Black Screen on monitor when connected to my brand new pc, but works fine when plugged into my Macbook Pro 2014 13"?

Hey everyone,

So today I built my first PC, super hyped up and started building it with these brand-new components (not sure if it makes a diff but I used a low strength magnetic tip screwdriver in assembly):

GPU: MSI Geforce GTX 1660 Super
CPU: AMD Ryzen 5 2600X
RAM: Corsair 2x8GB sticks
Storage: 1TB Silicon Power SATA SSD
Motherboard: Gigabyte B450M DS3H
PSU: EVGA 600W 80+
Case: NZXT H510

Once I had the build all set up, I turned the PC on, and the case fans, CPU fan, and GPU fans starting running as well as the motherboard amber light showed up indicating that it was receiving power. I had Windows ready to install on my USB key which I plugged into one of the motherboard USB ports and powered on the PSU, then the power button, and connected the HDMI cable from my monitor that was connected and working with my 13" Macbook Pro into the HDMI port on the motherboard.

However, the monitor screen stayed black. I've spent the past 4 hours trying to figure out the problem. I've unplugged and replugged the CPU pins, RAM sticks, and GPU but no change. I tried plugging the HDMI cable into the port on the GPU, no difference.

If anyone could help me troubleshoot and set up my PC it would be greatly appreciated and I'm more than happy to provide pictures of the build if necessary :)

Have you connected 6-pin and/or 8-pin PCIe power cables to the GTX 1660 card?

As regards plugging monitor in to the motherboard ports, those ports don't work anyway because the Ryzen 5 2600X doesn't have an integrated GPU. The only GPU you have is the 1660.
