I am building a ryzen system, I’ve got every component but the cpu. Im trying to power on the motherboard so i can see if the fans spin up on my cpu cooler and graphics card (not looking to boot). But when i short my motherboard nothing happens (should have power running trough it). So im wondering if i can run power trough my motherboard without the cpu, does anyone know? Im worried my motherboard is broken.

Motherboard: Gigabyte B450M DS3H AM4
