I am building a new PC with the B450 Aorus Pro WiFi, and the machine all put together shows no signs of power.
To troubleshoot, I plugged in the 24 pin and CPU power into an old working tower, and not only did it power on, but the fans inside the new case (that I forgot to unplug) powered on as well. Replacing the cables back into the new mobo gives the same result as before: no sign of power.
What may be the cause of this? Is the mobo dead on arrival? Or is there something I could've overlooked?
Known working parts:
Rosewill RGB fans x3 and RGB controller
Corsair 650W semi-modular PSU
Powercolor R9 380 4GB
WD Blue 2TB HDD
SanDisk 250GB SSD
Unknown:
Gigabyte AORUS B450 Pro Wifi
AMD Ryzen 7 2700X
AMD Wraith Prism Cooler
Ballistix Sport 2x8GB 3200Mhz RAM
Deepcool Matrexx 55 Case
