I have just built my first pc, and after turning it on, everything runs... except the ports. This includes the ports on the case itself, and the ports that are on the motherboard. This means that when I connect the hdmi cable from my monitor to my pc nothing happens, the monitor just says "no signal - entering low power mode" and turns off. As far as I can tell, the problem is that the usb ports on the case dont have a cable connecting them to the PSU or the motherboard, and I have no clue what the problem with the motherboard ports is. On the part picker website I used it said the build would require approx. 396 watts. Plz don't go to hard on me, this is my first ever pc build
Motherboard - MSI B450M pro-vdh max
GPU - MSI Ventus RTX 2070
Tower - Corsair Carbide Series Spec 05 Mid Tower
PSU - Corsair CX 450M (450 watts)
Processor - AMD Ryzen 5 3600X
Edit: There is one very very light scratch on the motherboard next to where the graphics card is, because when I was inserting it, the metal jutting out slightly came over the motherboard. i don't believe that would be enough to ruin the ports though...
