Question No Video From GPU

[Antedon]

So I have recently built a new PC upgrading from a really old rig and I have ran into a problem. The motherboard powers up fine and the fans in both the GPU and cpu are running but I'm not getting any video output from the graphics card. The graphic card definitely works since I tested it on another rig and it outputs fine.
Specs:
CPU: AMD A8-9600 3.1 GHz Quad-Core Processor
Motherboard: ASRock A320M Micro ATX AM4
RAM: Patriot 8 GB 2666
GPU: 1050 Zotac Mini
Power Supply: 450 watts

I can't connect the APU as a video output since the motherboard does not support onboard graphics. Does this mean the mother board is using the APU automatically even though it doesnt support onboard graphics?

The Model for the PSU is EVGA silver edition
The gpu is used but I was the one using it. The gpu works fine on my other rig but however its not working on this rig.
