My first custom build. I have the cpu, mobo, psu, and case and I wanted to see what the fans are like and stuff. In theory, the mobo should turn on without ram or a drive installed, but it isn't. MŠI B450 CARBON PRO MAX WIFI for reference. 24 pin, sata power, case pwr sw, cpu power without the extra 4 pin is connected, psů switch is on, sockets work, switches on the sockets work, I'm kinda lost. No fans spin not even on the psů. Nothing to test the components with. Do I have a bad mobo?
