KEYBOARD LED'S/RGB STRIPS light up when i flip the PSU switch on, but before pressing the power button on my PC.

I have no issue with my build, but I've noticed when i first put it together, when i turn the PSU switch on before I press the actual power button on my PC, the RGB strip and my Corsair k70 rgb LED's lights up. Any idea why that would be?

Specs:
i7 9700k
MSI GTX 1080 TI GAMING X
T-FORCE 16GB 3200 MHZ
AORUS Z390 PRO WIFI
CORSAIR RM850X PSU

This is beause your motherboard switches on before switching off. It is normal for most motherboards

Alright just making sure, I just recently upgrade and my previous build (2015) didn't do that and I just wanted to get a second opinion on it to make sure nothing was wrong, but i appreciate the replies! @Faisal A
