I finally upgraded from my i5 2500 to Ryzen today. But now my PC won't power on at all (fans not spinning, LEDs not lighting up).
My 24pin and 8pin connectors are plugged in. My PSU switch is on. My PSU works (worked 3 hours ago on my old system). My PSU is connected to an outlet.
I've tried shorting the power button connector but even then nothing happened.
I can't figure out what I did wrong.

Edit:
Specs:
  • Ryzen 5 2600
  • AsRock AB350M Pro4
  • 2x8 GB DDR4 3000 Corsair Vengeance
