B450M Pro4 No Video

I recently built a new PC but am not getting video (seems to be a common thing with this moboard).

Here is what I'm using:

* ASRock B450M Pro 4 motherboard
* AMD RYZEN 5 3600 6-GHz (4.2 GHz Max Boost) Socket AM4 65W
* G.SKILL Ripjaws V Series 16GB 288-pin DDR4 SDRAM DDR4 3200 (PC4 25600) Desktop Memory Module (?4)
* 1000W ATX Power Supply Quiet Gaming 14cm Fan Dual SLI Ready for VGA ATI nVidia

Note: I had to send the PSU back as it didn't fire up, so I'm presently using a Thermaltake TR2-430W PSU just to see if the moboard fires up, which it does, but I have no video output.

I've tried switching around the RAM sticks to different sockets, but no change. I don't even hear any beeps coming from the onboard motherboard speaker (does it even have one? I dont see anything that resembles one).

Any suggestions?

I'm not using any video card, just the onboard video. Does the motherboard require use of a video card? This is my first attempt at building a computer in about 15 years.

Would this video card work?

Sorry if I'm asking (what could be) a dumb question...I now see that building a new PC has definitely changed since I last did it.

oops .. thats an RX570 .. not RX5700 .. the RX570 is a good budget card and does decent at 1080p gaming. I run one in my daughters rig paired with a 3600x, 2 16GB PC3000 on the ASRock Fatal1ty B350 Gaming ITX/ac. She plays Fortnite, Destiny 2, Forza 4(?) ..and other games at 1080p real nicely.

Alright! .. have fun with your new build!
